Ever since I installed 8.1 my battery seems to be draining fast.. like it's not sleeping. Also sometimes when I go to wake it up it's turned off. Anyone else having any issues? Typically was charging it once a week.. now about double that.
They are inside the W510 driver package. When you install it should display a spalsh screen that says "Intel". Do parts of the case feel hot ? Particularly the upper right rear ? Any USB devices connected ?
First off uninstall the Microsoft Intel GFX drivers (1160) installed during the 8.1 upgrade, they conflict with the provided DPTF power management. Install the latest driver package 2.12 for the W510 http://www.acer.co.uk/ac/en/GB/content/drivers this has an Acer version of the same Intel GFX drivers 1160 and allows the tablet to sleep correctly.
jpearn, I followed the steps you provided, but still having problems with the W510 sleep. This morning it wasn't starting and the top right part of the tablet was pretty warm. Had to reboot it to get it to work. I have it to shut down now when I close the lid. For some reason I don't see a hibernate option in the power settings, do you know how I can get it?
My graphics driver ver. is 22.214.171.1242 from the last drivers package 2.12.
