HP 250 g5 administrator and power on password

[BogdanR]

My hp laptop when powered on boots up to the Administrator and Power on password display.

I have it for over 1 year and work ok. 2 days ago after shutdown when powered on it displays administrator password field and requiters a password. i did not set up any  password and what is curious that if i shut it down and power up many times 1of 10 it starts windows. but on next shutdown we start again.

I am now stuck with the System Disable message  Code [ i 51223169]

Is there anyway I can remove this power on password? (i have already tried to change the cmos battery and stayed with it removed 12h and no luck)

The CMOS battery on a laptop has NOTHING to do with any BIOS password -- as that is encrypted into the BIOS firmware on the device.

That is a Disable Code but we're not permitted to provide Disable Code bypasses anymore.

Passwords can NOT be recovered; instead, they have to be reset.

If your PC reset your password on you, we can not help in that because we have no access to either the original or the new password.

We are not permitted to assist in resetting passwords due to HP Policy.

To reset Admin passwords, you have to contact your regional HP Customer Support location directly for assistance.

BIOS and power-on passwords are contained in the firmware that is present inside the BIOS chips -- which are soldered to the motherboard and thus, are not replaceable. So, you can't just buy a replacement chip and swap them. Also, neither your nor HP can reset the BIOS password on the current motherboard. Thus, replacement of the motherboard is required with one that has a BIOS chip that does not have a password in the firmware. This is very expensive to do and can often cost more than simply replacing the PC

If you are not prepared to spend the money to get HP to replace the motherboard, you would have to take the PC to a local repair facility to see if they can do anything for you -- but we can not assist in that in any way.
