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.
