CMOS battery replacement HP All-in-one 200-5120

[Taart]

I need to replace the CMOS battery of my aunt's HP All-in-one 200-5120, but when I opened it up I didn't see the battery on the visible part of the motherboard. Does anyone know where it is on the motherboard and how I can reach it without breaking anything? I'm afraid something will snap and I will break the entire pc.

on the motherboard should be by the card reader slot and plug in ports on the mother board. do you have the motherboard model number?

Are you sure you need to replace it?

It's pretty rare that I hear about someone replacing the CMOS battery.

If you can change a BIOS setting, SAVE it, then reboot into the BIOS and the setting was changed then the battery is working fine.

DIFFERENT LAYOUT, but it demonstrates how to take apart the PC.

*So the battery may be hidden and require you to take off screws, panels etc to get at. Again though, I'd be surprised if you needed to.

It should be the 2AA2 motherboard.

Yes, I'm pretty sure its the battery, because everytime she starts up the computer the time is back to the same date in 2010 and it takes a lot of time for the computer to start up, with the screen saying that the bios is starting anew (or something like that, I have no idea how to describe it in English :s)

Okay, it does sound like the battery.
