My late 2008 MBA that I purchased off of ebay has some issues with the trackpad. A very weird issue. With my computer flat down on a table or on the floor, the trackpad is very UNRESPONSIVE. (it responds to my touch at about 20%) When i put my hand/finger under the computer and raise it off of the flat surface, It works perfectly. If i try to use an object like the Tv remote, a drink coaster or anything small to give it some leverage off of the table, same thing happens (the trackpad is unresponsive) I erased the disk and did a fresh install of OS X today. Does anyone else find it strange that my hand is the only thing i can put under the macbook for the trackpad to be responsive? Anyone else ever had this issue?
