How to find your serial number in software
You can find your Mac's serial number in Apple System Profiler: Select the Apple Menu > About This Mac, then (depending on the version of OSX you are running) click the System Report button or the More Info button. This brings up System Profiler, and on the Hardware Overview that is displayed by default you should see your serial number, and be able to copy/paste it. The procedure does vary slightly between different versions of OSX.
If you can't boot your Mac
If your Mac is not working, the serial number is printed on the computer casing but the location varies. Here are the main locations of serial numbers on Apple computers.
Unibody MacBook Pro - Laser etched onto the base.
MacBook, Early MacBook Pro, PowerBook G4 - Inside the main battery bay. Remove battery to locate.
iBook (White) - Under the keyboard. To lift keyboard, pull back on the release tabs between the F-keys.

iBook G3 Dual USB Upgrades
This page covers all the upgrades we sell for this range of Macs. Choose the type of upgrade you are looking for from the tabs below.
If you want specific upgrades for your exact model, choose it from the Model ID links below, or enter your serial number here:
In April 2003 Apple finally updated its consumer level portable range. Opting for a sleeker design like the PowerBook, Apple settled on an all new slim-line white perspex case (which was surprisingly rugged). They also upped the processor speed and introduced a new logic board.
All the machines shipped with FireWire and two USB ports (hence the name Dual USB). Also included was 10/100 ethernet and a socket for Apple's propriatory Airport wireless networking card. The first machines had a 12.1" screen, Apple later introduced a 14.1" version.
This was a long running series of machines, with many speed increases, taking this range from 500-900MHz on the G3 processor. The early models were shipped with Mac OS 9, once OSX was released later models shipped with this - all Dual USB iBooks can run OSX and OS9.
As with all of Apple's consumer level ("i" series) machines, they are not very upgradeable. Only the RAM and hard drive may be upgraded.
How to Identify these Machines
The G3 iBook Dual USB came in a number of different processor speeds, and in two sizes: a 12.1" and a 14.1" version. The 12.1" models have keyboards which run all the way across the case. The 14.1 units have a small gap between the edges of the keyboard and the sides of the laptop.
The units are very similar to the G4 Dual USB iBooks, and can only really be distinguished by using the Apple System profiler. This can be found on the Apple Menu in OS9, or from the About this Mac option in OS X. The first page in Apple system profiler will list the processor speed and type (G3 or G4).
If you are still unsure you can contact us on 01223 833 412 or by email for confirmation. If you want to upgrade but aren't happy to install your upgrades then we can help. Simply ask our engineers for further details.
Memory Upgrades
The iBook G3 Dual USB has 128MB soldered onto the logic board, and one RAM slot, which can take up to a 512MB stick. This gives a maximum of 640MB of RAM.
There are none available.
Difficulty 3 / 5 - Reasonably easy.
Turn off the machine and remove the power cable and battery.
The hard drive and RAM are housed below the keyboard. To remove the keyboard release the catches at the top of the keyboard (between ESC & F1 and F8 & F9). This reveals the internal parts.
There is metal protective plate secured with 2 screws. Remove the plate to reveal the RAM socket, which is easily reached and replaced.
Reassemble machine and the upgrade is done!
CD/DVD/Blu-ray Drive Upgrades
The iBook G3 Dual USB came equipped with either a CD-ROM, DVD-ROM or a Combo drive. This is via a tray loading mechanism on the right hand side of the laptop.
At present we don't stock internal CD or DVD writers for these machines. It is possible to use an external device via USB or FireWire (FireWire highly recommended).
