It's had trouble turning on, and the time has gone funny.
This is going to sound stupid, but I can't see the battery! I am an utter computer illiterate though.
I think the motherboard id is acpi\pnp0c02
There's a big fan mounted on to it, and I thought it could be under that. As I said though, I'm an utter novice here, and removing the fan looks like a mighty task... am I likely to ruin something while I do so? Is there any other way I could save my PC? Is there an easy way to check what battery I should be replacing, just so I can make sure I've got the right sort here when I go (google has let me down)?
Any advice would be greatly appreciated. Quite likely advice on buying a new desktop will soon be needed too.
