If this issue started with a motherboard error that appeared to be a faulty CMOS battery and then it started incorrectly detecting your memory and now is asking for a password it could be a faulty motherboard. If you are 110% you or anyone else has set a password on that laptop then I would say your motherboard needs to be replaced. It is a difficult process to reset admin passwords on most laptops due to a security chip that will prevent the trick of removing the battery from working. In all honestly if no one has set a password and the motherboard THINKS someone has then even if you reset the password you will still have issues. There is a small chance your CPU or RAM could be defective. But, again going back to it saying you have a password set that was never set. It just yells faulty motherboard unless someone has set a password without you knowing.

You may need to contact the manufacturer to reset the BIOS password.
If you can find the service manual of the computer, it may have
instructions for resetting the password. It may involve taking the
computer apart and shorting a couple of pins together. Service centers
may have a special part, which when connected to the computer, will
cause the password to be reset.

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
