"Enter Power-On Password" Issue

[AlexGuerrero]

Dear HP,

This morning my desktop booted prompting "Enter Power On Password" for no reason (maybe a power black out overnight?). I do not have that password.

Quick Facts:

1) HP Slimline 260-a020 Desktop PC

2) Windows 10

3) Requesting "Enter Power On password" at booting.

4) We haven't done anything special to the computer, only usual Windows updates.

5) I have tried the solution of removing the case and removing the CMRS battery + holding power button for 20 secs to restart from scratch but it did not work. 

6) I can provide the serial number for the computer if that helps you generate the relevant "Power On" password.

Looking forward for your help, as our business depends on this computer to be operational!

When asked for the password, just hit enter 3 times.

Post any code you receive.

Thank you for the prompt response!

I did that three times and instead the last icon is a big *    ... but no code?

Not sure if you move the blue or the black jumper???

I would try to move the black one up first.

Then power-on for a few seconds.

If it is not that one try moving the blue one to the left.

Let me know what you find.

Hi, just saw this reply. Thanks for this elaborated response!

(1) I do not think I moved the jumper at all. I just took off the CMRS battery, held power button for 20 secs and put back the battery. In restarting, the date was off (from 2018 it went to 2011) but still prompting for the BIOS. 

(2) I am going to open the machine again and follow your visual instructions in this answer

Thanks a lot, it worked!!!

(1) I tried first moving the black jumper -- nothing happened

(2) then i moved the blue jumper one step to the left (i.e. to the middle position) and restarted the computer

(3) I got first a message that the CMOS configuration was erroneous and it was going to be automatically fixed to the right settings and immediately after Windows started normally.

Thanks thanks thanks! Your help made my day!
