Upgrading Memory

Your computer comes with random access memory (RAM)
preinstalled in a memory expansion slot under the palm rest. You
can increase the RAM in your computer with optional memory
expansion boards or PC Cards. Memory expansion boards can be
installed in the memory expansion slots on the bottom of your
computer or under the palm rest.
To view the amount of RAM in the system:
Windows 98 and Windows Me—Select Start > Settings >
Control Panel > Compaq Diagnostics.
Windows NT 4.0 and Windows 2000—Select Start >
Programs > Administrative Tools > Compaq Diagnostics.
When RAM increases, the hard drive space reserved for the
hibernation file also increases. Windows 98 manages this
increase. If the computer is running Windows NT 4.0 or Windows
2000 and you experience problems with Hibernation after
increasing RAM, verify that your hard drive has enough free
space for the larger hibernation file.
