299189 2004-12-02 21:15:00 i would be inclined to have a quick look through the bios settings to see what there are set to before removing battery.

simply resetting back to default may result in a slow pc or features missing (sound, usb etc). bios may have a 'performance' default setting which is often better. also there are a few mobo's which if reset to default can stuff the data on the hardrive (due to defaulting to incorrect settings), thankfully theres not many of those.

i would take note of the settings and set the bios back up after changing the battery.

If you don't hear from me again, you'll know I followed the wrong advice!

299191 2004-12-02 21:23:00 You could always go into the comos setup and copy every thing down.

Change the battery, any method listed above will work.

Go back into the setup and check all the settings again.

You have to be careful what OFF switch you're referring to.
On ATX pcs the front panel and software on/off still leave some power on the motherboard. If you start using tools etc who knows what might be shorted.

Also has OP determined that the battery is user replaceable and not soldered?

what harm ?

harm to me :D

It just that when I did my training I was taught and have sinced practised that when working on anything with a mains supply always make sure it is unplugged. Yes I know that the power supply reduces 240 down to 12 or 5 volt but Im not going to take a risk and as stated earlier it against my training.
Susan and Billy looks like we will just have to agree to disagree on this one guys. :D

299194 2004-12-02 22:45:00 Unplugged will do no harm. Just load "optimised defaults" after the switch IF the settings are lost. george12 (7)
299195 2004-12-02 22:46:00 Of course, remember that there are capacitors, so if you do the switch fast enough (less than 30 seconds or so) it might even remember the settings :) george12 (7)

Yes . I should have said the switch on the wall needs to be off .

Fair enough, Beama .

Well I am not going to argue with those with training/qualifications and far more experience than I so I will just have to decide which is the lesser of the two evils I guess . :-)

299197 2004-12-02 23:04:00 A very good point, PaulD: "Also has OP determined that the battery is user replaceable and not soldered?"


No, I have not; only because the m/c is in a cabinet that I shall have to drag away from a wall, then remove its back to get at the old girl, before I can even start the process. I plan to do that on Sunday.
