Whenever the power is cut off and comes back on my computer restarts on it's own and resets the bios to default which is no problem but always having to setup the clock in F10 is tiring. I replaced the CMOS battery. Could I have bought a bad battery?
First run bios update program
change new brand battery
if your system is laptop check adapter & main battery
else desktop cross check new smps
if smps problem power off system restart

Turn the laptop upside down and then you'll see it's bottom!:P Alright now you can see two sides that can be unscrewed.The one that is to the opposite side of the cd drive is the one that can really be unscrewed.The other one has more screws that are covered.So,unscrew the side I said before and then you'll be seeing the battery the ram cards and some other stuff I don't know what they are.:P Now look closely to the opposite side of the battery and under the metal case.Somewhere there in the dark is your battery lying and waiting for you!I hope I 've helped you enough!

hi
you will need to open your computer and look inside. if you are not sure take to a repair centre, the battery is on the motherboard, thats why you need to take really if you are going to be doing it. But i would advised to get a IT guy to do it for you. once its taken out you need to replace it with a new one.

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.
