Hello,

I know this is not what you want to hear, but you will have to send it to Acer to have the bios password reset. I am an Acer authorized technician and I have tried everything under the sun to reset acer laptop bios passwords. Removing the bios battery won't do it. Please trust me on this one. In Canada Acer charges $100 for this service. Sorry I couldn't give you better news.

Regards,

Joe

SOURCE: Acer aspire 2920 bios password

Hi there,

Only way is to remove the CMOS battery for an hour or two and hook it back. It should work.
Optional is conatct Acer they would have a Default password for all the machines that they produce.

Post back if it is not working we will be happy to help you.
Hope this helps.
Cheers!!!!

SOURCE: forget bios password

hi ,
I had same problem, just remove plastic trim ( the one with the switches to power on etc etc ) and you will see a micro dipswitch. It should have all 4 switches to 0, move switch 1 to position 1 power laptop and password should be removed. Turn laptop off move switch 1 back to posiotion 0 and replace the plastic trim. It worked for me on an ACer Aspire 3610.

good look

HOW TO RESET BIOS PASSWORDS


Hello my friends, here i am. Today i am going to explain few tricks how to reset bios passwords, sometimes you forgot the password or some of your friends, coworkers, or family member set a password for BIOS (not system) and you forget or do not know it, it is a basic idea how to solve the problem. Find a jumper to reset the Bios on the motherboard, or remove the batery of the board,( not the lapatop batery if this is your case) First use common sense, somethimes put passwords like NAMES, PET NAMES, or THEIR BIRTHDAY DATE, if this not work try BACKDOOR passwords for your specific bios, google (I am googler fanatic) for all information posssible for your SYSYEM, SPECIFICATIONS, BIOS, Some of this will help you, Find manufacturer information and Download BIOS from the manufacturer, (OF SYSTEM, MOTHERBOARD and from MANUFACTURER OF THE CHIP BIOS.Preferable in DOS versions, they will boot right away in your computer,but you have to be informed in the steps to follow to FLASH your BIOS, Google for PDF files for tour SYSTEM, MOTHERBOARD and BIOS MANUFACTURER, understand the process to follow.THIS applies to any system, laptop or desktop. this is the safe way, BUT if this not work try the DANGEROUS WAY. HACK it, RESET it, FLASH IT, CRACK IT, BACK up IT, or simply remove the chip of the motherboard and put a new one, SOmetimes people crazy think that if you put the system of and no battery, inside of extreme temperatures will erase the bios, it is NOT TRUE. If you have no luck we will try to find a way.ALWAYS

Hi mate, try removing all power sources, i.e. main power lead, main battery, bios battery, then press the power button for about 10 seconds to remove any residual charge on the motherboard. Apologies if you have already done this. If not update and flash to new bios... download here for your OS...
