186621 2003-10-26 02:04:00 Hi my friend has a Compaq Presario 7400 about 4-5 years old and the time and date keeps going back in time many years. I think it's the R.T.C battery, she only has the computer on for 5 minutes a day to clear mail then removes power plug from wall. What I want to know does the computer have to be running to charge the battery or by leaving the power on at the wall and computer off would it still charge the battery?

Hope some one can help. Thanks Mick.

186622 2003-10-26 02:09:00 If it's 4-5 years old, the "battery" will be a 3V lithium cell;. :D And it's not charged. A new one is indicated. Usually a CR2032, (a shiny metal disc about the size of a sixpence in a holder).

Be careful with the clip holding it in the holder ... it's easier to break that than to fix it.

Some OS's support it natively, some need extra software...

Computer clocks are bad for keeping time even without a dodgy battery...

186628 2003-10-26 11:08:00 The battery is on the Motherboard, inside the main case of the computer .
The Motherboard is the ~300mm square~ printed circuit board that everything connects to . 3 years is not unusual for a battery to last .
The battery will be quite visible in a flat holder, hiding in the most awkward place .

There will only be one thing that looks like the battery, it should be labelled CR2032 or similar .

New batteries are available at your supermarket battery stand, and are about $3 - $4 .
Or pay $6 at an electronics store for the same thing .

The battery looks like This ( . dse . co . nz/cgi-bin/dse . storefront/3f9baa5206cff588273fc0a87f99074d/Product/View/S3331" target="_blank">www . dse . co . nz)
These links have a habit of only working for a day, so dont curse if the battery isnt displayed . Worked on the day .

186629 2003-10-26 14:24:00 I must say that my present PC with an MSI MB has had a very reliable clock. It has only been adjusted by 0.17 seconds after about three months. using Dimension4 mikebartnz (21)
