The W5G00F has everything necessary for normal mobile work in terms of connectors and interfaces. The left side of the computer offers the following (from left to right):

• Modem port (RJ-11)
• LAN port (RJ-45)
• 4-pin FireWire port (it is marked as DV, meaning Digital Video, and is meant for connecting high-end digital video equipment)
• USB 2.0 port
• Card-reader (Memory Stick/ Memory Stick Select/Memory Stick Duo/Memory Stick Pro/Memory Stick Pro Duo/Multi Media Card/Secure Digital)

• Optical drive with an activity indicator, eject button and an emergency eject hole

On the right panel the notebook has the following (from right to left):

• Universal ExpressCard slot with an eject button

• Volume control
• Microphone input
• S/PDIF output (combined with a headphones output)
• USB 2.0 port
• D-Sub connector for an external monitor

The back panel of the W5G00F offers:

• Power connector
• TV-Out port (S-Video)
• USB 2.0 port
• Kensington lock

It’s indeed good to have USB ports on all the sides of the notebook because you can connect USB-interfaced devices where it is convenient.

On the bottom panel there are CPU, memory and hard drive compartments; a battery module with two locks; a Reset hole (in case the Ctrl+Alt+Del combination doesn’t work); stickers with information about the notebook model and the OS serial number.

There’s only one slot in the memory compartment. It is occupied by a 512MB module. The second slot is on the mainboard and is occupied with a 512MB module, too. The maximum amount of system memory the notebook supports is 1536MB. So, you can replace the accessible module with a 1GB one and that would be the best you could do to upgrade the notebook’s memory subsystem.
