Garmin Edge 800 - Replacement Power Button

thingiverse

My 8+ year old Garmin Edge 800 had still been working pretty well, battery life _just_ able to handle a 200km ride, but the rubber at the power button disintegrated earlier and was basically loose in the shell. This probably isn't a long term fix, and 8 years has been a good run, so I'll likely replace soon, but I threw this together to get me by while I decide what to buy. To disassemble the Edge 800, a Torx T4 is required. Remove the 6 screws from the back, and carefully remove the front plate. Note: the front plate contains the touch sensor, separate from the screen, and there is a connector on the bottom which will separate. Next, remove the 2 screws holding the screen to the PCB. You do not need to remove the screen, but the screws also hold the PCB to the shell. Now carefully remove the PCB - it is held in place to more electronics below with a connector like the touch screen. When re-assembling, the PCB will easily connect back to the shell. When putting the face plate back on, it should connect to the PCB without issue, but as the connector hangs lose, it may not go right in - you can tilt the front sideways and us a screw driver to ensure a good fit. When disassembled, clear away any remaining rubber near the button space, print this (2 minutes!), and place from the inside. Nub on the top, 'bar' at the bottom to prevent the button from falling out of the shell. Added some dabs of hot glue on the sides, and then _immediately_ smoothed out with a screw driver - you want it very flat due to limited clearance. The glue provides a bit of spring action, and should help keep water out - for a bit.
