Hello Millano,

 

Take a look at this documentation on your error.

HP and Compaq Desktop PCs - Error: CMOS Checksum Bad | HP® Customer Support

 

Let me know if this helps.

Dear Photoray002,

But ,I did everything....and I have always the same problem...

So you're saying you have replaced the cmos battery as the article suggested and it still has the error?

 

Is your tablet still under warranty?

If so, you need to contact HP Support for warranty issues.

Contact HP Worldwide | HP® Official Site

Millino, contact HP Support for a warranty issue.

Let them see what needs to be done.

OK if that is the case, here is the link to the PDF file from HP for taking apart the X2 210.

HP Pavilion x2 Detachable Notebook PCHP x2 210 G1 Tablet Maintenance and Service Guide

 

Although I did not find specific instruction's for removal of a cmos battery for that model, I found similar info for another X2 12 that should give you the general idea.

Remove and Replace the Real Time Clock Battery on the HP Pavilion x2 Detachable 12-b000 Notebook | H...

 

I will add that you do this type of task at your own risk.

 

Hope it helps.
