Tim -- Opening your PowerBook 100 ========================== WARNING: The PowerBook 100 is extremely fragile internally, and must be treated with extreme care to avoid an expensive repair bill. If you're not sure what you're doing, don't do it! If you break it, it's your responsibility! You MUST back up the RAM disk as this will be lost. You are strongly recommended to back up the hard disk as well. Memory and disk drives are very fragile and must not be removed from their anti-static packaging until you are grounded via an anti-static mat and wristband. DO NOT attempt to reinsert batteries until the machine is fully assembled and screwed together. You will need: - Static mat with wristband and earth connection - Clean tea-towel - Jeweller's flat bladed screwdriver, smallest available - 45 degree point Philips screwdriver - Small flat bladed screwdriver Notes on removing flat cables from sockets ------------------------------------------ The socket is in two parts which are pushed together to lock the cable in place. To remove the cable, use your fingernails to pull on the two lugs at either side of the socket (in the direction of the cable, not upwards) with equal force until it clicks out about 1-2mm.

Put aside. Turn PB over. Release latch and gently and slowly lift up the display. When it is clear of the body, lay it down screen up behind the machine being extremely careful not to stress the wires. If the display unit is to be disassembled, see below for details. Lay the tea towel over the display. Disengage the palm rest from the front of the case and the keyboard. Remove the palm rest and put it aside. Flip the keyboard over and lay it upside down on the tea towel. Be very careful not to stress the flat cables. Installing a New Memory Module ------------------------------ If there is a memory module already installed, it must be removed first. To remove the old module, it must be levered out very carefully using a wooden or plastic spatula placed between the memory module and the motherboard. Do n…
