Stuff happens - and so it did for the ole Nokia 3110 Classic, it played submarine for 5 minutes in a washing tub filled with hot water and washing powder. Surprisingly it made a call to a friend while in the water. Unfortunately it didn't survive the ordeal and was dead after. It did it's job as a GPRS/EDGE modem for the DELL D610 laptop for more than a year. So a good time to take the Nokia 3110 Classic apart and have a look what's inside.

Removing the cover from a Nokia 3110 classicRemoving the Nokia 3110 cover

The first trick is to get the cover removed. No tools required, start in the middle and push a nail under the plastic edge. With a little pressure on all sides, the edge comes off without breaking it.

The PCB of the Nokia 3110 classic is a complex piece of electronics. Little to repair here, when broken.

Same view, now with the metal shields removed - they come off lifting the small clips of each hatch.

Even after all parts where cleaned from washing powder, the Nokia 3110 Classic didn't come to live.
Most likely the hot washing powder solution changed the resistance of the SMD resistors / capacitors.
