Re: HP ProBook 450 G7

HP ProBook 450 G7 Schematic
Hello guys,

Especially where EC and Main BIOS Chip are located.
Thank you very much! -
Re: HP ProBook 450 G7
Can you specify which of the chips is MAIN and which one is EC?Leave a comment:

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.Leave a comment:

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.Last edited by CarMagician; 06-30-2023, 02:59 AM.Leave a comment:

HP ProBook 450 G7
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 [B]25Q128JVSIQ [/B]2002
2. AJ2001 [B]25B127DSIG [/B]UAF845
On the HP website nothing... -

Re: RCUnlocker
Hello, I downloaded the tool, and it says unlocked.
But there are no files created inside the directory, maybe I am dumb?Leave a comment:
