Opening the 95LX Case

Opening the 95LX Case

  1. 1. Back up any file you don't want to lose.
  2. 2. Remove both the main and backup battery covers.
  3. 3. Remove the main batteries. I left the backup battery in and didn't loose and C drive files.
  4. 4. Remove the four rubber feet. Simply bite each one with a small alligator clip or a pair of needle-nose pliers and pull straight out.
  5. 5. Remove the four hex screws now revealed. Officially, they require a special tool, but a 0.050-inch Allen wrench or a Torx T-6 driver works fine.
  6. 6. Spread the case halves apart about 3/4 of an inch at the main battery edge. There is a keyboard connector running between the "MENU" and "=" keys that has two press-fit retainers at each end. Gently pry the case halves apart in that area. Using a flat-head screw driver will work, but prying the case open can mar the outer plastic, so be careful.
  7. 7. The LCD screen connects to the main PC board via a small flexible cable. The connector on the PC board has two small retaining clips at each end. To release the flexible cable, use a small screw driver or pin to slide the two retaining clips away from the backup battery.
The repair for Jeffrey's problem was easy. The wires going to the AC adapter socket were being crimped together by one of the socket mounting guides. It was a simple matter to reroute the wires. The problem David addressed (the speaker wires) was easily confirmed by splitting the case. Correcting the problem requires resoldering the break in the wires or replacing the wires -- a job for the tech guys at Corvallis.

 I opened my case and confirmed that the left-most of the four pins in the 95LX's serial port had been pushed in. All four pins are soldered to the PC board and extrude through a small piece of plastic. The fourth pin had been pushed back in through the plastic so that only the tip of the pin was showing. The fourth pin had also broken free of the solder, but was still making contact with the board. I very carefully used a small flat head screwdriver to push the pin back out (away from the board) until the end protruding out the serial port was the same length as the other three pins. Since the pin seemed to be making good contact with the board, I did not attempt re-soldering the pin. I re-assembled the 95LX and it worked fine. I left my backup battery in while I opened the case, and the files on my C Drive were intact when I reassembled my 95LX.
