Hi !
I initialy tried to unlock password from an HP Elitebook 835 G7 by extracting and updating the lower side Bios (replacing the NvramActiveRegn areas with 0xFF Hex Area at adress range 37000-38FF0) ; it worked quite well for removing the password. However after, I am getting a error message when booting stating "Endpoint Security Controller Problem".
From various posts on this forum and youtube I understand in such cases that I have to reprogram not one but the 2 bios eeprom chips. However I could find no clear method for fixing the upper bios chip. Furthermore, people seem to say I sould have an uppder 16Mb chip and lower 32Mb chip, but on my laptop I have two 32 Mb chips with different contents, uploaded here.
(please note I also tried the RCUnlocker software, but had no luck trying to run it, experiencing the infamous "application was unable to start correcly" including after tryind to whatever software dependency the woftware needed...).
Can someone help me with fixing my bios or point me to a valid method on how to fix the upper chip as well ?
Thank you very much in advance if anyone can help

Hello,
I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)... -
Hello everybody!
To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.
The thing is that I had installed TeamViewer and could log into the computer...
