An inescapable truth in a technological world is that in order to keep up, one must trade up. Who, for example, would have imagined that the massively expansive 2GB hard drive in 1998’s PowerBook G3 would be considered inadequate for today’s modest library of MP3 files? Or that the original Titanium PowerBook G4’s 64MB of RAM would be incapable of booting the version of Mac OS current in the waning weeks of 2002?
There’s no need, however, to give up on your old PowerBook. The original PowerBook G3 Series (Wall Street) can still be a player—if it’s given enough RAM and a big enough hard drive. Likewise, you can coax a reasonably powerful growl from Jaguar on an original PowerBook G4.
In the following pages, we’ll show you how to replace the hard drive and upgrade the RAM in a Wall Street PowerBook G3 and a Titanium PowerBook G4. To complete the picture, look for our instructions for upgrading the two PowerBook models issued between them—the Lombard and Pismo PowerBook G3s—at
So slip on your grounding strap, unlatch the tool chest, and let’s begin.
What you’ll need
Small Phillips-head screwdriver
Torx T-8 screwdriver
Plastic shim (two old credit cards may do)
PowerBook G3 Series (Wall Street)
1. Prepare to upgrade the RAM
If you looked at specifications alone, you’d think this PowerBook’s maximum RAM capacity was 192MB. Small high-capacity RAM modules weren’t available when the Wall Street was released, but they are now. You can actually install as much as 512MB of RAM if you put 256MB 144-pin SDRAM modules in both the user-accessible upper RAM slot
the supposedly for-Apple-techs-only slot beneath the processor card.
First, shut down the PowerBook and remove all attached cables. Pull the front expansion-bay release handles toward you to eject any inserted peripheral modules (the battery and the CD-ROM drive, for example). Place your index fingers inside the expansion bays and locate the ridged, plastic tab on the roof of each expansion bay. Pull the tabs toward you to release the bottom of the keyboard.
Lift the bottom of the keyboard, and pull it toward you to release the metal tabs that hold the top of the keyboard in place. Fold the keyboard back toward you, making sure not to tug on the keyboard’s fragile—and breakable—connector ribbons.
2. Access the first RAM slot
Now that you’re inside the Mac, you can access the first RAM slot—but wait to put in the card if you’re going to upgrade the hidden RAM slot, too. Be sure to use a grounding strap if one came with the RAM you purchased. If you don’t have one, touch the metal hard-drive bracket to the side of the heat shield to discharge any static electricity.
Using a small Phillips-head screwdriver, unscrew the two screws that hold the heat shield in place
. Use needle-nose pliers to remove the screw closest to you if your fingers can’t grasp it. Pull the shield’s wire handle toward you to remove the shield.
The white slot on top of the processor card is the PowerBook’s user-serviceable RAM slot. If you want to upgrade the PowerBook via this slot only, insert a 144-pin SDRAM module (up to 256MB) at a 45-degree angle and press it into place so that the indentations on the side line up with the snaps on the retaining brackets
. (If your RAM upgrade is complete, skip to step 4.)
If you want to upgrade the Mac’s other RAM slot, refrain from installing RAM in the top socket for the time being. The hidden slot is on the underside of the processor card (the user-upgradable RAM slot sits atop the processor card).
To reach the hidden slot, first unscrew the single Phillips-head (shown here) or Torx T-8 screw at the bottom left corner of the hard-drive bracket
. Pull up on the left side of the hard-drive bracket and lift it and the hard drive out.
Use a plastic (not metal) shim (a couple of old credit cards you’re not attached to will do) to carefully pry up the right side of the processor card
. (Don’t use a screwdriver! It can damage the processor card’s delicate traces and destroy your PowerBook.) On the underside of the processor card, you’ll see another white RAM slot filled with the PowerBook’s original RAM. Remove this RAM by gently prying apart the retaining brackets until the module pops up. Replace it with a module no larger than 1.5 inches (the top slot can accommodate 1-, 1.5-, and 2-inch modules).
4. Put back the processor card
Replacing the processor card isn’t difficult, but you must put it firmly in place. Your PowerBook won’t boot up if it’s not completely mated with the motherboard.
Slip the two plastic tabs on the left side of the processor card into the slots on the left side of the processor bracket, and press the processor card firmly into place.
5. Prepare to upgrade the hard drive
All PowerBook G3 Series models use 2.5-inch IDE/ATA hard drives—either the Slim 12.5mm or SuperSlim 9.5mm varieties. In step 3 you learned how to remove the hard-drive bracket (and hard drive). To replace the drive, first remove the data connector.
Using a Torx T-8 screwdriver, unscrew the two screws that hold the green data connector to the hard-drive bracket
. Turn the bracket over so you can see the drive, and use a plastic shim (or a well-honed fingernail) to carefully separate the connector from the hard drive at the base of the connector. To avoid damaging the connection between the motherboard and the hard drive, don’t pull on the green circuit board! Turn the bracket over, and remove the four black Torx T-8 screws that hold the drive to the bracket.
6. Reassemble with the new hard drive
Unlike hard drives intended for desktop computers, drives intended for laptops are always sold configured with master jumper settings—so you needn’t worry about them.
Replace the drive, screw it into the bracket, attach the data connector, and press the new hard drive into place. Tighten the screw that holds the drive in position, and replace the heat shield. Put back the keyboard and expansion-bay modules. Plug in the power cord and any peripheral cables.
Finally, insert a system software CD. You’ll need to format the new hard drive, so push the power button and hold down the C key to boot from the CD. If you’ve booted from a Mac OS 9 CD, launch Drive Setup, which you can find in the Utilities folder inside the Applications (Mac OS 9) folder. Select the drive in the Drive Setup window, and click on the Initialize button.
If you’ve booted from a Mac OS X Installer disc, select Disk Utility from the Installer menu, select the drive in the left side of the Disk Utility window, and click on the Erase tab. Choose Mac OS X Extended from the Volume Format pop-up menu, and click on the Erase button. Install Mac OS and enjoy.
