Acer Aspire 3650 BIOS Password Reset/Recovery

[hotwired007]

hi,

 

when i started my new job i got given an acer aspire 3560 laptops to use as my laptop...

 

i'm being restricted by the fact i can get into bios and change some of the settings...

 

the previous tech says he didn't put a password on it... so therefore doesn't know what it is...

 

does anyone know how to reset the password or even know if there is a way a BIOS password could have been installed with a piece of software or something?

 

thanks in advance

I recently pulled apart 2 broken Acers to make one good one. Its not to hard just take your time with it. You can do that and pull out the battery on the motherboard for a few mins, that will sort it.

[hotwired007]

any ideas where the battery is? i thought it might have been soldered onto the motherboard... i've had laptops like that before... replacement was always fun!

I can't remember sorry. It’s my day off today, in the office we have an Acer Aspire 3000 series in bits i can check tomorrow for you.

Most acer laptops have a way to flash the bios in 'crisis mode'. If you go onto the acer support website and download the dos based flash update in the readme file it should tell you how to do a crisis update of the bios.

Acer Aspire 1800 I had with the same problem fitted with new BIOS Security chips I think I paid 65.00 for bios password removal

[hotwired007]

tried the backdoor keys... will try the crisis thingy...

[hotwired007]

no luck with the BIOS updates... wouldn't accept anuything i could download... although i've managed to download esettings that gives me access to the BIOS password from windows...

[hotwired007]

YAY! I fixed it

 

Although it does say everywhere not to use it i rread a couple of posts that it worked on...

 

cmospwd /k

 

it worked on mine!

A. By Using the Motherboard Jumper:

 

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

 

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

 

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

 

Make sure to turn the PC off before opening the cabinet and resetting the jumper.

 

 

 

B. By Using Software:

 

 

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:

BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

I have never ever seen a laptop motherboard with a jumper on it to reset the bios this is only normally found on normal boards.

This method to clear the jumper settings worked for me. Thanks very much for the info.
