Hello,
My mothers notebook was having the same problem.I really hope this is not too late, but perhaps this will help people in the future.
1. To boot the computer unplug and remove the battery
2. Then hold the power button to drain the bios- (30 to 60 seconds)
3. Then plug it back in, if it does not boot right away repeat step 2
4. Follow this link [http://support.acer.com/us/en/default.aspx|http://support.acer.com/us/en/default.aspx]
5. Find your computers support page and click the "Bios" tab
6. Update your Computers bios to the latest version (for my computer it was 2.14)
7. Restart and it will be fixed... Hopefully
I really hope this helped you. email me at cmullins1995@yahoo.com if you need more help
