So I have this laptop, with Windows 7 Ultimate. When the laptop isn't plugged into the wall (running on battery), i can get maybe 10 minutes (if i'm lucky) of power before it just *POW* shuts off. There's no shutting down process. I can't turn it on after this until I plug it into the wall. I know when I first got this laptop, the battery life was about 3 hours (it's a beast laptop, not one of those 10-hour things). Now, when running on battery, it says it could last 30 minutes. But it lasts much less. Help? Quick facts: Windows 7 x64 Ultimate Acer laptop One year old Shuts down on battery power ONLY, after a few minutes of non-intensive process (internet, etc) Annoying Thanks in advance!
