From Wee-Meng Lee:
Unresponsive keys can be caused by mild corrosion or dirt in the keys. I get it all the time. Being in Singapore it takes too much trouble to send a key to me from Club100 in the U.S. .
Try taking the key apart and cleaning the copper contacts first. If this repair works, you won't need to open up the M100 case or unsolder the keycap.
Steps:
- Pull out the key cap, by "levering" it out with two teaspoons.
- Use a jeweler's flat screw driver and pry open the latches at the sides to remove the top.
- Remove the inverted rubber cup.
- Check that there is still some black carbon attached to it; if not, you can try sticking some rolled up aluminum foil in it and in the mean time ask Rick for a key.
- Clean the copper contacts at the bottom of the key by using the eraser at the end of a pencil and rubbing gently until it's shiny.
- Put back the rubber cup, turn on the unit and press the cup down. With any luck, your key will work again.
- Reassemble the rest of the key.
