Opening the 95LX Case
-
1. Back up any file you don't want to lose.
-
2. Remove both the main and backup battery covers.
-
3. Remove the main batteries. I left the backup battery in and didn't loose
and C drive files.
-
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. 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. 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. 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.
