As is known to all that BIOS password can be used to stop someone powering up a computer system or making changes in some of the computers most sensitive areas. Setting a bios password is necessary. However, when you forgot bios password and you need to access the BIOS, what should you do? Take the most used Dell laptop for example, here are some methods to reset dell bios password. Method 1: By Removing the CMOS Battery The simplest way to reset dell bios password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget a lot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware. Anyway, open up the computer case using a screw driver and locate the flat, circular and metallic CMOS battery. Once you have located it, observe how the latches are holding it. Make sure to power down the computer, unplug the power cables and unplug any USB devices if they are powered. The computer must not be able to get power from anywhere for this to work. Take out the CMOS battery and wait 10 – 25 minutes before putting it back in. The reason for this wait is because the computer can still store power in its capacitors even though everything is unplugged. The waiting period allows enough time for them to discharge. Plug everything back in, power up the computer and enter the BIOS again. If everything went well there should be no more password. In some cases, if you get weird error messages during bootup now, you will need to goto “Load BIOS Defaults” in BIOS and save the changes to fix them. If this method didn’t work, try one of the methods below. Method 2: By using the manufacturer backdoor password On many computers (especially old ones), computer manufacturers build in backdoor passwords for their own technicians to use so they can access the BIOS when the hardware is being serviced. Here are some of the ones that have been reported. You may need to try quite a few passwords before you find one that works Method 3: By using Software PC CMOS Cleaner is a free BIOS password recovery and removal utility tool, for computers running Microsoft’s operating systems.
