Secondhand HP Laptop, don't know the Bios password.

[Barryw1953]

hi, have just bought a Pavilion 10TS of the net and the previous owner doesn't know the Bios password.

I have had a few tries using obvious passwords but no joy and have the 8 digit code from the lockout screen, 38445237,

can anyone help with the response password please. I tried the code generator but to no avail.

Here's hoping one of you guys might be able to help.

Thanks in advance.

Hi,

thanks for the quick reply but no joy, comes back with "Invalid Password", 😞

Hi,

You're welcome

In that case, check the following.

1.  The halt code ( generated after 3 incorrect entries ) that you've posted is definetely correct.

2. Shut down the notebook, unplug the AC Adapter and then remove the battery.  Hold  down the Power button for 30 seconds.  Plug in the AC Adapter ( leave the battery out for the moment ), start the notebook and try entering the code again.

3.  Try entering the code via an external usb QWERTY keyboard.

hi,

Still no joy, used an external keyboard and left it off for a couple of minutes but still says "Invalid Code"

I checked the fault code and it was [i 38445237]

Thanks.

Hi again,

got to pop out for 15 minutes so don't think I'm ignoring you.

Back soon.

Hi,

The unlock code for the checksum you've posted is correct - the only other option would be to hope that the code isn't stored in nvram, so it's worth removing the rtc cell, then hold down the power button for 60 seconds, leave the machine like this for a couple of hours before re-inserting the rtc.

Oh well, that's me busy for a while, these HP 10's are a pain to disassemble.

I was hoping to avoid this but I suppose it's time to bite the bullet and crack on with it.

many thanks for your help. If I get it sorted I'll update the thread.

Hi

silly question time, as the RTC battery is on the underside of the motherboard and it means removing everthing from inside the chassis to get to it, should I just remove the battery and leave it for an hour or so, or do I need to remove the battery and put everything back together then press the power button ?

Then take everything back out and replace the battery and reassemble?

The person who designed this is obviously an idiot !!
