HP ProBook 450 G7

[CarMagician]

Hello,
I have a HP ProBook 450 G7 which is caught in a bootloop.
SKU: 3C0889ES#ABD
I can't even access BIOS. Tested RAM and SSD on other system and even applied working parts from other system.

It starts, I see the HP logo, can press ESC, F1 and all other possibilities to do something, it wants me to insert password, I enter the correct password and it boots over.
I guess there is something corrupt on the two BIOS chips.

1. winbond 25Q128JVSIQ 2002
2. AJ2001 25B127DSIG UAF845

On the HP website nothing is available anymore.
Can somebody provide the *.bin files for the chips?

Thank and greets
CarMagician

Re: HP ProBook 450 G7

I have a password that I have to enter when booting.
I know the correct one, but if it has to be removed it would be no problem.

The password is not the problem - the bootloop is the problem.
And I can't even access the BIOS.

Re: HP ProBook 450 G7

Thank you.
Password is indeed gone!
But it is still bootlooping, it says entering bios but then it does a reboot instead of entering bios.

SO THE PASSWORD LOCK WAS NOT THE ACTUAL ISSUE

ISSUE IS IN THE BIOS

Re: HP ProBook 450 G7

Can you specify which of the chips is MAIN and which one is EC?

[CarMagician]

Re: HP ProBook 450 G7

Okay, nevermind!
I used Winbond as main and the other one as EC.
I see a BIOS now!!!
Will reinstall now and test.
