It8995e 128 Datasheet Online
The device functions as a central hub for managing low-level hardware tasks on a laptop motherboard: 128-pin LQFP (Low Profile Quad Flat Package).
When replacing this chip during repairs, it is vital to verify the specific part number (e.g., IT8995E-128 CXS ) to avoid compatibility issues. If the system fails to boot after installation, it likely requires manual firmware programming via the I2C or keyboard connector interface.
: Apply 3.3V to the motherboard's motherboard EC rail using a laboratory DC power supply, or plug in the original AC adapter.
