          Thank you for replying, yes I tried to flash it and after it didn't work I tried a few more times, accidentally erased it and the backup got lost on a wipe, careless on my part, After I read it, since it was erased, it showed all FFFFs, I have a I am using AsProgrammer version 2.0.4, I wanted to get another working bios to flash it and have it running as it was before.

              Really started now (PW07TSR2) 03.2024 you won't find a BIOS for this unless someone would download something like that from their notebook.
              What was the reason for reading the BIOS with this bad CH341A junk?

                Onsite warranty for 3 years. Hmmm

                  I bought it from a girl in FB maktplc, she advertised as "it turns on but locked, for spare parts" it was an unlock project, it is locked still, but it will not turn on because I found out , after reading many threads, I screwed with the programming in the PC dontroller chip, I had some free time and I thought it would be a good way to spend it, but project is not going well at all. I guess I have to wait and see if anyone has same model and is willing to upload a dump of the EC chip

                    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....

                    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

                    🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
                    by macabook
                    Hello everyone,

                    I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
                    🧩 Initial Issue
                    • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
                    • External display (HDMI) shows
                    ...
