Hello,
There are 2 ways you can reset your biosHave an Acer Aspire 4520 laptop that is bios - 2_bing.gif.

1. On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in2_bing.gif your system. Your reset is now complete

2. Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and 3. Your reset is now complete


This is a great troubleshooting2_bing.gif step for those of you having POST issues or no POSTing at all. Like other troubleshooting steps, this will not always work but usually will depending on the problem.

Please let me know if you have any further questions or concerns.
Thanks.

My acer aspire 4520 is asking for a bios password and i've never had one.so needless to say i cant operate my computer.is there anyway to get through this??


As a laptop repair tech I encounter this problem frequently and I use www.unlockbiosrecovery.com to give me the bios master password which clears any bios password set. They charge $20 and guarantee it to work. I use them couple times a month and it has always worked.

Hi

if you just want to reset a user password go into control panel users find your account and set a password

if its a bios password i believe you have to do it in the bios by pressing delete or F2 on startup but be very carefull not to alter other settings in the bios

I lost bios password of acer aspire 4520


Hi,

If you have forgot BIOS password then you have to reset CMOS jumper setting. Please follow the below steps: Open the Laptop back panel. Locate the CMOS battrey, remove it & then with the help of a screw driver keep on pressing the terminal inside it and turn ON the computer for 10 secs and Turn Off (make sure you keep on pressing the terminal with a screwdriver while turning ON). It will clear the BIOS setting. Now, fix the CMOS battrey & restart the computer. This will take care of the issue.

Thanks and regards,
Jitha
