Got a dv4-1645dx. The HDD led comes on amber/red occasionally while sitting on desk, being used. I think this is the protectsmart kicking in as everything stops. What I need to know is where is the protectsmart? is it part of the os or a hardware item i can look at? The laptop is useless as is. The top cover metal over the usb ports has a crack in it which means it was dropped or 'bent' pretty bad. I have changed out the HDD with a compatible drive and I tried to disable the protectsmart. Says it is but??? Anyway, I've had it apart and put in copper shims for the heat. Problem still exists. Any help is appreciated.
BTW I tried searching for 'protectsmart dv4' and could only get one screen. After that it changed the search to 'photosmart dvd'. Tech company huh?
Thanks
Matt.
