ATI Hotkey POLLER service is installed if you update to the latest ATI video card drivers. ATI Hotkey POLLER provides the ability to hot key your display settings for what ever reason you would need this feature. Disable the service if you do not use hot keys for ATI software. User comments: docsandman I have a Dell Inspiron 9100 with Win XP pro. the ATI Hotkey Poller causes system sluggishness when battery operated. Disabling this service put me back to normal batter operations.
