About this board
This thread is for the 330S-15ARR Laptop (ideapad) 330S ARR V06.
Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash.
Files listed for this board
- 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.
