computer clock loosing time

fortyaday

Anybody out there know why the clock on my 'puter looses time.Iread an article that said there's a battery on the motherboard that maintains the clock.Anybody know anything about these.i.e.Type/ease of replacement.(I'm assuming if it's on the motherboard it's probably soldered to it) Any help/advice on this would be greatfully appreciated.

This one should be easy,

pop the side off your case (you may need to unscrew the back, also don't do this if you have warranty on it).

Next take a look at the motherboard and you'll see a round silver disk like an only camera or watch battery.

This is the battery which needs replacing. You should be able to read what it is without removing it so you can get a replacement and swap them over.

Make sure you are touching an unpainted part of your case before touching anything else inside as this will ground you and protect against static. Also of course make sure the computer is unplugged.

if it is connected to the net, set it to automatically sync, and it shouldn't be a problem, but they are usually 3V CR2032 or 3032 watch batteries, available for a couple of quid, +/- 1.50, depending where you buy them from

If it is exact hours out, check your timezone.

Agreed - CMOS replacement

Opening a computer shouldn't void its warranty. PCs are full of user replaceable parts.

How does touching an unpainted part of the case ground you if the computer is not plugged in?

Opening a branded computer (eg Dell) inside its warranty will almost certainly void said warranty.

Also apologies I meant unpowered i.e turn the power supply off.

Dell won't cover any "damage caused by incorrect installation, use, modifications or repair by any unauthorised 3rd party or yourself" (Apple is the same), but opening the case doesn't void the warranty. Computers are user-serviceable.

That's better.

(Does that mean that I void the warranty by (correctly) installing additional DDR RAM? Or is "damage" required before the void is effected?)

Anyway, I had the same problem a while back, and in my case, it was the computer battery (as others have suggested) at fault. But it was a very easy repair job and I have had no problems since... Fingers crossed!

It means that if you try to change the RAM and you accidentally break something, then the warranty won't cover its repair.

That's fair enough.

Excuse me but...

Why is everybody automatically assuming that this newbie OP has a Windows PC?

At what point has he/she ever indicated that the computer involved is not a Mac?

The OP mentioned a motherboard...

I heard that Macs operated some kind of magic box instead; elves and pixies and whatnot - not a motherboard in sight!

Bigotry indeed.

(More likely that the computer clock on a Mac doesn't run down, alas...)

Fortyaday,

Welcome to the MSE forum. You are most welcome.


Everybody else,

Nowhere.

Presumption and bigotry rules in this forum.

Think about it. :cool:

Did anyone give any advice which is not applicable to Macs?
