Let me just drop another quick post regarding the Acer W510. This time with regards on how the batteries seem to work. If you bought the version with the keyboard, there's an additional battery inside of it which would extend the total running time of the W510 to > 10 hours.

At first I thought it would do so by letting the keyboard's battery charge the tablet's battery, but according to the information shown by Windows that wasn't the case.

To Windows, there are two batteries running in parallel to help distribute the current load on the batteries. While I found this to be a bit surprising I didn't think too much of it until I realized that if the tablet's battery was already flat the keyboard can't be use to help top up the tablet's battery so it can be used independently again. This was a bummer after I realized that... until I figured out an interesting quirk...

The keyboard WILL charge the tablet if the tablet is COMPLETELY OFF. Here's a video explaining the quirk.

So to recap,

  1. Shut down Windows
  2. Wait for shut down to complete, you can tell when the thing stops rumbling when you press the Windows key on the tablet.
  3. Plug the tablet into the keyboard
  4. See charge light appear!
