Has anyone got experience of and good advice on changing a computer motherboard battery, please, something I have never done.
My computer is a 5 years old HP Pavilion a6355.uk, which on switch-on is showing the wrong time, which I believe is the first symptom of a dying battery. I was away over the weekend, and this morning even the date was wrong!
As soon as I mention this to people I start to hear stories of the BIOS losing all its settings as soon as the old battery is out - when anybody mentions the BIOS as far as I am concerned "There be Dragons", due to total unfamiliarity I suppose.
On the other hand on the HP help webpage, under issues causing the computer to fail to start, I found
Real time Clock Error
Windows should still be able to be opened by pressing F2 after this message, but the time and date will be incorrect and should be reset. The battery for back up has most likely run out of power. Just like a battery on a watch, the computer has a battery on the motherboard to back up time and settings when the computer is off. Remove and replace the CMOS battery and then correct the time to prevent this error from occurring.
No mention of the possibility of the BIOS setting being upset.
Does anybody have any views, please?
Many thanks,
Andy
