Whether you’re in or out of work, the ExpertBook has got you covered with a 14-inch, 1080p bright and colorful display. If you’re looking for bumpin’ speakers, look no further than the Asus’ speaker system. The audio comes through clear, loud and impactful.We put each laptop through extensive benchmark testing — both synthetic and real-world — before they end up in the hands of our reviewers We evaluate each aspect of the laptop, including its performance, Asus ExpertBook B9450 batterylife, display, speakers and heat management.


In our benchmark testing, we use a Klein K10 colorimeter to detect the brightness and sRGB color gamut of the laptop’s display. For performance testing, we run the laptop through a gauntlet of benchmarks, including Geekbench 4.3 and 5.0 and 3DMark professional graphics tests. 


To determine real-world performance, we task the laptop to convert a 4K video to 1080p resolution and to duplicate a 4.97GB multimedia file. Our real-world graphics test is the Dirt 3 benchmark with medium settings at 1080p resolution.
We also run heat tests by playing a 15-minute full-screen video and measuring temperatures in different areas of the laptop. Last but not least, our battery test consists of continuous web surfing over Wi-Fi at 150 nits of brightness. For MacBooks and premium Windows 10 laptops, a runtime of over 9 hours is considered a good result whereas gaming laptops and workstations that can stay powered for longer than 5 hours deserve praise. 


These tests are complemented with extensive hands-on testing from our reviewers who critique everything from the laptop’s materials to the feel of its touchpad.

2. Lenovo ThinkPad X1 Carbon
Lenovo ThinkPad X1 Carbon (Gen 11) is a refinement of the best ultraportable laptop for business users. The newest X1 Carbon now flaunts a 14-inch, 16:10, 1920 x 1200-pixel touch display, which means it offers 120 more vertical pixels than your typical 1920 x 1080-pixel screen. Also improving productivity are a wider touchpad and a human presence detection sensor for convenient login and enhanced security. 
Swapping the engine for 13th Gen Intel chips adds considerably faster performance, but the  Lenovo ThinkPad X1 Carbon battery life upgrade is even more enticing; the Gen 11 model lasts for nearly 14 hours on a charge. These perks are packaged in a familiar matte-black design with an aerospace space grade carbon fiber lid. It’s super lightweight at 2.5 pounds, and it’s even incredibly thin at 0.6 inches.

3. MacBook Pro 14 (M3, 2023)
It’s amazing what a new heart can do for a laptop. The latest MacBook Air ushers in a new era for Apple with its custom-made M3 chip. There’s a reason that Apple has dominated the top of this page for so long. The company understands how to prioritize  MacBook Pro 14  batterylife in its chipsets, making the MacBook Pro 14 (M3, 2023) last for over 17 hours on a single charge. Listen, I’d love to have any other company at the top of this list, so laptop makers need to step it up.
Even on a 14-inch machine, Apple manages to pump out a super bright 3024 x 1964-pixel display. I’ll say it until I can’t breathe, but having a comfortable keyboard in a MacBook again is wild. It’s honestly a sad thing to be impressed by, but MacBooks are getting better every year, and the Cupertino-based tech company made the best decision by leaving Intel behind.
