HP Recommended
Product: 13-an1007na

I have a HP Pavilion - 13-an1007na that I have been trying to get work. It doesn't even seem to get to the bois. When I booted it the first time I got an error "CMOS Reset (502) The CMOS checksum is invalid" which asked for a reboot. I said yes to the reboot and then the screen went black. 

 

It now seems to turn on and the screen lights up for a second before going fully black again. If I leave it then it will keep repeating this forever with it lighting up for a second. No text shows after this. I think it is trying to check the bios and failing.

 

I have tried removing the battery and running it on just the charger but it has the same error.

This model doesn't appear to have a CMOS battery so I can't replace that and I don't have a replacement for the main battery.

 

Is there anything else that could be causing the issue?
