How to change time on BIOS Set up?

starlit · 25-11-2011 03:37PM #1

When booting up computer - windows xp operating system, BIOS asks to change the time. When I let the computer run and avoid setup utility to change it the clock on the the corner of the pc shows a different time on the clock and different date also. Its going back to August 2004! It worked fine the previous few days time and date was correct. Just that I changed the time and date on the clock last night manually but it didn't seem to alter those changes when booting the computer today.

So how do I change the date and time on the clock through the setup utility with BIOS? It won't let me in the date to change it, how do I change it through the set up? Anyone any idea? Wouldn't be all that familiar with the BIOS but have used it before for a few other issues.

It varies from machine to machine depending on the motherboard manufacturer and the implementation of BIOS used. What type of computer do you have?

If you're having problems with the system clock having been reset it's possible the battery on the motherboard has given up the ghost.

Hey got it sorted out myself. Ran the Command line and changed the date and time on it, rebooted computer and its clock is working -time and date as it is. Didn't go through the CMOS system just went from the command line run by MS-DOS.

Its a dell not sure of the model. Thanks for advice. Oh right thanks. Didn't realise the motherboard could be an issue I take note of it in future. The computer is over 7 years old. The Date was set at 26th of August 2004 so maybe that was the manufacturing date. Got the computer that Autumn. Have had same computer since 2004 but just had change the monitor a few times. So computer could be on the way out or just slowing down!?

If the computer is disconnected from the power supply then it will probably revert to 2004 again.
I have one old machine that does this because the battery on the motherboard isn't working and it's not worth changing it.

I had the same problem again this morning but managed to change the time and date from the CMOS utility. So far so good. I find if I restart the computer the time and date will be as it is now but when I turn off the computer and start it up again when booting up the BIOS still asks to change the date/time. Hopefully it will be ok in future. I'll reboot it again later and see.

Change your CMOS battery mate.

Thanks. Seemed to have worked better the second time I booted up computer today so seems back to normal. If it happens again I'll change the battery.

Still having the same problem. Sometimes it will ask to change the date/time when booting up other times it won't, have to change date and time on the MS-DOS command line. If I don't change the date at least, it won't let me into google or gmail or any website that didn't exist around 2004. So I change it.

Will look into changing the battery though.

Changing the battery is simple for most desktop PCs, it's a CR2032 battery and shouldn't cost more than a fiver.

This really annoys me , when you consider how little it costs to have them delivered to your door.

If you can wait a few weeks for (free) delivery

that wouldn't cover the stamp and envelope here.

and if that's too steep you could try a coupon

mod note - should really move to hardware since nothing to do with windows, alternatively to save your self the cost of the battery you could spend ages trying to setup NTP so the computer resets it's time regularly
