Hi All,

I have a HP 440 G10 with a bios admin passsword which I would like to remove. I have tried the rex98 files in post 43 (both main and EC) but after install all I see is a flashing caps lock (no image, nothing else). I have also tried just the BIOS (reverting EC back to the original) but this also does not work.

Please could someone help me remove the Bios admin password? I have posted the original backups below:

Serial - 5CD40132ZTF
Prod - 717Q4AV
Model - HP Probook 440 G10

I have now tried manually removing the values from "NvramActive" section but that also has not worked. Anyone please help?

rex98 files should work, try again and check soldering. You have to wait 3-5 minutes until you'll get image, it will make a bios update (downgrade, infact) and then enter in mpm. Press F10 and reset bios factory defaults then use BCU to write your DMI.

volinakis - thank you very much. My soldering was excellent... however, my patience was terrible 😁 I waited longer this time and after 3 minutes, the files worked like a charm!

rex98 - thank you for the files, really apprecaite it

Hello,
I'm following this thread with interest because I bought one of their PCs, an HP 440 G10, from a company. Unfortunately, it's neither formatted nor accessible (it has a Windows password and a BIOS password).
I'm stuck: while disassembling and reassembling PCs isn't an issue for me, soldering is a major obstacle. I paid €250 for this computer, and I'm quite disappointed at the thought of having lost that money.
I've seen methods online talking about short-circuiting the chip with tweezers or similar, by choosing the right pins. However, I have no idea how to identify the correct ones. Do you know?
Are there any solder-free solutions to resolve this problem? Or should I just accept that I've lost €250 and my time, and simply throw the PC away?


Bonjour,
Je suis ce fil de discussion avec intérêt car j'ai acheté à une entreprise un de leurs PC, un HP 440 G10. Malheureusement, il n'est ni formaté, ni accessible (il y a un mot de passe Windows et un mot de passe BIOS).
Je me retrouve bloqué : si démonter et remonter des PC ne me pose aucun problème, la soudure est un obstacle majeur pour moi. J'ai payé cet ordinateur 250 €, et je suis assez déçu à l'idée d'avoir perdu cette somme.
J'ai vu sur internet des méthodes parlant de court-circuiter la puce avec une pince à épiler ou autre, en choisissant les bonnes bornes. Cependant, je ne sais pas du tout comment identifier les bonnes bornes. Sauriez-vous me renseigner ?
Existe-t-il des solutions sans soudure pour résoudre ce problème ? Ou dois-je me résigner à avoir perdu 250 € et du temps, et simplement jeter le PC ?

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Thanks for your reply.
Can I get a low-end SPI programmer like this one (https://a.aliexpress.com/_mtez5hp)?
Do I need to solder the BIOS chip's pins onto this programmer? And if so, which pin goes to which point? I'm trying to understand. If I see it's too complicated for me, I'll give up.
Thanks again.

Merci pour ta réponse.
Un programmateur SPI, je peux en prendre un bas de gamme comme celui-ci (https://a.aliexpress.com/_mtez5hp) ?
Il faut que je soude les broches de la puce BIOS sur ce programmateur ? Et si oui, quelle broche va sur quel point ? J'essaie de comprendre. Si je vois que c'est trop compliqué pour moi, je laisserai tomber.
Merci encore.

Better you choose a RT809F + a hot air.
You can find many videos at youtube explain how : justtype some words key like
Desolder bios , how to use rt809 , how to read bios ..etc..
