              Maybe its from EC , thats smells like a SERVICE MODE , 5 blinks then force fan and nothing - its try to resotore some data from EC and if its not posible goes to SERVICE MODE. Try to resolder chip and flash both BIOS and EC.
              I`ve got a BIG database of HP. - sorry no1 with AMD video...

                  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,...

                  by Soumana Sanou
                  Hello,šŸ˜‡šŸ˜‡šŸ˜‡
                  I need help unlocking the BIOS password on my HP ProBook 11 G2 laptop.

                  šŸ”§ Model: HP ProBook 11 G2
                  šŸ“¦ Serial Number: 8CG72478MY

                  The laptop is no longer under warranty and HP refused to help me.
                  Iā€™m looking for a custom SMC.bin file.

                  I don't have a CH341A programmer, so it's difficult for me to provide a BIOS file.

                  Thanks a lot for your help!šŸ™šŸ™šŸ™...

                  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....

                  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
