PowerBook G3 Pismo Processor Replacement

crwdns2915892:0crwdne2915892:0

This processor is not soldered to the logic board, and installing a replacement is very easy. There are processor upgrades that enable you to turn your Pismo into a G4.

    • Turn the keyboard locking screw so that it is parallel to the space bar.

    • Pull the keyboard release tabs toward you and lift up on the keyboard until it pops free.

    • Lift the keyboard out by pulling it up and away from you. Rest the keyboard, face down, on top of the track pad.

    • Pull the keyboard ribbon straight up from the logic board. Place the keyboard aside.

    • The connector may be tight. Gently rock the connector from side to side while pulling directly upward to free it. You can use this technique on many of the cards and cables you'll be disconnecting.

    • Make sure you have removed the laptop battery and CD/DVD modules from the expansion bays before proceeding.

  7. PowerBook G3 Pismo Processor Replacement, Airport Card: crwdns2935265:06crwdnd2935265:01crwdnd2935265:01crwdne2935265:0

    • Skip this step if your computer does not have an Airport card installed.

    • Firmly grasp the plastic tab attached to the Airport card and pull up and then to the right.

    • The Airport card is still attached to the antenna cable, so don't just yank it out of the slot.

    crwdns2913378:0crwdne2913378:0

    On mine, the airport card had been put it with the orange ribbon OVER the top, so had to unplug the righthand connector and then plug it back in after (see pic for Step 8)

    • Disconnect the antenna cable from the Airport card.

    crwdns2913378:0crwdne2913378:0

    To disconnect the cable, you just pull on it with enough force. It's just a straight up plug, no special tabs to unhook. I was a little shy as I never want to yank on old electronics, but just slowly turn up the amount of force you're pulling with until it comes loose.

    • Grasp the plastic tab on the processor's right side and pull it directly up.

    • Some processors may be missing the plastic pull tab. In this case, we suggest using a non-metal tool to gently pry up the processor. Slip the tool's thin edge under the front right corner of the processor and carefully pry it up.
