Replacing CMOS Battery in Laptop

Recommended Posts

So I have a custom laptop from PC Specialist and haven't really used it for a year since switching to a desktop. I got a  CMOS message saying:


"The CMOS battery is bad or was recently replaced. (If you continue is see the message, consult the system user's guide for more information.)" 


Press enter another message appears on screen:


"A first boot or NVRAM reset condition has been detected. (If you continue is see the message, consult the system user's guide for more information.)


Press enter again and it's followed by a 3rd message:


"The CMOS defaults were loaded. (If you continue is see the message, consult the system user's guide for more information.)"


So I did the usual things, remove the CMOS battery for 5 to 10 minutes, power off the system remove the CMOS battery power on the system then plug the CMOS battery back in.  Then remove the ram power on the system than reinstall the ram and power on the system. Nothing gets rid of these messages. 


But every time I boot it on I get these messages. 


I have also checked the systems user guide which has nothing in it about the CMOS apart from where it is located on the motherboard.


The laptop is a Clevo P775TM1 i7 8700k, GTX 1080m with 32gb Ram. 


Any ideas if I'm missing something. 


EDIT: Also if it help here is a link to the User & Service Manuel;

Did you replace the cmos battery?


FYI, there are no "custom laptops", at least not in this context. If you buy a laptop from a small vendor it's usually an MSI laptop. MSI makes tons of bare bones laptops for resellers. Clevo appears to be a similar brand to MSI. 


Can't say for sure that the plug will be the same, but I think most likely it will be: https://www.ebay.com/itm/174877692907?hash=item28b785d3eb:g:06kAAOSwwXRb5xgf


You can take a standard cmos battery and just pull apart the wrapping from the old one and reuse the wires for a new battery, then wrap it in electrical tape or something to hold the wires in place.

Replace your CMOS battery with a new one and see how that goes.  If its a special battery like the one UltraMega linked, just order one with the part number off the battery or off the laptop.  If its a regular CR2032, they sell those at every local jewelry place, including Walmart.

UltraMega is correct that its just the same CR2032's in those Dell examples and you can just replace the actual batteries inside the wiring harness.  But it is easier to just buy a new one with the wires already on it.
