About this board
This thread is for the Lenovo IdeaPad Flex 3 11IGL05 14IGL05 BM5899 CB.
Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash.
Files usually needed for this board
- BIOS (full SPI chip dump, .bin)
- EC / KBC firmware, if the board uses a separate EC chip
- 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.
