Computer will not start. • The battery may be defective or discharged to a critically low level.
Connect an external power supply (such as the AC adapter) or
install a charged battery. See “Using the battery” on page 48.
• Internal components may be above or below the acceptable operating
range (below -20° C or above 60° C). After the temperature returns to
safe operating range the computer will start.
The computer will not resume
operation after being suspended.
• The battery may be defective or discharged to a critically low level.
When the battery reaches a critically low level, the computer is forced
into Sleep mode to avoid a total system power failure. Connect an
external power supply (such as the AC adapter) or install a charged
battery. See “Using the battery” on page 48.
• The computer may be at the critical thermal limit. To avoid damage to
heat-sensitive components, the computer enters Sleep mode when the
computer operates above 60° C. Operation automatically resumes
when the computer cools to below 60° C. Move the computer to a cooler
location.

operation. Contact your local help desk.
The Status LED is red, blinking. The computer is powered on, running under battery power, and the
