Motherboard battery

[Lalakai]

Okay, a quick and easy one. I need to replace the battery on my motherboard; should I do this while the system is on or off??? Sounds simple I know, but looked in my manual and nothing, plus considered that by removing the battery while the system is off may result in CMOS data being flushed. Any help would be appreciated. Thanks

OFF!

The system should be OFF and UNPLUGGED from the wall. Also, after you unplug it from the wall, hit the power button on the front of the case. This will drain any residual voltage in the PS.

Removing the battery WILL clear out the CMOS. You will have to go in and reset everything. If you're not real sure what to adjust all the settings to, after you set the clock, there's a setting in there called "load optimized settings." Hit that, hit F10 to save and reboot and you're in business.

Good luck.

thanks guy for the help.

was hoping for an easy way out, but looks like I still have to go through the meat grinder. Have to reset several of the default settings, to disable an onboard sound card, plus manually set some irq's. guess I'll have to record the settings first then load up on the patience. thanks again.

Everyone consider this: How can you change the motherboard battery with the system is on????????

Can you go to the sun if it is at night?????

You cannot swap out the motherboard battery w/the mobo powered-up. At best you'll get sparks, at worst you will fry the motherboard and everything attached to it.

I have no idea what you're talking about w/the sun and moon thing...where's that bunny pic?

Some mobos will retain their bios settings for about 30 seconds without a battery, giving you time to put in a new one if you are prepared and dextrerous.

Alright, successful operation; only had to dip into my supply of "chicken's teeth" a little. Up and running, plus it gave me the chance to clean up some bs that was cluttering the system, so hopefully alot of problems will be cleaned up.

as for the 30 second window, just ain't possible for a guy with sausage fingers, working next to delicate circuits and wiring. Heck, count myself lucky that I finished and the power came on when I toggled the switch. gotta take the little victories when they come.

thanks again folks.

Current....perhaps. ) Voltage is just a potential...
