SO-DIMM memory (see “Memory Module Removal” in Chapter 3, “Disassembly and
Reassembly”).

External Diskette Drive Problems
Check the following problems to see the possible cause and solution.

Check that the system unit power lamp is on and the power-on screen appears on the LCD
panel.

documentation.
