              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,...

              Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
              by Wahaz
              Hello,

              I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
              So I thought it was a Bios problem.
              I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

              Macbook pro 13 A1708 Low voltage on bios chip
              by Marek011
              Hi, While trying to unsolder the BIOS chip, I accidentally blew out the R6130 capacitor and now I'm wondering what kind of capacitor it is because I don't know which one to buy. Getting to the point. The Mac draws 20v and 0.330A and does not turn on, it is dead. On pin 8 of the BIOS chip (U6100), the meter shows only 1v and then drops to 0v. After connecting the USB tester to the board itself (with all ribbons disconnected), the board consumes 5V and 0.024A

              Where could the problem be?​
