    P15 Gen 1 (type 20ST, 20SU) Laptop (ThinkPad) - Type 20ST need main and video BIOS

    P15 Gen 1 (type 20ST, 20SU) Laptop (ThinkPad) - Type 20ST needs the main BIOS and video. The client says that after the Windows updates there was a firmware update and after that the device makes the sound of music when there is no screen. Moreover, if you turn it on several times then the picture sometimes appears and it works and passes all tests (wonder)
    and may even reboot normally a couple of times
    Now he doesn't want it anymore, no matter what I tried
    It helped to change the video cable a couple of times, I ordered a new cable, it didn't help
    Of course I checked the fuses and installed the screen

            Fixed: Lenovo P14s Gen 1 (type 20Y1, 20Y2) Laptop (ThinkPad) bricked by a withdrawn BIOS update (r1buj82w)
            by akwky
            Hi!
            Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).

            Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...

            M715q Desktop (ThinkCentre) - Type 10M3 - Request bios chip location and useable bios for use with CH341A Programmer.
            by hotcrossedbuns999
            My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
            1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
            2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
            3. I could only locate two chips that look like bios chips. Could someone verify this

            Lenovo ThinkPad L15 G3 Bios 1 IC conductor track
            by 1g0r
            Hello everyone,

            First, the data in brief:
            Manufacturer: Lenovo
            Model: ThinkPad L15 G3 21C3-0016GE
            motherboard: LG4 LT5 ADL RT UMA MB 8L - 448.0PZ26.0011
            IC Bios 1: MX77L25650F
            IC Bios 2​: MX25L25673G
            EC Chip: NPCX997KAABX

            So far I've been a silent reader, but now I need your help

            I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
            I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele...
            The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge

            🛠️ 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
            ...

            Should I buy a Lenovo Thinkpad E495 with bios password?
            by RMDUiFT
            Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

            I have a few questions:
