not as simple as u know...
my main board made on 2004
Model HP-Compaq dx6120
this model not used jumper.. they use button as reset.
1. Push CMOS reset button (with battery on it)
2. Push CMOS reset button (while in run mode)
3. Push CMOS reset button (while run mode.. but without battery)
4. Remove battery and power supply for 2 days...
it still ask for "Power On Password"
last think i got in mind is..
1. Flash the cmos but where can i get this flashing things
2. HP gave the default password, so we can reset it manually
3. Throw away those HP model and find another vendor for my office.. and never take this HP Desktop or Laptop...

Hi: @ Abengah80:
Here is the link to the troubleshooting guide for your PC:
See chapter 2 B for the procedure to clear the BIOS password.
It does use a jumper as do most of these older business desktop PC's. I own several of them so I know (d530, dc7100, dc7600). All have green jumpers to clear the BIOS password. Look by the green motherboard light. The green jumper should be near that area.

jumper is not always near the battery, on mine it was not close but was near the cmos area marked Cmos, I removed the jumper and restarted the computer and it booted up. I powered down and reinstalled the jumper and it still booted up
