New Surface Pro 3 firmware update should solve battery woes

A "limited number" of Surface Pro 3s can't charge completely

Surface Pro 3 owners who have had problems getting reasonable battery life from their tablets have relief coming their way. 

Microsoft pushed out a firmware update to Surface Pro 3 devices on Monday that's supposed to fix a problem that keeps the battery from charging all the way. An error in a limited number of devices causes the system to get the wrong charge capacity for the Surface Pro 3's battery, the company said. As a result, the battery isn't charged all the way, even though the system thinks it reached capacity. 

"Think of this like a fuel gauge in a car, where the car looks to the fuel gauge to determine how much to fill the tank," Microsoft said in a support document accompanying the update. "In this case, if the fuel gauge isn’t working right, the car would also not be able to fill the tank—even though the tank is fine."

The fix will show up in Windows Update as "Surface Firmware Update 8/29." When users install the update, they should make sure that their Surface Pro 3's battery is above 40 percent of capacity and that it's plugged into the AC adapter.

People who use the Surface Docking Station should take the tablet out of it and connect it to power directly. While the update is installing, it's important that the tablet remains connected to power. 

Then, after the update is installed, users should restart the Surface Pro 3 again. Once all of that is done, the battery fix should be applied. 

Microsoft is still exploring what to do for people who replaced their Surface Pro 3s outside of warranty as a result of the issue.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
