Hello defcon5,
Welcome to the DigiKey TechForum! I was unable to find anything with eHFFE markings that would allude to a specific part or series. In researching the surounding components on the board, however, it appears to likely be a voltage regulator. To determine the manufacturer and part number of the IC, you will want to consult the laptop manufacturer’s documentation or inquire with them directly.
Regards,
Klint
