If your your shift keys stopped working do the following. buy a 49g+ (its worth it I promise). solder through the blue buttons under the battery cover on the old 49g. remove the case portions. remove the black spacer seperating the two portions. I additionally removed the entire heat sync but this may prove to cause issues later. I did not want it to short out anything after having removed the spacer. Now I have 2 calculators.
