SOURCE: Can not start Acer Aspire

If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.

On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.

    Reset BIOS? how to


    With both PC and LAPTOP Motherboards,Pc Motherboards are easier to Wipe Passwords than laptops because of ease of getting to the Jumper on the motherboard normally by the battery on the motherboard.I would suggest looking online for the motherboard manual which should show you where the bios reset jumper is.Laptops are just the same but a lot harder sometimes to find this jumper. Hope this helps

    I need the bios password of Acer 3610


    You need a bios master password that will clear your set bios password. I use http://www.unlockbiosrecovery.com/Unlock_Acer_Bios.php when I get an Acer laptop or notebook that has an unknown bios password. Happens often in my job repairing laptops. They charge $20 and guarantee it to work or your money back.
