Answer to: How about the disassembly of the key board to change the battery?September 9 Original post by: Chris kupke , September 9 Text: The last couple that I have repaired have had weird keyboard faults and they both turned out to be poor seating in the edge connector under the keyboard. Pull off the four rubber feet and undo the screws. Take out the two visible ones underneath and the three under the silver tab directly beneath the touchpad. Unlock the ribbon edge connector and clean the ribbon contacts. It may be as simple as that. POSTED UNDER ANOTHER ISSUE.... HOPE THIS HELPS YOU..
