Key component upgrades
Your computer is designed to deliver solid performance. However, in
time, you might find that your applications demand even more
computing power. For this reason, you are able to upgrade key
components.
Note: Contact your authorized dealer if you decide to perform a
key component upgrade.
Memory upgrade
Memory is expandable to 2GB, employing 256/512 MB or 1 GB industry
standard soDIMMs (Small Outline Dual Inline Memory Modules). The
computer supports DDR (Double Data Rate) DRAM.
There are two memory slots on your computer, one of which is occu-
pied by standard memory. You can upgrade memory by installing a
memory module into the other available slot, or replacing the standard
memory with a higher-capacity memory module.

1 Turn off the computer, unplug the AC adapter (if connected) and
remove the battery pack. Then turn the computer over to access its
