Solved! How to reset bios on a acer aspire 5100



Do you mean enter the BIOS screens ? -- usually press Del or F2 key at boot up.

Do you mean reset the BIOS as per on a desktop computer where there's usually a jumper to do that ? Not so easy with a laptop -- best bet is to try to get into the BIOS screens and reset to defaults or a "safe" setting.

If the thing just won't start, disconnect the power cube and take the battery out. Then press the power button and then resinsert the battery and try to start it.
