Small 45.6 KB RAR package tagged 08111F01 and IT8987E, which names an ITE embedded controller chip. Its size fits EC firmware for that controller, but the name does not confirm which notebook it came from. EC code handles power sequencing, battery charging, the keyboard and fans, so a corrupted EC is a common cause of no-power or no-charge faults. Reflash it only after reading out the existing contents, and only on a board that carries an IT8987E. Check the board identification against the 08111F01 code if possible.
