    lenovo s145-15api, black screeen after BIOS update

    hi guys!

    can you help me? I have a problem with my lenovo s145-15api. I did a BIOS update but now the machine doesn't want to display an image. It won't start.
    When I press the power button, it lights up and stays lit.

    I tried to recover it by saving the bios.cap file on a flash drive, connected it to the notebook and pressed fn+b; fn+r but it didn't work.

    Lenovo IdeaPas S145-14API
    Model Name: 81V7
    M0: PE9039C20132
    MTM: 81V70004BR
    S/N: PE05BNYP

    If there is a way to do this recovery using a flash drive it would be better. But if necessary I have a ch341.

    Thank you very much!

      Read the rules before posting.
      You must post in an existing thread.
      You must provide the bios backup.
      Sorry there's no lazy method tho dump the bios, so grab the programmer and read the rules.

                                      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...

                                      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

                                      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...
