Any amateur computer technician should know how to reset BIOS password because there are times when they need to access the BIOS and change some configuration such as boot order. The old school way of resetting BIOS password is by taking out the battery from the motherboard
and let it sit for 5 minutes, then put it back and power it on. If you read the motherboard manual, they will tell you to switch the jumper to reset all CMOS settings. When it comes to HP computers, it is very different. I’ve tried taking out the battery and left it for a day but still the BIOS doesn’t get reset. There is no CMOS reset jumper on the motherboard as well. From the CMOS itself, you can even configure it to lock the casing and the BIOS access password has an extra security where it will be completely locked out if you specified 5 consecutive wrong password.
Now, if I don’t set BIOS password, some student will. If I set it, the student will try to brute force it and end up locking the BIOS completely. The only way is to call HP support center, wait for their technicians to come and clear the password for you. If the computer is within the warranty period, then there will be no charges but if the warranty is over, we’ll have to end up paying for it. I recently discovered a free tool that can be used to reset BIOS password from Windows.
CMOS De-Animator is a service utility which allows you to invalidate the checksum of your system’s CMOS memory, resetting all settings to default and clearing any stored BIOS passwords (if any) upon re-boot. There is no graphical user interface and all you need to do is just run the executable file. You will only get confirmation message to begin or exit, error handling messages and a success dialog box upon successful operation. There are 2 versions, the 32bit and 64bit so make sure you use the correct version according to your Windows operating system.
Although it did mention that no administrator privileges is required, but you may want to run it as administrator if the BIOS password did not get reset. I’ve tried it on my Dell 1909 all-in-one computer and it worked perfectly. Both the supervisor password and user password has been cleared leaving me able to access the BIOS without entering any password. I am not sure if CMOS De-Animator will work on HP computers or not because I currently do not have access them but I will update once I’ve tested it.
NOTE: Some antivirus flags this tool as a threat (trojan, malware, dropper, downloader) since this tool is capable of bypassing password protected BIOS. I am not surprised at all and am confident that they are false alarm. You should not even download it if you always listen to your antivirus.
