PowerBook G3 Pismo Processor Replacement

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 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.

Edit Step 12 Processor  ¶ 

  • 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.

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)
