I recently received a Samsung laptop to restore to factory settings. Prior to doing this I backed up the owner's files, during which time I noticed that the laptop was intermittently failing to respond to touchpad clicks. (Both left and right.) I attached a mouse to the laptop and it exhibited the same symptoms. Also during a file download in IE, I left the mouse pointer over the pause button of the download progress bar at foot of the open webpage and without me clicking any buttons, the pause button alternated between pause and resume every few seconds. As if I was clicking the left button periodically. When this problem occurs, I can move the pointer with both the touchpad and mouse and the keyboard is also functional. Task manager shows no signs of excessive activity.
I have checked all the options in the control panel relating to the mouse and touchpad, disabling such things as tap and drag and reducing touchpad sensitivity. Nothing made any difference. I've checked in the BIOS to see if I can effect any changes there but other than disabling the touchpad completely there are no associated options. (The BIOS is up to date by the way.)
I have uninstalled and reinstalled all associated drivers and updated the touchpad driver from Samsung's website all without a positive result.
I proceeded with the system recovery after which the problem reoccurred. I have even tried a fresh install from my own retail Windows 7 DVD but the problem still occurs.
I am guessing that this has to be a hardware issue but I'm at a loss on how to address it.
The laptop is Samsung model RV510 running windows 7.
Any pointer would be very helpful. (No pun intended.)
