Hi. Got a Probook 6540b with a locked BIOS. Is there any way I can remove it?
I used the HPBR tool by Mazzif, it did not work tho.
Thanks

Re: HP ProBook 6540b BIOS locked
You could flash a new clean bios with a programmer (ch341a for example) -

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

hello friends - I have purchased a used Thinkpad X13 Gen 3 AMD variant and only after making the purchase I realised that the BIOS is locked. I have spent a bit of time browsing the forum and from what I understand it's possible the modify the BIOS that is currently on the machine and remove the password from that BIOS. For dumping the BIOS from the laptop I have ordered this ch341a programmer. Below is a photo of the password prompt:
I have taken the cover off the laptop and I found that "serial number" is "GM-0358MB" and "type number" is "21CN-S19U00".... -
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...
