NEC Aspire S Manual page 39

While the system is powered up, data may be written to the S-RAM or flash memory at any time. Before pow-
ering down the system, verify that of the 4 LEDs in the lower left corner of the CPU, only LD2 is flashing. This
LED is the farthest right of the LEDs. It should be flashing 0.5 seconds on/off (a slow flash). If it's flashing fast
or if any other LEDS are flashing on the CPU, wait until they stop or else the system data may be corrupted.
Turning off the power when other LEDs are flashing may corrupt the flash or S-RAM data. If the flash memory
becomes corrupted, the system may not come up. If the S-RAM data is corrupted, the telephones may have
erratic operation.
When powering the system up or down, wait 10 seconds before pressing the button again. This allows the sys-
tem to complete the startup/shutdown process.
