1. If the total memory size is not the same as the value you calcu-
lated, power off the computer and see pages 54 and 52 to
reinstall the DIMM.
2. If you changed the memory installed in the computer, Sleep
Manager automatically updates the hibernation file (see “Sleep
Manager” on page 31).
How to Calculate Total Memory Size
Calculate your total memory size in kilobytes (KB) by adding the
DIMM memory size to the base memory size (32384 KB for a com-
puter with 32 MB base memory).
Note: 384 KB is reserved by the system.
For example, if you installed a 32MB DIMM to a computer with 32
MB base memory, you should have about 64 MB.
Your computer displays the memory size in kilobytes. For example,
640 KB (system memory) + 64512 (extended memory) = 65152 KB.
