Title: GA-H81M-S2H: Forgotten BIOS Password
Post by: Gebrix97 on September 09, 2017, 07:56:15 pm
I've sat up a BIOS Password (only for Setup) on my H81M-S2H, but I've forgot it, and when I tried to enter the Setup, I realized that I forgot the password I've used, ran out of 3 tries quickly.

Then I searched for methods for resetting the BIOS other than the generic "take out the CMOS battery" method, I took out the computer's power cord and I searched for the CLR_CMOS header, but I didn't found it, just the schematic on the PCB where its spot would be.
Under the schematic I've found 2 chips, right where the schematic's arrows were pointing, so I went ahead for the generic method.

After removing the battery, then reinserting it after 10 minutes, I powered up the computer, it started up, and after like 2-3 seconds, it restarted itself and asked for the password.

Now there is where I've got stuck. Now every time I switch on the computer, it prompts me to enter the password I forgot.

What should I do now?

If you have the board above, see pg 12 of your manual...  Item #14.  Remove power, leave battery installed.  Short the CL_CMOS jumper.

Ah, I found the header just above the Front Panel header. It's pretty hideous.

Actually it's a bit to the left off the Front Panel. Check the schematics ON the board. When I get my phone back I'll post a photo.
