3.6V CMOS Battery

post #1 of 3
Thread Starter 
For a while now I've been having a problem with my hard drives losing communication with the computer, all of the sudden all read/writes come to a halt which often leads to data corruption, me needing to reinstall Windows, and me raging.

I've tried installing Windows to 3 different drives and the problem has occurred with each. Usually my solution is to replace the CMOS battery which hopefully fixes the disk read error and allows me to boot/install the OS. I don't know why this works but I've gone through about 30 CR2032 3.0V CMOS batteries in the last couple years. I assume the problem is with my motherboard, but I don't want to replace it yet since I have no money and would rather just wait to build a whole new rig.

I'm wondering if i can start using 3.6V CMOS batteries which are rechargeable. The idea comes from needing to replace CMOS batteries so often, perhaps they're being drained fast and dropping in voltage.

That is odd... my understanding of the BIOS voltage supply was the battery was only required to ensure settings were retained when the mainboard was powered down, I guess if your board is screwy anyway why not do a higher capacity hack? I'm thinking of something like THIS with a cradle mounted in your case somewhere, 900mAh will outlast the button cell's 40mAh significantly!


Pity it's out of warranty or an RMA would be in order, have you contacted DFI over the issue? I had Uniden (communications company) replace equipment that was years out of warranty due to product faults they couldn't define OR repair...


EDIT: this issue kinda' sounds like a mainboard short, had you removed and/or altered anything immediately prior to this issue arising?

cmos battery should last about 10 years
its only used to save bios settings while the power supply is off

bios should have a voltage page that shows the current psu and battery voltages

make sure the sata and power connectors on the drives are secure

also check the board and case for possible shorts
ex. lose wires, metal flakes, unmounted screws ect..
