Hi , sorry i'm not short as the others, yesterday i updated the BIOS on Latitude 7480 since Dell said it was critical.
the laptop is now not being able to load at all - No Display
The ctrl+esc + AC does power for few seconds and then it shut down

i believe there is BIOS issue here - and wanted to know
1. if i can reflash it without soldering, for example with ch341 programmer clip ?
2. to get the correct bin file for flashing.
3. why everyone send Service tag - is that important? (my ST: 8DQ46H2)

1. Maybe.
2.Post your bios file here and we will help you.
3.That's the forum's rules and it makes it easier for us to find the bios.

W25P80 is not a bios chip. It only has one MB of data.

hi, thanks for taking your time to reply. i used your bios file and my laptop still wont boot up. its weird tho because..

1. the charger indicator lights up to white when i connect to charger

2. when i connect the charger, the keyboard lights go up for 15 seconds or so then it shuts down with no display and i cant press the power button again.

3. when i press CTRL - ESC while putting the charger, the keyboard lights stay on for at least 15 seconds and then it restarts again and again.

is this a bios problem? i changed to a working RAM and a working charger already so i dont think thats the problem.

NOTE: i used EZP2010 for programming the bios

I think this is a bios issue because your backup bin is not ok, when I compare from.a working bin
