Why does computer CMOS battery just drains out after a few days?

I would have to say that there is something bad in the circuitry of your motherboard. I would contact the manufacturer to see if you can get your mobo replaced because a CMOS battery should not do this.

Then something is on pulling power from the battery. Check all lights and relays.

If I had to guess I would say you have a short in the electrical system that slowly drains the battery as it sits.

How can you reset the BIOS password and unlock a computer?
If it's a desktop PC, erasing the cmos memory will usually clear it. Turn the power off, remove the cover. There should be a battery, these days they use a large silver disc watch battery type. Near it should be three pins with a linker on two of them. Move it to the other side, so the middle pin is linked to the other pin. Leave it there for a few seconds and then put it back in it's original position. Replace the covers and boot up. You will then have to reset your BIOS options etc.. On Laptops, they all most always write the password to EEROM or flash memory, which don't need a battery. Unfortunately, sometimes the only way to clear these, is to remove the chip and use a programmer to load it with the latest BIOS from the manufacturer or replace it with a new one. Dell computers have a master password which is unique to each computer. That password can be obtained from Dell customer service.

I'm just passing through...my '99 sonoma would drain battery after 2-3 days. Clock did not stay on but alternator had a short inside that sucked up the juice. Does your alt light come on when running? Just a suggestion, check alternator. G/L
What should you do if you have forgotten your BIOS password?
Do this carefully, and before touching anything inside your computer case, touch the metal outside of the case to discharge any static that might have built up. Look inside for the cmos battery, and there should be a jumper in the general proximity. Some motherboards you just need to pull it off and move it over a little and then move it back. Some, you need to move it over and turn the computer on and then put it back. Try both, and it should work.-Lamaboy
