Do you have the ch341a black edition,can you check the voltage and make sure it hasn`t got 5V on pin 28.You may need to modify it so it only uses 3.3V https://www.chucknemeth.com/usb-devi.../3v-ch341a-mod .Its possible to flash the EC with the ch341a you`ll need to solder wires to the JEC connector.
        ive done the mod, i read 3volts on all pins but still i cant read the EC chip for some reason.

        foto to mod:

        Im not 100% sure this is the IC chip, can u confirm ?

        Foto to connection EC:

        if i plug programmer into usb and quickly press read id. it reads id, but on reading nothing. writing nothing

        battery is disconnected / power plug disconnected/ motherboard battery disconnected

        Thanks!

          Check the part number on top of the chip, then do a google search with that part number to make sure it is a bios chip. Look in the schematic as well,search for SPI .

            Thanks for ur answer once again, i have got the schematic
            But if i press ctrl+f and type SPI. i can only find the 128mbit ( 25b128cs1g )
            i cant seem to find the EC in the schematics ?

            if i check the other chips under the microscope i can see 2 chips with 80,
            25q80csig.
            (https://datasheet4u.com/share_search...Word=25Q80cSIG)

            and on another location at the motherboard 25q80dvsig.
            ( https://www.datasheetq.com/datasheet...ond/25Q80DVSIG )

            the one where i tried to read and flash is the 25q80csig.

              The GD25B128C is the bios chip. Notice the Mb ,the capital M means Mega,and the lower case b means bits. Divide 128 by 8 to get 16.Its 16MB ,with a capital B for bytes, MegaBytes.

              https://cdn.badcaps-static.com/pdfs/...75588d6e59.pdf


              GD25B128C 128Mb 2.7V-3.6V 128Mb = 16MB .Bits and bytes are all confusing.

                Re: alienware 15 r3 La-D751p bios fix

                haha alright i might have figured it out 25q80dvsig is the one i can read and write. i saved the original and flashed the 1.8 now on it including bios 1.8 on the bios chip. il test now and report back

                  See post #18 posted a few moments before yours. If you made a backup of 25q80dvsig flash it back and leave it well alone.The bios chip in the schematic doesn`t always match with the part number on the board,U4 is the bios chip W25Q128FVSIQ in the schematic.

                  The 25q80 chips are for the thunderbolt firmware and gpu bios .

                    yes but i was looking for the EC chip. i believe i found it 25q80dvsig

                        with just the bios flash the laptop gives 2 red lights, 1 blue.

                          I said at post #11 the EC can only be flashed through the JEC connector. Whatever you just flashed i hope you made a backup, flash the backup back onto it and leave it alone.Just flash the 16MB bios to the 128 16MB bios chip the GD25B128CSIG

                                  Hello! Can anyone help me by chance. I updated both my alienware 15 r3 and alienware 17 r4 with the 1.4 bios a while back and it broke my intel me which in turn, now my usbs don't work and my pc will not shut down unless held power button. I tried to flash both bios files linked in this thread but no prevail. They both result in 2 red flash followed by 1 blue flash. I reflashed my original backup and now im back where I began. I have done the 3.3v mod also. Any help would be highly appreciated!

                                            Greetings badcaps community,

                                            I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
                                            So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.

                                            Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.

                                            I have a Elitebook 820 G1 and a Elitebook 840 G2 here.

                                            These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

                                            Alienware Aurora R15 accidentally flashed with XPS 8960 BIOS
                                            by drux
                                            Hi,
                                            I've had an ssd that was previously used on dell xps 8960 and then it was installed in Alienware Aurora R15(intel version). On first windows boot in R15 windows started bios update and loaded bios for xps 8960(r15 and xps8960 essentially have same motherboards).

                                            Now it has xps 8960 bios that looks different from alienware bios and when I'm trying to run bios update files for R15, I get unsupported platform error.

                                            These models have AMI/Aptio BIOS.

                                            Tried to edit product info with DMI Edit to change values back to Alienware R15, but it does not want...

                                            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
                                            ...

                                            looking for a fully extracted (by programmer) Bios for a Dell Inspiron 17 (7786) v.1.09 or newer, so I can compare it with my own bios to check for corruption.
                                            cheers
