I forgot to mention: I tried different BIOS versions, including "universal" ones with the Supervisor Password already removed for the T490s, but the laptop does not respond to the power button with them. Also, with the patched BIOS, the laptop emits short beeping sounds after some time. This version of the program is apparently no longer compatible with the T490s BIOS.
Therefore, I still require assistance with the BIOS modification. Thank you.

Hello,
I have a laptop with supervisor password as below:
Model: Thinkpad P50
Type: 20EQS3G11S
S/N: PC0ULEHX
BIOS chip: MX25L12873F
Story:
I tried as in the first page and also as in this video: https://youtu.be/ja2zptfgs3I
I read the original BIOS three times, compared them with HEX editor. They were OK.
Used auto patcher and auto patcher 0,2, in total three times did not help.
After the patched BIOS was written I clicked READ button, saved that and compare it with the patched BIOS using HEX editor, they were not the same. This happened for three times.
It was only black screen with 5+5 clicks. No boot. Then I returned back to the original BIOS and it works as before.
I attached original BIOS and the other BIOS files.
Could you please help me on this issue?
Thanks!Comment

Keep your original dump as is !
STEP 1: Flash and replace current BIOS with this patched file
STEP 2: Boot the machine
STEP 3: Press ENTER/F1/etc. to enter BIOS settings
STEP 4: Enter any character when asked for Supervisor Password
STEP 5: Press enter when it shows Hardware ID
STEP 6: Press space bar 2x when asked
STEP 7: Turn off machine
STEP 8: Restore original BIOS
STEP 9: Reset BIOS settings to factory defaultComment

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 everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -

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...
