Lenovo ThinkPad T410 Review

Lenovo proved at CES in January that its reputation when it comes to the latest generation of laptop technology is well-deserved. The company’s lineup ranges from small to large, catering to everyone from casual travelers to hardcore business users. There are also one or two machines aimed at gaming and multimedia users, although at first glance you might not guess that the ThinkPad T410 falls into that category. That machine, along with the T410, T510, and W510, all received a major upgrade last month with Intel’s latest Core i5 and Core i7 processors, injecting much-needed life into the traditionally sturdy and plain ThinkPad line. The T410 we’re reviewing today is a ThinkPad through and through. From top to bottom and edge to edge, there’s no doubt that this is a member of the iconic ThinkPad family. It’s finished in matte black and its styling is a little bland, but it’s built to last. Sounds like a ThinkPad, right? It has the same exterior that loyal Lenovo users know and love, but it’s the selection of components inside that we’re really interested in. Can the ThinkPad T410 maintain its all-business status while still performing at a level acceptable to multimedia enthusiasts?LenovoThinkPadT410 Laptop BatteryThose expecting the T410 to be a dramatic change from the T400 and T400s we reviewed will be sorely disappointed. Almost everything from the chassis to the keyboard to the trackpad is typical ThinkPad, but the Core i5 CPU (the Core i5-540M, to be specific) is a stark departure from last year’s ThinkPad options. It’s new on the inside, old on the outside — will that be enough to convince existing ThinkPad owners to upgrade? More importantly, will it entice any new customers who have so far resisted buying a machine with a blue “Enter” key? Read on for our full review to find out.

Wireless tech could replace Bluetooth at short distances and boost battery life 5-fold

This breakthrough wireless technology can extend the life of your smartphone or wearable device’s Radio Communication batteryup to five times on a single charge. Scientists have created a new wireless technology that could one day rival mainstream wireless communications technology Bluetooth. This new technology requires very little power and can extend the life of your device up to five times on a single charge.
Currently, the major wireless technologies embedded in devices such as smartphones, wearables, and smart home devices, including Wi-Fi, 5G, and Bluetooth, rely on classic radio configurations. They transmit data through electromagnetic waves generated by modulation of electromagnetic fields.


But alternative technologies rely on electric field modulation. Signal transmission equipment replaces the power amplifiers used in produce traditional wireless technology with voltage amplifiers that generate short-range electric fields. These voltage amplifiers also weak electromagnetic fields, but the receivers (untuned electrodes rather than tuned (Conventional radio systems produce electric fields alongside electromagnetic fields, but they decay very quickly and are not used to transmit information.)
The receiving device consumes power only when the receiving electrodes charge or discharge (a process called capacitive coupling), rather than continuously transmitting energy through the air as in classic radio configurations. As a result, the new technology, called Potential Sensing Communication (EPSComm) , consumes a fraction of the power of Bluetooth.


“This new technology means wearable and mobile devices will be able to run longer after being charged by the Radio Communication Battery. More fundamentally, it will be possible to use smaller batteries due to the energy savings brought about by this new communication technology and enabling further miniaturization of devices, which opens up new possibilities for tiny wearables such as ear-worn headphones (smart earbuds), smart rings, or even electronics integrated into clothing,” the University of Sussex said. Wearable technology professor Daniel Roggen told LiveScience in an email .
