Call tech support and they will give you a recovery disk but it clears all files you saved but if you have this disk then you can use that or when you start up your computer it should say something like system recoveryf10 or something like that

Try removing the main battery and the CMOS battery (ie the battery on the mb). If you don't want to wait for 1/2 hour for the CMOS to discharge then short out the CMOS battery connections with a bent paper clip.
Then without instralling both battery, power up your laptop, you should then get into the BIOS, power off and re-install your batteries.

I had a acer company laptop model extensa 4620 . probbem a bios password and c; access dinied . bacause i am not remeber bios password. so ple, sowl my pro.


Hi there,
You can reset the bios password fairly easy. You will need to unplug the laptop from power and remove the battery pack. Then you will need to turn it around and you will see a cover plate. Remove the plarte and inside you will see a little flat battery. Just remove it and replace after 2-3 mins. Then close up and replace battery and restart. Should have cleared the bios.

Hope it helps

You have to pull the cmos battery from the board. It is the only way to reset the password. Some manufactures back a backdoor password they do not share with the public though. Only real way to is to pull that battery.

Hi,

im sorry to hear that but unfortunately, if youre not the one who created the BIOS password, theres no way for you t acces it anymore, what you can do is to reseat the CMOS battey on the motherboard so that BIOS password will be reset.


Hope this will help...

I want to reset bios password.


what you need to do is to remove the CMOS BATTERY for some seconds/minutes and then replace it. This brings your machine to default settings and then you can enter a new bios password.start your computer then press F10 for setup/Delete for other machines and then go to bios settings and set a new bios password.In addition to this you can also clear the bios password by removing the shunt on the cmos jumper then plug it other way round, remove it again and then plug it as it was at first.

The computer locked and I can not unlock because it won't let me type inn my password. no letters appear when I type. Acer extensa 4620-4431


For security reasons, some laptops do not show passwords when you type them on the password page.
For your own case however, I would suggest that you should just try and reset the Laptop Password to its default settings by removing the CMOS battery. This means you might have to unscrew your laptop at the back, and try to locate the CMOS battery, remove it from a few seconds and replace it. This method will automatically reset your password to its factory settings.
If you cant unscrew your laptop by yourself, you can easily get a technician to do it for you.
Hope it helps you out.
Goodluck!
