bios password

By okippiko ·
I'm trying to help a friend with a computer problem. I want to access their bios to edit it, but it is password protected and they don't know what the password is. How do I bypass the password prompt to enter the bios? Any help will be appreciated. Thanks.

bios password

by avachon In reply to bios password

hi, the most common thing to do is to open up the box and locate the cmos battery (coin shaped; looks like a large watch battery, and it's close to the cmos rom chip on the board. Remove the battery (carefully and protect your system from ESD damage)and let the system sit for awhile (the power will drain out of the cmos chip and user settings will be lost such as password). Depending on the system, this may be a board that simply allows you to change a jumper setting to clear cmos (check the board documentation or go to the board's website - and you also could call the manufacturer since some sites aren't exactly clear or set up logically. There also are password cracking utilities you can download from the web. You can run a search on "password cracking" for example or someone else may know the better sites and utilties. I'd exhaust the obvious and simpler options first - board manufacturer and jumper settings first - and use the battery removal option only if other possibilities don't pan out. Hope this helps. good luck.

If the friend has the manufacturer handbook to the motherboard it will be helpful in locating a jumper close to the CPU that holds CMOS password,some boards mark the jumper with a white area,removing the jumper will allow you to reset the CMOS password.
Removing the battery will require that you have the system configuration available.

Hi, I Had the same problem myself after a lightning strike, nearly wiped out one of our servers. BIOS was a mess, and it appears that the system returned to "Default" settings. We were using a Intel R440-LX-DP motherboard with dual pentiums. On thatboard, the default password was a null string.

In other words, when you are booting, and you go into setup, in the password field, put in a space and hit return.

Maybe won't work for everyone, but hey, give it a try, what have you got to lose.?

Otherwise, the guys are right, take out the battery and wait 30 minutes, and start from the beginning and re-build BIOS.

Regards

You may be able to find the jumper settings from the manufacturer. There are three ways to do it without a password. Most boards have a password disable jumper and a clear cmos jumper. clear cmos is USUALLY right next to the battery. If you do have to remove the battery it can take a while to clear, it might not be good advice, but I usually boot once with no battery to speed up the process. I'm sure this can have side effects but usually not necessary because of other two methods.

On most bios you bypass the password by holding down the "END" key while you press the power button on the computer when you start the computer.
If this dosnt work you will have to open the box and either use a jumper to reset the cmos or remove the battery for long enough to reset the cmos.
