Lenovo ThinkPad T60p - Manual (Page 28)

Problem: The computer does not return from standby mode, or the standby
indicator stays on and the computer does not work.
Solution: If the system does not return from standby mode, it may have
entered standby or hibernation mode automatically because the
battery is depleted. Check the standby indicator.
v If the standby indicator is on, your computer is in standby mode.
Connect the ac adapter to the computer; then press Fn.
v If the standby indicator is off, your computer is in hibernation
mode or power-off state. Connect the ac adapter to the computer;
then press power button to resume operation.
If the system still does not return from standby mode, your system
may stop responding and you cannot turn off the computer. Reset
the computer. Unsaved data may be lost. To reset the computer,
press and hold the power button for 4 seconds or more. If the
computer is not reset, remove the ac adapter and the battery.
Problem: When you take action to return from standby mode, the computer
display remains blank.
Solution: Check whether an external monitor was disconnected or turned off
while the computer was in standby mode. If you disconnected or
turned off the external monitor, connect it or turn it on before
resuming the computer from the standby mode. When resuming the
computer from the standby mode without attaching the external
monitor or turning it on, and the computer display remains blank,
press Fn+F7 to bring up the computer display.
Note: If you use the Fn+F7 key combination to apply a presentation
scheme, press Fn+F7 at least three times in three seconds, and the
image is displayed on the computer screen.
Problem: The computer enters standby mode unexpectedly.
Solution: If the processor overheats, the computer automatically enters
standby mode to allow the computer to cool and to protect the
processor and other internal components. Also, check the settings
for standby mode, using Power Manager.
