    Lenovo M90q Gen 4 Problem Bios crash update

    Hello,

    I have a Lenovo M90Q Gen 4, with Intel 13500.

    Yesterday, the BIOS was updated to the latest version, and for some reason, the process failed. Now, the computer displays nothing on the screen, and approximately 20 seconds after turning on, it immediately shuts down again.

    I tried copying the USB BIOS from Lenovo's website to a FAT32 USB drive and setting the motherboard jumper to CMOS mode (pins 2 and 4), even though the manual indicates maintenance mode, but I haven't found any jumper with that name.

    When I insert the USB drive and set the CMOS mode jumper (pins 2 and 4), the computer turns on, makes no sound, and after 20 seconds, it shuts down again (nothing is displayed on the screen).

    Can anyone help me revive this paperweight?

    Thanks in advance.

      Fixed: Lenovo P14s Gen 1 (type 20Y1, 20Y2) Laptop (ThinkPad) bricked by a withdrawn BIOS update (r1buj82w)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...

      Dell 9010 MT BIOS Update Always Fails
      by mikeybass
      Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...

      Lenovo M92p TINY 3238 lost ability to boot after BIOS update
      by keropi
      Hello!
      yesterday I received from eBay a Lenovo M92p TINY model 3238 system with 4GB of RAM and a 500GB mechanical HDD.
      I tested it and it worked fine, it booted to a fresh Win10 x64 French OS .
      The plan was to replace the mechanical HDD with an SDD one and upgrade RAM to the max 16GB since I had 2x 8GB SODIMM modules.

      I noticed that there was an update on the Lenovo support site so I thought I'd do that first and then proceed with the upgrades and installation of new OS.
      The windows BIOS update completed successfully and the system booted to a bios-like...
