Fixing the button bar connector
(see part 3 of the FAQ at http://www.geocities.com/SiliconValley/8130/faq.htm, UK faq site, local copy here
- 15.jpg ( 168 K) : Step one: battery
compartment removed. If you are doing the button bar surgery,
you should remove the backup battery, but you won't need to
remove the main batteries. If you leave the batteries
connected then during the surgery you may get strange bleeps
and screen patterns happening, so it is probably best to
disconnect them, unless your set-up takes a long time to restore.
- 16.jpg ( 168 K) : The battery connector
released from its retaining tab, but not disconnected
from the body.
- 17.jpg ( 176 K) : Rather uninteresting
view when
battery compartment removed.
- 01.jpg ( 200 K) : After removal of the
keyboard cover. (I did this by lifting out the front, next to the space bar, first, then
easing the back out.)
- 18.jpg ( 192 K) : Removing the keyboard
cover.
- 19.jpg ( 160 K) and
20.jpg ( 168 K) : The back of the keyboard cover is held down by a total of six tabs; the edge ones point backwards
and the centre ones hook downwards. This is why `considerable force'
is needed at this point.
- 02.jpg ( 256 K) : After removal
of the keys. When I removed the
battery compartment, my button bar bowed out under the strain of
the springs. I think it might have been a good idea to remove
the springs. WARNING:
When I proceeded with the surgery for the button bar, my
left hinge broke.
- 09.jpg ( 240 K) : WARNING: when lifting
up the keyboard cover, ONLY insert your tools in the
dead centre, where there is a dimple in the circuit board.
Preferably use a blunter plastic instrument. Notice I
used a metal screwdriver, and at the tricky moment when
lifting the keyboard cover's two prongs out, I scratched the circuit
board underneath. No real damage done, but if I had been clumsier,
it could have been terminal, I guess.
- 04.jpg ( 168 K) : WARNING: When I
lifted the main circuit board, my port protector popped out.
Maybe the FAQ could give advice on how to prevent it from so popping.
My guess is it might help to tape the protector back, but
I couldn't see how the spring fitted into things. I left this out
when I reassembled. Here is
a picture by mikehughes showing how the spring should be fitted
- The right angled end fits into the small hole and the tiny "lip" on the plastic part hooks over the pcb. It forms a kind of "runner" to keep it on.
- 03.jpg ( 200 K) : After lifting
the main circuit board. Note the blue connector strip which
is hanging loose. Note also the main top to bottom connectors
in white. The blue connector should go back in the centre
white connector at the bottom front.
- 05.jpg ( 184 K) : Another view of the blue
connector. Note the tabs on the white connector underneath,
which are sticking up. They compress back in, as you see later.
- 06.jpg ( 208 K) : another view
- 07.jpg ( 184 K) : Feeding the blue connector into its hole. This was tricky.
- 08.jpg ( 200 K) : This blue connector is
not home yet.
- 21.jpg ( 176 K) : I found it helped to
attach a piece of tape to the blue connector, to pull on it. I
pulled with my fingers and with a pair of plastic
tweezers at the same time. Notice I have pushed down the
two little white ears in the white connector.
