Howto reset EEPROM motherboard password that I forgot over 18x months ago?


I have a Gigabyte Motherboard - cannot see any model # - on a computer I bought ~ 5-6 years ago. I last successfully entered password over 18x months ago...now forgotten... Howto reset EEPROM password? Any advice gratefully accepted!

Pull the small battery off the motherboard, and wait a few minutes. Should then 'forget' things, and go back to defaults. First, though, look at the manual for your motherboard, because some boards have a dip switch/jumper setting specifically designated to reset BIOS to defaults.

A Gigabyte motherboard should have a "Clear CMOS" jumper.

Back in my hardware days, I used to remove the battery, then touch the (springy) positive lead against the negative pcb area for the battery, which was 0V. It seemed to work, and saved me reading .

Some MBs have a soldered battery because it's cheaper to manufacture.

Might want to be aware of that and see if there is a clear CMOS capability avaliable.

I don't think I've ever seen a soldered battery on a Gigabyte, or on any PC motherboard made since Y2K.

The soldering temp would be pretty lethal to things anyhow, whether done by hand or solder wave.
