HP nx6110 BIOS password

[ Edited ]

I have an HP nx6110 with a power-on BIOS password. I have followed the maintenance instructions as listed in the service guide to remove the password. I have left the RTC battery disconnected for a number of days before applying power (mains only, no battery or RTC battery). However, the BIOS password still remains.

Does anyone have any further suggestions? The unit is out of warranty with HP. Is this a known 'bug'? Does anyone have a working motherboard from unit that is otherwise faulty that they could send me?

Re: HP nx6110 BIOS password

This unit has a BIOS power-on password,
BIOS "admin" password (to block specific changes) and DriveLock passwords.

I thought removing the battery would reset the
first two. Are you sure it's the power-on
BIOS password and not a DriveLock password
that's causing the issue?

Yes, I'm sure it's a Power-On Password. See attached photo. I've tried booting without the hard disk and it fails with the same error.

Re: HP nx6110 BIOS password

That's clearly the power-on password :-)

The procedure in the docs differs
slightly from your description:
- unplug from mains
- remove laptop battery
- remote real-time clock (CMOS) battery.
- wait 5 minutes
- replace the RTC battery and then
plug in - without the laptop battery.
The laptop battery cannot be present
when you remove the RTC battery
and shouldn't be there when you power on.

Re: HP nx6110 BIOS password

Peter,
Thanks for your quick response. I have completed the process EXACTLY as you indicated - ensuring the battery is disconnected before removing the RTC battery connection, and ensuring that the battery is not replaced when reconnecting the RTC battery and applying mains power only.

Any more ideas?

Re: HP nx6110 BIOS password

Hi Arnold, i have the same problem. To cancel Bios password, i pressed enter and saved. Namely, i used blank. But when i open pc, it still asks Power-on Password. Did you have solved your problem? What should I do? What is the cause of problem?

Re: HP nx6110 BIOS password

Hi Pierrot Robert,
I've the same problem, too with HP nx6110 with a power-on BIOS password.
I removed both the normal battery and the RTC battery, but the BIOS password still remains.

- unplug from mains
- remove laptop battery
- remote real-time clock (CMOS) battery.
- wait 5 minutes
- replace the RTC battery and then
plug in - without the laptop battery.

Does not work :(

Also the procedure for forcing the floppy (WIN+B on startup) is not working...

Tnx
