Upgrading Memory

You can increase RAM (random access memory) with an optional memory expansion board or PC Cards.

To view the amount of RAM in the system:

■Windows Me and Windows 98—Select Start > Settings > Control Panel > Compaq Diagnostics.

■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 2000 and you experience problems with Hibernation after increasing RAM, verify that your hard drive has enough free space for the larger hibernation file.

■To view the amount of space required by the hibernation file:

❏Windows Me and Windows 98—Select Start > Settings > Control Panel > Power > Hibernation tab.

❏In Windows 2000—Select Start > Settings > Control Panel > Compaq Power > Hibernation tab.

■To view the amount of free space on your hard drive, select My Computer. Right-click your hard drive, select Properties.
