My son has had his Acer Aspire One since Christmas of 2008. Last week, my son plugged in the computer to charge the battery and no screen would come up, it stayed black. He and I looked in the handbook that came with his computer. We tried all three of the suggestions but with no luck. The screen remains black although the green power light is on. I've had no luck reaching Acer customer service. Can someone please help? I hate to think I need to get my son a new computer already!!

Go to http://www.youtube.com/watch?v=l6GRhsvP-og this will explain all its has worked for me twice just make sure you use a usb flash drive not a memory card it will take 10 mins to do its quite simple your guna need to re-flash the bios.

Let us know what you tried to fix it. Her is what I will do:

1/ try to start without battery only with power plugged on (sometimes it doesn't work without battery connection on)
2/ Measure with a voltmeter the power out from the battery
3/ Replace battery (cheap one on ebay)

If after that nothing happen the the motherboard is probably screwed...Sorry.
You can still sale it for parts..

Good luck and don't forget to rate.
cheers
