Standby or hibernation problems

Problem: The computer returns from standby mode unexpectedly by
disconnecting a device from the USB connector or carring your computer with
a USB device (especially a USB mouse) connected.
Solution: Your computer is enabled to return from standby mode when
detecting any activity on a device attached to the USB connector. Make sure to
disconnect a device from the USB connector in advance or disable this
function to prevent this problem.
Problem: The computer enters standby mode automatically.
Solution: If the processor reaches a temperature that is too high, the computer
automatically enters standby mode to allow the computer to cool and to
protect the processor and other internal components.
Problem: The computer enters standby mode immediately after Power-On
Selftest (POST) (the standby indicator light turns on).
Solution: Make sure that:
v The battery is charged.
v The operating temperature is within the acceptable range. Refer to
"Specifications" in this Guide.
If these items are correct, have the computer serviced.
