A friend of mine approached me asking about his CMOS battery, because he said he had an error message pop up saying that it was about to die.

He wants to know if it is of that great importance to replace it. I told him that really the only thing it does is supply power to the machine when it is off in order to keep date and time properties correct. Am I correct here?

Is it important to replace it? and is it any easy swap/where can I buy a replacement battery?

thankyou!

batteries are standard replacement parts and they do keep the bios settings in programmable memory

replace it but often with a custom build machine there will special settings to re enter

where can I buy a new battery? Radio Shack? Walmart? and I'm assuming its as easy to replace as say a battery in a watch?

Radio Shack, Circuit City, Best Buy, and yes even Wal Mart.
If in doubt about what you need, take the current battery out. Either take it with you OR write down any info on the battery. Those things are really cheap, easy to take out and install.
Been there, done that with a dead CMOS battery-only I got no warning.

Replace it Immediately! Not only will you lose any custom settings, but if your system time and date are incorrect you will not be able to run windows updates. Normally the cmos battery is a CR2032
The name says it all -- 59 and holding permanently

okay so an update in my problem. my friends battery ended up dying. he moved his computer, and it had died. so he replaced the battery, and now the computer is all sorts of screwed up.

it seems that they have to reinstall windows entirely, but they don't want to lose their files. we've brought windows up in safe mode to save important documents to a disk.

but is there anything to do to save all information on the hard drive, or can we go without reinstalling windows?

You can try a repair install if you have XP or 2000 Pro, Win2000 Repair install Windows XP Repair Install.

You can also start up using the {F8} method, like going into safe mode, but select last known good configuration. If there is malware on this computer, you will still have problems with it.

i told them to go into the last known good configuration, but apparently that didn't work.

the computer was perfectly fine before the CMOS Battery died. they called gateway, and they said to just replace it. So they buy a new one, and replace it. when the turn the computer back on, everything seems to have gone awry.

Did they reset the time in the BIOS once the new battery was put in? If not, this can cause all sorts of problems with Windows and the programs that it runs.

I agree, like I WARNED BEFORE, clearing cmos without knowing about bios settings is playing russian roulette

Gateway should have warned them also

Some of the older oem's just need to be booted into bios and then save settings, even when you add ram

FWIW - we had an issue at work the other day due to this. Some of our diagnostics expire on a regular basis - and this PC was insisting that the diagnostic had expired. We fussed with it for quite a while until we thought to check the date on the PC - sure enough, it was wrong. Correcting the date solved all of our problems!

When clearing the CMOS, you can also get an inproper CPU Speed...I'd just check it as a safter precaution.

My husband has a laptop HP Pavillion ze4400 that needs that battery replaced. Does anyone have any idea where it would be on the laptop?
Thx,
Heidi
