Computer Clock Always Wrong?
« on: May 29, 2009, 04:53:28 PM »

Hi all,

My Dad's computer is now 3years old.

However, the clock is always the wrong time. I sync it with the Time online however it looses it again overnight.

Is it time I replaced the battery on the motherboard? How can I find out? No messages come up at boot so...

What I can't understand though is that my computer is nearly five years old and (touch wood) I am yet to replace the battery on the Mobo, and its on more than my Dads!

Any help most appreciated  :)

Thanks in advance

Jamie

As mentioned above, it is probably the motherboard battery.
The first signs are losing time, then you lose the cmos settings such as the boot order and when it really gets bad, you will get checksum errors during bootup.

How long they last for..............I guess its down to quality. Never had a battery fail with me and I have a spare computer that is nearly 10 years old.

Let us know if the problems persists after battery replacement.

If it is a CR2032 battery (very probable) you can get them anywhere (try the local market) and they are quite cheap.

Hi
@Jid  Make sure you have the new battery before you take out the old one . Just open up to check the number .

Sorted, will let you know how I get on  :)

I got a pack of 10 recently for 3.45 (delivered) via Amazon.
The seller was called Aquarius computers.  ;)
Cheaper than driving to Argos. 8)

If the old battery is very low, or some time elapses between removing the old one and putting the new one in, the BIOS settings may be lost altogether. If this happens, you'll probably get a message when you boot, saying that you have to go into the BIOS setup. It will then be set to its defaults, and you'll need to set the time and date, but probably nothing else.

Glad its sorted...

Errors with time setting on re-boot/boot-up are almost always the battery & its a fairly easy/cheap thing to try.

Some bios`s will flag an error about other stuff, depends on the settings & hardware.
