Increasing Memory
Increasing memory capacity is an effective way to make programs
run faster. You can increase the amount of memory in your com-
puter by installing a dual inline memory module (DIMM), available as
an option.
Different capacities of DIMM are available. You can install DIMMs
directly in the memory slots on the bottom of the computer. Your
computer memory capacity can be expanded up to 256 MB (two 128
MB DIMM options).
Note: Base memory (32 MB or 64 MB) occupies one DIMM slot.
Attention: The ThinkPad 390X computer supports the PC-100 static
dynamic random access memory (SDRAM) card only. It does not
support the enhanced data output dynamic random access memory
(EDO DRAM) card. If you install a DIMM that is not supported by
your computer, an error code might appear when the system starts.
The appropriate memory option can be purchased through your IBM
reseller or IBM marketing representative.
To install the DIMM, do the following:
1. Power off the computer; then disconnect the AC Adapter and all
cables from the computer.
2. Close the LCD, turn the computer over, and then remove the
battery pack.
3. Loosen the screw on the memory slot cover; then remove the
cover.
