Embedded controller firmware tagged A505 EC for a Toshiba notebook, 1 MB in size, with no board number or version in the name. The EC governs power-on, charging, fan and keyboard behaviour, so a corrupt image can cause no power, no charge or random shutdowns. It goes to the chip holding the EC code, separate from the 4 MB BIOS dump of the same model. Read the existing contents before flashing and verify that the target chip is 1 MB and that the board matches.
