EC firmware archive for the HP ZBook 15 G3, Compal board LA-C381P, supplied as RAR. The embedded controller manages power-on, charging, keyboard and fans, so a corrupted EC image can cause no-power or no-charge symptoms. Compal is the ODM behind the LA-xxxxP numbering. Extract the file and flash it to the EC flash chip with a suitable programmer, checking that the chip size matches. Save the original contents first and confirm the board number on the PCB before writing anything.
