How to bypass your bios password
A bios password prevents access to the bios for unauthorized users, and while it does a good job at keeping users out, it should not be taken as a 100% secure protection from attacks. Sometimes, you may also run into issues after having set up a password to protect the computer's bios. You may have forgotten the password, or it may have been set by an ex-employee who no longer works in the company.
Theguide "how to bypass your bios password" explains in detail how you can bypass the bios password or remove it altogether to start anew. So, if you are in need, take a look and try the available methods.
Update: The website the article was originally published on is no longer available on the Internet. As with every website that is taken offline, its contents also end up in nirvana with little chance to access them again once the website has been offline for some time.
Thankfully though you find many other resources that provide you with information, guides and tips on how to bypass motherboard BIOS passwords.
- Elfqrin offers standard BIOS backdoor passwords that users can try first to see if it is enough to get into the BIOS admin interface again. If that does not work, the site suggests to flash the BIOS using software or hardware to regain access again.
- Technibble offers instructions of their own. Their tip is to remove the CMOS battery of the BIOS to make the BIOS "forget" its settings as it is then without a power source that is keeping the information available. The guide is also offering BIOS backdoor passwords for several motherboard vendors and OEMS that may be worth a try.
- Tech FAQ more or less rehashes what the other two resources have already mentioned in their guides. You may find additional Bios makers mentioned in the guide though which you may find useful if the passwords offered by the two other resources are not giving you access to the computer's BIOS.
I suggest you check those guides out instead as they can help you bypass the password of a Bios in case the password is not known anymore.Advertisement
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.
