Asus has announced laptops powered by Snapdragon X-series processors. This news follows Qualcomm’s announcement earlier today (click here to learn more).
The Vivobook S 15 (model S5507) is also the company’s first Copilot+ PC laptop, marking the first time a Vivobook doesn’t use an Intel chip. However, despite the transition to Snapdragon X Elite, the Vivobook S 15 retains the same impressive OLED display as its predecessor.

The 15.6-inch screen supports resolutions up to 2880 x 1620, a 120Hz refresh rate, and a peak HDR brightness of 600 nits. In terms of internal configuration, the Vivobook S 15 provides users with two Snapdragon X series processors to choose from: 12-core Snapdragon X Elite or 10-core X Plus. This notebook also supports up to 32GB of onboard memory and 1TB (PCIe 4.) SSD storage. Additionally, it supports Wi-Fi 7, ensuring users get the best wireless speeds.

However, one of the most attractive features of the Vivobook S 15 is Asus’ own proprietary StoryCube. Asus says StoryCube is “the smartest, most convenient and powerful way to manage all your digital assets, using artificial intelligence to assist in sorting, editing, managing and exporting captured raw files.” With the help of Snapdragon X processor NPU, with its powerful features, users can expect accelerated performance in a variety of AI-powered applications, including Windows Studio Effects and Cocreator — but we won’t make any judgments until we get our hands on a Snapdragon X-powered laptop.

This is the most expensive laptop we’ve seen to date. David Hollingworth considers whether you’re getting what you pay for Design-wise, Alienware’s high-end gaming gear can often be either liked or disliked based on looks alone. The company’s design philosophy is so unique that people either love it or hate it; which is why we were quite surprised when this rather understated laptop came through for our testing.
In fact, its simplicity could almost be called retro, and if it weren’t for the alien-head logo in the middle of the flap, you might think of it as an ancient desktop replacement from the past. Flip the lid back, though, and you’ll find Alienware’s designers are still hard at work. Apart from

A standard laptop keyboard and panel might not be much to look at except for the non-standard font on the keys, but open up the m15x and it’s a completely different story. Keyboard letters, outlines, and various other bells and whistles light up from within. There’s even a slim strip of lighting along the entire edge of the screen bevel and touchpad!
This may seem a bit too flashy, but if you’ve ever been in a dark room staring at your keyboard trying to find the B key to bandage yourself in a game, only to hit the G key instead, this is pretty cool. Even better, you can completely indulge in adjusting each piece to one of ten or so colors, from icy blue to dangerous red.

There are more than enough ports scattered around the left and right sides of the phone, and thankfully there are no ports on the back. Of particular note are the USB 2.0 ports and HDMI outputs on either side of the keyboard for high-resolution output on a large screen.

Speaking of bigger screens, the other thing that was obvious from the get-go is that the 15.4-inch screen on the m15x is, well, just a 15-inch screen. Many “gaming grade” laptops opt for 17-inch models – so they’re heavy and take away from portability a bit. The 15-inch screen is still very useful and requires less effort. It’s an interesting choice, and we think it’s a smart one in the long run.

But all the smart choices in the world are for naught if your well-thought-out gaming laptop can’t keep up with the pixel requirements. With an 8800 GTX, you can expect good performance – and you won’t be disappointed! When we realized someone had secretly turned on the m15x’s “stealth” setting (and thus reduced performance to save battery life) and left our machines running at maximum speed, both 3DMark06 and Crysis returned pretty impressive scores.

The former scored a respectable 9312 3DMarks, easily beating the Dell M1730 for the top spot, and ran Crysis at 1280 x 1024 resolution with all settings cranked up quite a bit – averaging 12fps was no mean feat. Turn those resource-intensive settings down a bit and you’ll get a smoother gaming experience, but frankly, it’s smooth enough even at high settings.
Our only option – and a common choice for high-end systems – is 4GB of RAM. The m15x isn’t running a 64-bit OS, so with the 512MB of onboard video taking up Vista’s allocation limit, you’re just wasting all that RAM. 2GB is a more realistic number and brings the price down a bit.

That said, while you’re paying a lot for the m15x, you’re at least getting some great performance, great peripherals (like a Blu-ray drive), and some unique lighting and flash.

Toshiba is looking to position itself as a laptop with the Toshiba Satellite L55t. This 15.6-inch laptop features powerful processing power, a vivid touchscreen, and an incredibly comfortable keyboard. However, it doesn’t come with Intel’s latest Haswell processor and comes with a slightly mediocre 4-cell  Toshiba Satellite L55t-A5290 laptop battery . With Staples on sale for $713 (after discounts), should you stop by and pick up an L55t?
design
The Satellite L55t looks like the previous generation of Toshiba’s Satellite series laptops: The L55t’s lid and base are made of silver-gray plastic instead of the Satellite P55t’s elegant brushed aluminum design, and the keyboard comes with a glossy black plastic stand. A subtle horizontal stripe pattern breaks up the monotony of the lid and base, and a silver Toshiba logo is printed on the lower right corner of the lid.

The L55t measures 14.9 x 9.6 x 1.13 inches, weighs 5.4 pounds, and feels thicker than the competition. The $679 Satellite P55t is slightly thicker than the L55t, 1.2 inches, but weighs just 5.2 pounds thanks to Toshiba’s new Skyline design. The $699 Acer Aspire M5 measures 15 x 10.08 x 0.68~0.9 inches, weighs just 5 pounds, and feels very thin in comparison. Click to enlarge The latest 1080p The Wolverine trailer looks rich and vivid on the Toshiba Satellite L55t’s 15.6-inch, 1366 x 768 TruBrite display. Exploding orange flowers stand out against the snow-covered Japanese dojo, and we can make out details like the decoration on the Assassin Samurai’s armor.
Vocal Music
The living room of our apartment filled with a roaring baritone choir as we listened to Jeremy Soule’s majestic score for Skyrim. Thanks to the laptop’s DTS Sound software, the audio was virtually distortion-free even when we turned the volume up to 100%, and allowed us to fine-tune the settings for bass, voice, and treble. For quick adjustments, DTS Sound also offers surround, maximum volume and bass boost options. We don’t recommend disabling DTS sound: the audio sounds distant and harsh.
Keyboard and Touchpad Click to Enlarge The Satellite L55t’s island-style keyboard is a pleasure to use thanks to its generous travel and textured keys. The keyboard has almost no flex, and Toshiba was thoughtful enough to leave enough space between the keyboard and the number pad so we didn’t accidentally hit the wrong key when trying to use the Backspace, Enter, or right Shift keys. On the Ten Thumbs typing test, we hit a typing speed of 68 words per minute, which was slightly above our average.
Unlike mainstream laptops like the Toshiba Satellite P55t and Acer Aspire M5, which use Intel’s latest Haswell chipset, the Toshiba Satellite L55t comes with an older Ivy Bridge processor. Still, its 1.8 GHz Core i5-3337U CPU and 8GB of RAM deliver smooth performance, even under heavy use. For example,  in the OpenOffice spreadsheet test, the Satellite L55t matched 20,000 names and addresses in 5 minutes and 50 seconds. That’s about average for the class, but slightly slower than the Satellite P55t (5 minutes, 14 seconds) and the Aspire M5 (5 minutes, 15 seconds).Aspire M5 Battery Life
Toshiba Satellite L55t battery  life
Click to enlarge Power-hungry power users will wish the Toshiba had equipped the Satellite L55t with Intel’s power-saving Haswell chipset instead of the older Ivy Bridge CPU. In the Toshiba Satellite L55t laptop battery test (continuous Internet access via Wi-Fi), the Satellite L55t’s 4-cell lithium-ion battery lasted 4 hours and 43 minutes. That’s well below the mainstream average (6:11) and the Toshiba Satellite P55t (5:32). The Acer Aspire M5’s 4-cell 3560mAh lithium-polymer Toshiba Satellite L55t battery lasts up to 8 minutes and 55 seconds.Click to Enlarge Like the P55t, the Satellite L55t comes preloaded with a number of Toshiba-branded apps. These include Toshiba App Place and Toshiba Book Place, where you can download (you guessed it) apps and books; Toshiba Start, which acts as a pseudo-Start menu and news aggregator; and Toshiba Central, which offers user guides and support pages the link to.
Third-party apps include Evernote Touch, StumbleUpon, Netflix, Electronic Arts’ Origin, and one-year subscriptions to Norton AntiVirus and PC Checkup. Microsoft-branded applications include trial versions of Skype, SkyDrive, and Microsoft Office 2013.
The Toshiba Satellite L55t-A5290 comes with a one-year parts and labor warranty. Find out how Toshiba fares in our Best and Worst Brands report and Tech Support Showdown.
Configuration
In addition to the configuration we reviewed (1.8 GHz Intel Core i5-3337U CPU, 8GB RAM, 750GB 5,400-rpm HDD), Toshiba offers several other configurations of the L50 series on its website. Prices for these configurations range from $429 for the Satellite L50D-ABT2N22 (1.7 GHz AMD quad-core A8-5545M accelerated processor, 4GB RAM, 320GB 5,400-rpm HDD) to $799 for the L50-AST2NX3 (2.4 GHz Intel Core i7-4700MQ) USD CPU, 12GB RAM, 1TB 5,400-rpm hard drive).
In summarySoftware and warranty Click to enlarge The 15.6-inch Toshiba Satellite L55t-A5290 ($713 at Staples) has a touchscreen, loud audio, and a great keyboard and trackpad. The laptop’s design looks a bit dated, though, and it must use a third-generation Intel CPU. The $699 Acer Aspire M5 is a better deal, as it offers an aluminum lid and panel, Intel’s new Haswell architecture, and nearly twice the battery life of the Toshiba Satellite L55t.
The Toshiba Satellite P55T is also better than the L55t in terms of cost performance. This $679 15-inch laptop from Best Buy has a newer Haswell chip, 45 minutes more battery life, and a sleeker body. Overall, the Satellite L55t is a great, affordable touchscreen laptop, and there are plenty of better options out there.

Gateway revamps its aging thin-and-light laptop design with the new M320. Gone are the square touchpad, square mouse buttons, and wasted wrist rest space. Their absence results in a case that is thinner and lighter, with some thoughtful touches like a convenient 4-in-1 card reader for flash memory cards and a coated rubber wrist rest that helps keep your hands in place while typing. layer. Although there are several configurations to choose from, the M320 we tested included a number of nice components, such as a speedy 1.7GHz Pentium M processor; a large 80GB hard drive; and a versatile DVD+/-RW drive. Despite being powered by a low-end Intel 855GME graphics chip, the system achieved respectable scores on CNET Labs’ mobile benchmarks, beating out most thin-and-light rivals while keeping pace with the powerful IBM ThinkPad T42. Unfortunately, in our lab’s battery drain test of the IBM ThinkPad T42, things weren’t so positive – the M320 came in last, with TheGateway M320 battery life is just 150 minutes of usage. Given the disappointing battery score, we have a hard time justifying the M320’s $1,800 price (as of September 2004); for the dollar, the slightly more expensive ThinkPad T42 offers far more value. Weighing just 5.5 pounds and measuring 12.9 inches wide, 10.5 inches deep, and 1 inch tall, the Gateway M320 is one of the smallest thin-and-light laptops and is 0.2 pounds lighter than the smaller IBM ThinkPad T42. Still, the M320’s full-size design elements make it feel large. Its bright 14.1-inch screen is bright enough for long workdays, but the native resolution of 1,024×768 doesn’t allow for extremely detailed graphics. The system’s keyboard, touchpad, and mouse buttons are also larger. Like the HP Pavilion zt3000, the right side of the M320’s The touchpad is enclosed for easy scrolling. We wish the M320 included the on/off button for the zt3000’s touchpad, as our thumbs were kept brushing against the touchpad while typing, resulting in unnecessary cursor hide-and-seek games.
The M320 has integrated 802.11b/g wireless, which you can activate using the keyboard’s function keys; a row of helpful blue LED status lights below the touchpad will show you when Wi-Fi is on, when AC power is plugged in, and Other system statistics. We like the rubberized coating of the wrist rest, which provides a secure feel while typing. The integrated DVD+/-RW drive is a fairly rare feature in such a lightweight system.
While we like the M320’s overall build, we’re unhappy with its graphics chip: the Intel 855GME, which borrows a whopping 64MB of video RAM from main memory. The chip didn’t hurt the system in CNET Labs’ mobile performance benchmarks, but we know it will struggle when faced with demanding graphics tasks. We wish Gateway offered a better chip option, like the 128MB ATI Mobility Radeon 9700.
Since it’s intended for both home and business use, you can buy the M320 with Windows XP Home or XP Professional. Gateway bundles enough software to get you started; it includes the Microsoft Works mini office suite, Ahead Software’s Nero Burning ROM for CD and DVD burning, and CyberLink’s PowerDVD for DVD viewing. You can also purchase dozens of optional games on Gateway’s website.
Mobile app performanceWe tested the Gateway M320XL, the most powerful configuration of the M320, equipped with a 1.7GHz Pentium M. Its performance is about 12 percent faster than most other laptops we’ve tested with the same processor; however, the M320XL’s performance is virtually identical to that of two newer systems, the IBM ThinkPad T42 and WinBook W360. That said, all three systems are solid, with the Gateway M320XL getting the job done for office, productivity, and content creation applications.
The Gateway M320XL laptop battery life is disappointing. Despite its 49WHr (watt-hour) battery capacity, it only lasted 2.5 hours in our power consumption test. The WinBook W360 has a similar 49WHr battery that lasts nearly 3.5 hours, and the IBM ThinkPad T42 has a 48WHrIBM ThinkPad T42 battery that runs strong for 4 hours. Two and a half hours isn’t bad, but we expected more from the Gateway M320XL Batterylife analysis was written by Eric Franklin, assistant lab manager at CNET Labs.

Dell Latitude E7440: PerformanceThe Core i7 chip inside this machine is a low-power part, so its specs are a mix of high-end numbers with inevitable compromises. Regular speeds of 2.1GHz are decent, with Turbo Boost peaking at 3.3GHz, but the part only has two hyper-threaded cores—the full-power mobile Core i7 has four cores.

The chip has an Intel HD Graphics 4400 core and is paired with a generous 8GB of RAM. It’s not the most powerful integrated chip in the Haswell Core i7 segment, but it’s on par with chips offered by Dell’s competitors. The Latitude’s PCMark 7 score of 4,705 is a good score between the Sony and Lenovo systems, and more than adequate for work—from browsing the web and running a word processor to working with demanding databases and even high-definition photos. In GeekBench, the Dell scored 5,941, an excellent result that trailed only machines with full-fat mobile Core i7 CPUs. During our testing, the vast majority of apps got up and running quickly and smoothly. Only the most difficult office applications will prove inadequate for this machine. Powering the Dell’s performance is a 256GB LiteOn SSD. The sequential read and write results of this hard drive are 477MB/s and 396MB/s respectively. Although it is not top-notch among SSDs are several times faster than any mechanical hard drive. This means software load times are fast, and it also means the system boots up in just 14 seconds – an impressive result that will help you get to work faster.
The HD Graphics 4400 chipset scored 35,720 on 3DMark’s Ice Storm benchmark. That’s about 2,000 points higher than Lenovo and more than double Sony’s score. It’s not powerful enough to play modern games at anything but the most modest settings: On Bioshock Infinite’s very low-quality test, we dropped it to 1,024 x 768, but still only managed 16fps.
Dell Latitude E7440 16
Dell Latitude E7440: Heat and noiseWhen it comes to thermal performance, the Latitude E7440 has few issues. We didn’t notice the Dell’s fans when performing day-to-day tasks like web browsing and word processing, and while the internal spinner cranks up a notch when running more intensive applications, it never gets above a low hum, and not too distracting. Its sonic performance is similar to the Sony machine and almost as impressive as the Lenovo machine.

We didn’t experience any heat issues, either—any warm air the Latitude generates blasts out of a small vent on the left edge. There’s a small grille on the base, and the bottom panel does get a little warm, but it’s far from Uncomfortable. The keyboard and trackpad stay cool, too.

At least a spare 47Wh can be purchasedDell Latitude E7440 laptop battery for £107. If that’s a bit too much, the 34Wh battery costs £90.
In our PowerMark test, the Dell lasted 6 hours and 4 minutes. That’s a reasonable score, better than Lenovo’s, but still not as good as the Sony VAIO Pro 13’s 6 hours and 30 minutes, or theMacBook Air’s batterylife.
We plugged the laptop back in and measured thelaptop batterylevel after 30 minutes of charging. The Dell charged 31% during this period, not far behind the Sony but far from the Lenovo, which has a fast-charging system that charges to 77% in just 30 minutes.

At around £500, the Asus Vivobook Go 15 OLED is a simple device on paper. The Asus Vivobook Go 15 OLED’s long battery life and stunning screen offset its relatively low workflow performance expectations, delivering decent portable entertainment value for the right person or family. ASUS Vivobook Go 15 OLED has longASUS Vivobook Go 15 OLED batterylife With around 8 hours of runtime on a 90-minute charge under office workloads, this laptop can last a long time.introduce
OLED technology has developed by leaps and bounds in recent years. What was once a very expensive item in a laptop is now much more common – and the price doesn’t automatically go up that much. The Asus Vivobook Go 15 OLED is the latest device to benefit from this, offering a compelling value proposition for the right light user.
High-end Vivobook laptops still flaunt OLED panels as a premium upgrade, while ASUS’s slim and minimalist Vivobook Go series is starting to feature gorgeous mirror screen technology as standard. Squeezing a brightly colored display into a £500 machine is a quick and easy way to boost the limited appeal of a budget laptop.
All the ports you need are on both sides of the device, with barrel chargers, full-size HDMI, USB-A 3.2 Gen 1, USB-C 3.2 Gen 1, and a headphone jack hidden into the right side, leaving a speed A slower 2.0 USB-A port protrudes on the left side, used for charging the best wireless mice and more. It does stick out and looks a little out of place, but it’s no closer to the ground than a multiport array on the other hand. Both are kept from touching your desk by large orange rubber feet, which also happens to be the only splash of color you’ll see on the entire chassis. The lid is also a bit prone to fingerprints when exposed to bright light, so you may want to have a cloth handy if you take it to a cafe.
The keyboard itself is full-sized, but squeezed together a bit on the 15-inch model to accommodate everything. The downside to this is that it may take some time to adjust to placing your hands more on the left side, but the adjustment period is to be expected when replacing the keyboard. This may take a little longer than expected.
Despite being all-plastic, we’re happy to report that the Asus Vivobook Go 15 OLED does come in a very slim and recyclable packaging.

The cardboard thin sleeve showcases the company’s sustainability efforts and even includes a QR code to dress up the unboxing experience with some cute AR magic. As far as we can tell, the handle is still plastic, but pull it off and it’s easily thrown into the recycling bin. In the sub-£500 range, it’s great to see the Asus Vivobook Go 15 OLED sporting a large 15.6in OLED display. OLED naturally avoids most of these issues and offers superior color representation, replacing traditional LED or LCD panels where color accuracy can vary widely even on much more expensive machines.A colorful viewing experience. It takes away the hassle of researching to find the best panels for the price. The Asus Vivobook Go 15’s overall performance isn’t enough for studio-grade video and photo editing, where accurate color reproduction is key, but you ‘ll at least be able to view your content in the best possible way. Whether it’s for professional photography, your next Netflix binge, or your kid’s prescribed 50th viewing of Disney’s latest animated blockbuster, it’ll look great compared to your aging TV. As long as you don’t push it to the absolute edge, the Asus Vivobook Go 15 can still get you through most of the day comfortably.

Taking about 8 hours of the PCMark Office stress test (simulating a busy day with spreadsheets, word processing, and video calls), you’ll only start to deviate from that number if you turn up the brightness, take a few too many YouTube interruptions , or maybe decide to fire up Solitare And forgot to turn it off after lunch. Even so, you can still get through most of the day without having to reach for a portable 65w charger.
These days, it’s nice to see the budget Asus Vivobook Go 15 OLED laptop achieve Ultrabook-level battery life, but it’s still disappointing to see a reliance on barrel connectors to power it.

The Asus Vivobook Go 15 only takes about two hours to fully charge while in use, it’s not the fastest device to get back to a full charge, but at least it doesn’t run out of juice in the same amount of time. If you do need a few more hours of gaming, ASUS Vivobook Go 15 battery  saving settings and dimming the screen can push you past the 8-hour baseline. You just have to sacrifice some usability. Those larger spreadsheets may have to wait until tomorrow .

The Dynabook Portégé X40L-K is a lightweight business laptop that looks great and performs well, but it does have some shortcomings, such as its webcam. The Dynabook Portége X40L-K is a high-end business laptop that doesn’t try to do anything too fancy, instead focusing on perfecting the basics. In that sense, it did its job. This is an ultralight laptop that offers almost everything you need to have a good experience. I really like this laptop. It has a beautiful display, the keyboard is excellent, and it looks good while still being discreet and professional. Even the speakers are very loud, perfect for media consumption or phone calls. Dynabook provided the Portégé X40L-K for this review. However, the company has no input into its content and does not provide any form of compensation for its production. Design: Super light and looks great

The Dynabook Portégé X40L-K comes in a dark blue that’s subdued but unique enough to stand outIt uses a magnesium chassis, which is very light and easy to carryBusiness laptops have always looked a bit boring, and based on my past experience, the Dynabook doesn’t do much to change that perception. Thankfully, with this model, things are a little different. The Dynabook Portégé X40L-K comes in “Tech Blue Metallic,” which means it’s dark blue. It’s bright enough that you won’t really get confused and think it’s black, but it’s dark enough that it’s still perfect for an office environment without any weird looks. Display and sound: The screen is clear enough and the speakers are loudDynabook Portégé X40L-K features a WUXGA display that’s clear enough without using too much powerFour-speaker system can pack a punch for media consumptionDynabook has been surprisingly conservative when it comes to laptop displays. Even today some of its laptops start with resolutions of 1366 x 768 and you won’t find anything sharper than Full HD, or in this case WUXGA which is essentially the same as Full HD but with less width and height The ratio is 16:10. That’s totally fine, though, and Dynabook seems to be really focused on delivering a solid experience without overly fancy specs, which is totally respectable.
Keyboard and Touchpad: Very comfortable to type onThe keyboard on the Dynabook Portégé X40L-K feels great to type onIt has a big touchpad, but the surface is a little grippyOne of my favorite things about the Dynabook Portégé X40L-K is the keyboard. I’ve used some good laptop keyboards, and the recent Lenovo ThinkBook 13s is one of my favorites, but I think I might actually prefer this one. The travel of the keys is nice and comfortable, and they don’t feel jarring when they bottom out. It feels like it requires more power than other laptops, but I actually prefer that. Typing on this keyboard feels great, it’s definitely one of the best keyboards I’ve ever used. The power button is an odd exception, by the way – it feels soft and a bit hard to press, and I can’t remember the last time I saw anything like it. Performance: What we expect from the Intel P-SeriesThis model has an Intel Core i7-1270P processor and 16GB of RAM, so it performs very wellIntel P-series processors continue to impact Dynabook Portégé X40L-K batterylife
As you might expect from a top-tier business laptop, the performance of this machine is quite impressive. It is powered by an Intel Core i7-1270P processor, which means it has a TDP of 28W, has 12 cores and 16 threads, and the P core can boost up to 4.8GHz.
This should give you plenty of performance for a variety of work-related tasks, and having 16GB of RAM to back it up also helps, but it’s worth noting that the RAM is soldered to the motherboard, so you can’t upgrade it. I never really wished for faster performance from this machine. You can see how it compares to similar machines below. As for  Dynabook laptop batterylife, it’s not great, but it could be worse. Overall, I lasted between 4 hours and 21 minutes with the screen on, giving it about 6 hours and 6 minutes. One time I only got about 3 hours and 38 minutes, but that was a deviation and I never got that low again.  Dynabook Portégé X40L-K battery  life hovers around 5 hours in most cases, and often a bit longer. That’s not surprising, but it’s much better than laptops like the Lenovo ThinkBook 13s or Acer Swift 3, which have Quad HD displays. Here, the use of a Full HD panel works in the Dynabook’s favor, and you might actually consider taking this laptop with you to get some work done on the go. If it’s a full day’s work you’ll still need to plug it in, but for me the bar was set pretty low and this is still good in comparison. Should you buy the Dynabook Portégé X40L-K?
I was really surprised by a lot of what Dynabook did with the Portégé X40L-K. It’s a very nice looking laptop that’s also very light and easy to carry, it has a tall display that’s great for productivity work, and it has one of the best keyboards I’ve ever used. It even has a very loud speaker system, which I didn’t expect to be the focal point of a business laptop. Performance is solid, too, and the  Dynabook Portégé X40L-K battery   llife, while not great, is more tolerable than other machines I’ve reviewed.

Back at IFA 2014, Lenovo launched the ThinkPad Helix 2 Ultrabook as a replacement for its original ThinkPad Helix model, which fIt isatures an 11.6-inch HD 1080p IPS display and takes advantage of 3rd generation Intel Core processors (up to i7) .
Lenovo promised at the time that the convertible would be available in time for the holidays, and the company has kept its word, offering the 2-in-1 starting this week.

Interestingly, Lenovo skipped an internal upgrade step on the Helix 2. The new tablet/laptop hybrid won’t take advantage of the Haswell platform, instead relying on Intel’s new Broadwell-based Core M chips.
The Helix 2 is basically a tablet with a docking keyboard, allowing customers to use the device as a laptop. The entry-level variant features an 11.6-inch display with a resolution of 1920 x 1080 pixels and is powered by an Intel Core M 5Y10 processor coupled with 4GB RAM, 128GB internal storage.
This model also comes with 802.11ac Wi-Fi, Bluetooth 4.0, and an active digitizer and a digital pen of Wacom variety.
The hybrid keyboard is a magnetic accessory that connects to the display via small pins on the bottom (so there’s no Bluetooth activity involved).
Lenovo also offers more advanced variantsFor more demanding customers who want their convertible to be a little faster, Lenovo has a fancier version waiting for you, with a Core M 5Y70 processor, 8GB of RAM and 256GB of internal storage.
The Lenovo ThinkPad Helix 2 is one of the first machines to feature Intel’s new Core M platform, which consumes slightly more power than Atom processors but delivers better CPU and graphics performance.
The specs list also includes a microSD card slot, USB 3.0 port, micro HDMI output, and stereo speakers. Open the keyboard and you get a USB 2.0 port, two more speakers, and an extra battery.Lenovo ThinkPad Helix 2 laptop batterylife is also positively impacted, so in tablet mode the Helix 2 can last up to 8 hours, while in laptop mode users should be able to squeeze out up to 12 hours of runtime
