    I have a Lenovo Thinkpad T470 with a now damaged tamper protection switch. I can't access the system BIOS to disable the error message as the unit hangs at the error (and then displays a perfectly blank screen when I press the ESC key). SN:PF11JCWY TYPE 20JM

    I have tried to patch my bios to remove the supervisor password by unsoldering the bios chip (MX25L12873F)and plugged into ch341b programmer. After patching the bios chip with Lenovo_autopatcher_0.2 and programmed with CH341A Programmer software, I resoldered the bios chip on my T470 (20JN) motherboard and tried to power on the laptop, but unfortunately, now the laptop is not booting, nothing is shown on the display. I tried to program back with the original bios file but of no use, nothing is showing on the display. When I press the power button, the LED on the button does not glow. But when the power adaptor is connected then the LED on the power button glows and flashes for 3 times and than goes off. Can anyone tell me what to do now and how to fix the problem. I'll be very thankful and grateful to him. I have attached the original_BIOS file that i have saved before erasing the chip to program the patched_BIOS.

    Hi,

    I tried to use the Autopatcher for the T470 BIOS, and I can no longer boot, even when flashing from my original dump.
    I have used Neoprogrammer for Windows and IMSProg for Linux. Both times, I was unable to get to POST. I will be including four images from all the backups I took.
    I'd appreciate if anyone could at least point me in the right direction to recover my BIOS.

    Parts Information
    Model: T470 Type 20HE-CT01WW
    MB Part No.: CT470 nm-a931 rev 2.0
    Serial No.: PF-0RLX6M
    PCB Marking: CT470 20B2
    Processor: i7-7200U

    🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
    by macabook
    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

    by NielsTH
    Hi forum members.
    I hope you can help me with the next issue.
    I've got an old Asus K75V (K75VJ) laptop, that I updated to Windows11.
    The upgrade itself was succesfull, but had trouble installing new security updates.
    After a lot of Windows troubleshooting and no success, I took a look at the Asus support site and found new Bios version.
    K75VJ - Support
    When downloading the bios update, the name of the download was "K45VMAS233", and made me causious and doubtful.
    When I opened the Bios and loaded the file, I checked the current version and the...

    Dell Latitude 5530 BIOS Password Removal Attempted but I Broke the Laptop
    by TopPop
    Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.

    I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip...
