Power on password

Ok, I give up.  Anybody know how to get past this annoyance?? HP Compaq d530 SFF, I can't get past this "Power On Password" on boot up.  NO, I don't know the password.  Clearing CMOS doesn't help...because..??   Thanx for your help....

Re: Power on password



I believe the Omni is a Business class machine? No backdoor passwords on Business machines.Only Hp Service can remove it.

Re: Power on password



CMOS will not remove the Power on Password. Instead reseat the CMOS jumper. CMOS jumper will be near the CMOS battery.


Hope this will help you.


Thank you.

Re: Power on password

No good,the cmos clear is just a momentary switch.  There must be someone out there who knows how to clear the non-volital memory.

Re: Power on password

Usually there is a clear power on password jumper near the clear cmos jumper on the motherboard.  You might look for that jumper.

Re: Power on password

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.


i already 

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...


all useless....

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.

Re: Power on password

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
