Resposta para "Why does my battery drain fast when I'm not using the device?"I'm running bios 306. When I use Asus Live Update to scan for updates 307 isn't shown as an update. I've read on some postings that 307 is for the computers with a hard drive, but not sure if that is correct. I'm going to stay with 306 since it is working for me. I too was having issues with the battery draining when it was in storage. I only use my T100 occasionally. I changed the settings in "Change what closing the lid does". When it was set to put the computer to sleep on battery when the lid was closed the battery drained. I changed the setting to "shut down" the computer when the power button is used, or the lid is closed while on battery and the battery is now staying charged.
