1376042 2014-05-27 22:08:00 I have a P4SD motherboard
the bios has a password that the owner doesn't know
the motherboard has a tiny yellow button that says CMOS next to it.
I have researched but unable to find ~ how to reset the cmos
to erase the bios password.

any suggestions?

1376044 2014-05-27 22:37:00 yep tried that ~ no go (left it out for approx 15 min)

1376045 2014-05-27 22:45:00 See if something similar to this is on the mobo.

Turn it off first / unplug it

Move the jumper leave it there for 5-10mins. Then put it back to where it was

Then reconnect it then see if you can get into the BIOS. If you can you'll have to reconfigure the BIOS settings

:waughh:

Seriously tho, turn off the PC, push the button

or turn off pc, unplug power supply cable, remove the battery next to the button.
Go make a cupa tea , come back & you should be all erased.

Remember to reset the time & date !!!

1376050 2014-05-27 23:12:00 Only mobo I can find is this HP one (h10025.www1.hp.com). But the battery is on the other side to your pic Speedy Gonzales (78)
1376051 2014-05-27 23:15:00 wish there was a red button!

I left the cmos battery out for 30 minutes
pushed the button with & without power

still wants a password to enter bios
When booting it shows HP D530 SFF?
