About this board
This thread is for the Lenovo 720S-14IKB ideapad with main board LA-E581P.
Lenovo had this board built by Compal; Compal board numbers start with LA- and end in P. Check the number printed on the PCB before you download.
What this thread covers
- BIOS (full SPI chip dump, .bin)
- Schematic (PDF)
- Boardview (.brd / .bdv / .cad)
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 LA-E581P in File Finder.
