Hello and welcome to my first post! Hello Geekhack community!
So, My 1995 Lexmark Model M keyboard has been an excellent daily driver for me for my last year of High School and leading up to my first year in college. Unfortunately, my little cousin (4 years old) accidentally spilled soda on the keyboard and seemingly caused little damage other than a few sticky key caps (which were immediately cleaned). After awhile however, several keys have just stopped working; after dis-assembly, it was revealed to me that some of the soda had drained into the keyboard through the small gaps from the plastic that the metal bar sits in that supports the space bar. I tried squirting warm water into the key stems and tried to clean out the sticky sugar left by the soda that might be preventing the springs from properly contacting the membrane. After two attempts with squirting hot water into the keyboard to remove the sugar, dry, and then test again, nothing has changed; the broken keys are still broken and working ones still work. I really do not want to attempt to remove all of the rivets from the back of my keyboard (all of the rivets are still attached perfectly) and ruin what once was a perfectly good keyboard. Then again, I might just be trying to fix an issue that does not exist and something else might be wrong. So please Greekhack community, help me out; as a poor college student I would really love to use this keyboard in my studies (i do have a Focus 2000, but seriously, there is no comparison in my opinion; the Model M trumps it) and not have to break the bank to fix it or buy a new one. I will post a picture of which keys are registering, and hopefully we can go from there.
THANKS FOR READING!
TLDR: Keys on Model M wont work because little cousin spilled soda on it, tried to clean out membrane by using warm water, broken keys still broken, i dunno what to do, don't want to open it up, HALP.
