Remove the bottom cover of the laptop. The CMOS battery is a disc 3.2 volt li-on battery. replace it with the same voltage and size battery.

My HP Pavilion 515n pc will not restart without pressing the F2 key, why?


Message was "press F2 to continue". This happens when there are errors in the boot up process like:


CMOS settings incorrrect
Date/Time incorrect
Missing drive

First to replace should be the CMOS battery inside the computer.

My girlfriends Hp Pavilion A305W powers on then automatically powers off after it show a brief error message but also says F1 for startup. Should i press F1 and continue diagnosis?


Most probably your system is not getting your BIOS settings from your mainboard due to CMOS battery failure.

Check your CMOS 3.0v battery & replace it. Then reconfigure your BIOS settings from the CMOS setup.

Hope it helps

Reset BIOS on HP Pavilion a750w


Fastest way to reset BIOS is to remove the CMOS battery (looks like a large watch battery on Motherboard) for 30 minutes. After you replace the battery, the BIOS should reset to default. If further problems arise involving the BIOS, it's possible the CMOS battery is bad.

I beleive that error is the "realtime clock" error code. Most likely is the CMOS battery needs to be replaced.
