Re: pls Bios HP Probook 450 G5
I bought a used Laptop. Unfortunately BIOS setup is secured by password, but I need to enable Virtualization Technology (VTx) & Virtualization Technology for Directed I/O (VTd) on my Laptop.
Automatic BIOS Update Setting are disabled
Update BIOS via Network is enabled (but needs still pw)
Legacy Support is disabled and Secure Boot is enable (suckz also)
I've no idea how to change BIOS settings without the Admin password. Also I can't boot any native cracker software (tools included in Hirens or Kali for eexample), because secure boot Option.
So I'm looking for a possibility to flash BIOS without extracting the Chip from Board, because I don't have the hardware ans the knowledge to flash the EEPROM and I'm also not good in disassembling and assembling microelectronics, but didn't found any alternative solution till now.
Maybe u've an idea?Last edited by macl; 08-23-2022, 10:07 AM.Comment

Re: pls Bios HP Probook 450 G5
Get yourself a cheap Ch341a programmer, less than US10, with clip preferably. program it with asprogrammer. Take out the CMOS battery if it has one. Identify your BIOS Chip, usually it reads Windbond or MX and has lettering like W25Q128FV. Read and save first reading, close programmer and start again, do a second read and save. Again close program, unhook everything and start again, do the third read and save. Download WINHEX, a hex editor, and compare your saved readings, two at a time. They should all be identical, otherwise, do some more readings and pray to the internet gods you got it all right. Remember that is your backup in case something goes bad. Rar or Zip the bin file you got and post it here, someone will help you.
I myself rely on the TL866II medium priced, and a 200mm adapter for legged chips and a double WSON adapter, 8X6 and 6X4 for legless chips.Comment

Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

I'm requesting a bios .bin for 2 of my hp Probook 450 G3's. Both of which I had forgotten the bios passwords. I stupidly flashed both of them with firmware "made" by the RCUnlocker software and I guess I shouldn't have. The last thing I did was flash both of them with RCUnlocker-fw thinking it would 100% work and left my programmer etc behind and won't have access to them for another 2 days so I figured I'd create a thread to see if I'd be so lucky that someone might have a working file laying around 😝

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
