Good day
I have a laptop that will not boot I have to remove the cmos battery for a min then put it back in and reboot then I get the above message and sometimes can press enter to boot into windows. Once there I have to change my date and Im ok until I shut off my laptop. I have tried to flash the bios with an update but still same problem. I was thinking of trying to replace the bios chip on the MB.

Before that replace the CMOS battery with a verified new one.
