Need instructions to take laptop apart to replace bios battery, my laptop is losing time and i think it needs replaced. Can someone tell me how to locate the battery?

My Compaq nc6220 is losing time, so I think the bios battery needs changed. I was able to find the battery in my dell desktop when that one was dying, but I have no idea how to find it on this laptop. It doesnt give instructions in the user manual.

Look in section 6.3 for dissasemly instructions on how to take apart the laptop.

Then go to page 6-51 of the service manual and it shows you a picture of the BIOS Battery as it looks to be in the top cover.

Please tell me master password key for power-on password of hp compaq nc6220.i have already tried to remove bios battery but i can not remove my power-on password


You would have to perform this in the BIOS ( Basic Input/Output System) Here are the steps:

1. Restart your computer. 2. Enter the BIOS by pressing the designated key (usually F1, F2, or Delete key).You will be able to enter the BIOS by pressing any of those keys..(this is the black screen that appears before your window starts up) 3. Inside BIOS, navigate the "menu" option by using the "arrow keys" 4. Search for "user password,system password, or power-on password" as it may vary depending to your system. It should show you "enabled or Active" and you have an option to "disable it" 5. Make the "disable password" press enter. 6. Click the "Save Changes" or "Save Changes and Exit" option in the system and it should not ask you for a password the next time you turn your computer on.
---for your reference, the command help is shown at the bottom of the BIOS screen which will guide you which keys to use while navigating inside it.

How do I clear the BIOS on my s6500NX? Usually this is done with a jumper change and battery removal on a Dell. Not sure how this one works.


The other way is to remove the BIOS battery and let it stand for 20 plus minutes, then insert the BIOS battery back into the computer. The BIOS settings will then be returned to the factory default settings, you then need to go into the BIOS setting and change the Date and Time setting.

My Compaq nc6220 only starts up when the ac adaptor is plugged in. I think the battery needs to be replaced. does this sound right ?


To check if the battery is charging go to Control Panel - Power Options - Power meter. If it shows unknown or zero charge then the battery is faulty or worn out. Rechargeable batteries have only a finite amount of charge and discharge cycles and over a couple of years use they lose their full amp hour charge capacity.
