About this board
This thread is for the Dell XPS 15z L511z.
Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash.
What this thread covers
- BIOS (full SPI chip dump, .bin)
Typical reasons to reflash: no power or no display after a failed BIOS update, a BIOS/supervisor password lock, or a corrupted Intel ME region.
Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
If you have a working file for this board, please share it below. More files: search Dell XPS 15z L511z in File Finder.
