    Lenovo LOQ 15 APH8 (7840H, 4060) BIOS chips not detected

    Problem: Soft Bricked Laptop, Lenovo LOQ 15(Geekpro G5000) 7840H, 4060

    Background: After adjusting the Advanced BIOS options (Fn+R+N) and accidentally changing settings about RAM & Graphics, pressed F10 (Save & Exit), then Blank(Blank) screen, led power lights on - soft bricked occured.

    Goal:To reset the BIOS Chip/s to be able to boot back to the machine

    Attempted:
    I tried to dump and reflash a BIOS file with CH431A clip on:
    winbond
    25Q16JWIQ 2309 6222 DGA400ZX
    winbond
    25R256JWEQ 2239 6236 M0022

    Results: Chip not detected

    I also tried to do the BIOS Crisis recovery method (Fn+R on startup), but the laptop seem not to read the bios file (7zip: extracted ILG50039.ROM file from LYCN39WW.exe). The charging light turns amber and led power lights turn off, then simply restarts back to blank screen.

    Regarding the Crisis recovery, I am not sure if I got the correct file and renamed it properly. I read on other forums that this method will not work if the file is not renamed correctly. I tried to rename the ILG50039.ROM file to "LYCrisis.bin", "LYCN.bin", "ILG50039.ROM", "ILG50039.bin" but nothing changed.

    I also tried to use "ISpillMyDrink/UEFITool" to extract further the "ILG50039.ROM" file and renamed it to the above file names to no avail.

    Are the any programmers or softwares that can detect the above BIOS chips?
    Also, are there any other ways to flash/reset the bios to revive the laptop?


    I hope that you can give me any advice moving forward on other things I can do to try to revive this bricked laptop? Thank you.

      1.1.1.6. CH341A
      Supports I2C (24-series), SPI (25-series).

      This programmer is not recommended but it is the cheapest programmer available.
      It has several shortcomings:
      Limited interfaces support, only SPI and I2C
      Several different software with varying level of reliability and ROM IC support (especially troublesome with 128Mb and larger ICs)
      Several different hardware design, some of them having design defects
      No proper detection of communication issue with the ROM IC

      Available software include: NeoProgrammer, Colibri, AsProgrammer, Flashrom…
      Read the guide there: https://winraid.level1techs.com/t/gu...rammer/32948/3

      If you have a black PCB, it is very likely that it needs to be modified for 3V operation instead of 5V. Failing to do so could damage the ROM IC.
      Watch the instructions there:

              ASUS TP500LA BIOS request/repair/merge?
              by jbonavita
              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...

              [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
              by zenius
              Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

              Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

              HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
              by Bloodhoundje
              Hi everyone,

              I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

              I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

              After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

              I have desoldered the bios chip (GigaDevice...

              Acer AN515-52 SATA1 port not working no hdd detected in BIOS...
              by titomno2
              Hi guys,
              On motherboard ACER AN515-52 type LAF951P.
              I fixed issue with not starting computer (it was the PQ201 component not working properly).
              But after checking everything I have still an issue with secondary SATA connector JHD1 (for HDD typically).
              Basically some HDD spin but are not detected by the bios.

              ​

              Already tried following:
              checked the 4 data lines
              #2 RDSATA_PTX_C_DRX_P4 => CO18 (10nF seems OK) => RO24 (0Ohm measured at 0.25Ohms).
              #3 RDSATA_PTX_C_DRX_N4 => CO17 (9.68nF seems OK) => RO23 (0Ohm measured...
