Lenovo ideapad S110, BM5138 Main+ec

BIOS .rar 837 KB Shared

Main BIOS and EC firmware for the Lenovo IdeaPad S110 with board BM5138, packaged as an 837 KB rar. The main image goes to the system SPI flash, while the EC file is for the embedded controller that manages power, battery and keyboard functions. Reflashing both can fix dead boards or charging faults caused by corrupted firmware. No revision is stated, so compare your PCB revision with other sources, read and keep the original contents before programming, and confirm each image size fits its chip.
