your computer has a internal battery and it possible that it died and you can take it apart your self or take it to a shop or a friend that plays with computers have them replace the batter, after installing new battery just turn it on and it will reboot and every thing will be okay

if the password is in windows just reload windows using your disc to boot up too don't forget to press f12 at boot to get temporary boot screen up ansd the password will be gone easy fix

WOW, sounds like a bios password.

The Acer Aspire One has built-in BIOS recovery which can be used to flash its BIOS. Once the BIOS has been flashed, all BIOS settings are reset to default which gets rid of the BIOS password. This procedure has been posted Aug 2008 on macles for friends of the aspire one to address the BIOS failure that frequented early versions of the Aspire One BIOS. I have used the procedure on my own Acer Aspire One when it bricked in the fall of 2008 and once more in 2009 to install a later BIOS version. Acer also posted Feb 2009 the similar procedure on AcerSupport but has since removed it. Be aware that you must follow the procedure carefully and do so at your own risk. Here is the macles link.

Locate and download a program called "OPHCRACK"

Insert disc and restart computer:

Set your bios to start from the CD:


Just press F8 or whatever the screen says for the BIOS settings and/or options..
Set the boot option order to CD first rather than second or third.

The program will run and it will start to recover the passwords(s)

similar story trying to fix friend's 5420. She had trashed Vista and lost any&all original discs. Well, who needs vista anyway...it's not one of M$'s better efforts. TRY THIS, download LinuxMint from a reliable source, burn a "live CD". put into drive, boot machine, during boot press "Alt"+"F12", select CD to boot from. See how it feels. Wait couple minutes for boot to finish then manually click on tiny icon next to network icon to load wireless driver, (don't ask...), on bottom right of screen. Learn some new stuff, toss some windows. enjoy.

try to hit F10 or F12 for booting the windows..thanks..and good luck...^_^
