cmos HP Pavilion x2 Detachable

Product Name: HP Pavilion x2 Detachable
Operating System: Microsoft Windows 10 (64-bit)

My device is 3 months old and I recently updated the BIOS through the HP assistant and am now receiving an error message close to


'CMOS checksum value is invalid. System will reboot with default values. Please check BIOS to see if any changes have occured (as close as I can remember)'


System then boots OK. I am wondering what is causing this. Is the battery already dying?


This has now happened three times in a week and also the clock is reseting itself to 05:00 everytime.

This is NOT official HP Customer Support and I, as most other persons on this forum, do not work for HP. This is a peer-to-peer user supported forum for HP products. HP maintains no official presence on this forum and it is unlikely that HP will respond in an official capacity. Any reply from a HP employee represents their own opinion and not that of HP's.


When requesting assistance, please provide the complete model name and product number (p/n) of the HP computer in question. HP/Compaq makes thousands of models of computers. Without this information it may be difficult or impossible to assist you in resolving your issue.


The above requested information can be found on the bottom of your computer, inside the battery compartment or on the startup BIOS screen. Please see How Do I Find My Model Number or Product Number? for more assistance locating this information. DO NOT include your serial number. Please enter the model/product information into HP's Online Consumer Support page and post it here for our review.

While it is possible that the battery is "dying" already, there is also a possibility that the CMOS is faulty.


I am sorry that you are having issues with your computer. I have forwarded your concerns to the HP Forum Administrators for possible escalation. Please watch for a PM (private message) from an HP Representative on this forum.

Re: cmos HP Pavilion x2 Detachable

The problem did not go away completely. It still happens on rare occasions. It seems to happen when the laptop doesn't shut down properly and I close the lid. If I wait until the light has gone out on the side (with charger out) it seems ok. I never just close the lid. When it does this error it recovers without issue so I've decided to put up with it.
