    Dell Latitude 5280 5THCBH2

    Hello guys,

    i got this laptop from a friend to solve a problem.
    The Laptop got a black screen. After turning it on, the keyboardlight is on and the fan working sometimes but nothing to see. The LCD is fine.
    I did the LCD selfttest.
    I think my friend tryed to update the Bios and failed.

    I have a TL866 ll Plus and ordered a SOIC8 clamp. I want to flash the Bios on circuit.
    I don't know which of the two chips are the bios.

    Near the CMOS Battery: MXIC MX25L8006E
    Near the CPU: AH1721 259(8)128CSIG E7A026 the 9 can be a 8.

    Where can i find a clean bios file, for flashing with the adapter?

    Sry for my bad english and thanks for your help.

      The chip with 128 or 256 is the main bios . Not advisable to flash with a clamp. Instead order a socket and desolder the bios chip and put in socket and then proceed to flash. You can upload your existing bios in dedicated "BIOS SECTION" and ask for a clean me bios.

              Dell Latitude 5400 Chromebook UEFI bios
              by jhanra
              Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

              so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
              in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...

              by TripTop
              Hi

              i have dell latitude E7270 with following symptoms:
              - takes long time to restart.
              - sometimes powers on and then off
              - sometimes while working it just dies,

              From googling online bios clean could possible resolve this?

              i was able to save bios and was going to try bios clean myself but get an below error when i drop it in ME analyzer.(unsure whether this sometimes occurs or could be due to bad/corrupt bios)

              As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.
              I reinstall...

              Dell 9010 MT BIOS Update Always Fails
              by mikeybass
              Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...
