The device turns off

Gentlemen HP
Thank you for providing the best services in the field of smart devices and we as 
customers do not contact only the parent company HP
When I was young, the first device I got was made by HP and when I arrived
in the prep, my father gave me HP as well. When I arrived at the university, I bought
an HP device. All of them were working well, With my last exhaustion, which I got from
work. It's an elitebook 8560p. It works fine for a year and at the moment I have
a problem. I switched the CMOS battery and from that time the device works for only
a minute and a half exactly and turns off. When I disconnect the CMOS battery, the
device works well all day. I'm using the device without the CMOS battery. Time and 
date alarms and Bios settings change after the device turns off more than once I hope
to find a solution to my problem, thank you for your cooperation in advance and I hope
after God that you will solve my problem
Greetings to you with all the friendliness and love
