  • Nothing special.  Power it off before removing the battery.  Just make sure you get the new one installed with the correct polarity.

    The Dell manual doesn't even show anything on it.

  • Thanks fireberd, I posted this question because as you say the Dell manual does not mention any instructions on replacing the CMOS battery.

    Will the BIOS settings be lost when replacing the battery? If so, should I take note of all the settings to be able to restore them afterwards? I read that even when the CMOS battery is removed, the mobo will keep the BIOS settings for about 15 minutes which is more than enough to place the new battery and not lose the BIOS config.

  • The BIOS will reset when the battery is removed.  If you have any custom settings in the BIOS, make a note of those so you can reset them after you are done.
