Notebook does not turn on

■Connect the notebook to an electrical outlet using the AC adapter. Make sure all connections are secure and that the electrical outlet is providing adequate power. (If the notebook fails to turn on and contains a battery pack, the battery pack may be defective. Remove the battery pack from the notebook.)

■If the notebook is extremely warm, cold, or moist, return it to an environment within the specifications provided in your model-specific documentation. When you return to your work, be sure the vents are unobstructed.

■If you have just added a new memory module, remove the module. It may be incompatible with your notebook. Review the memory module specifications in your model-specific documentation.

Notebook turns off unexpectedly

■If the notebook turns off immediately after being turned on, the battery pack charge may be extremely low. Connect the notebook to external power, then recharge or replace the battery pack.

■If the notebook turns off while unattended, the system may have initiated Hibernation. To resume from Hibernation, press the power button (or slide the power switch).

■If the notebook turns off or initiates Standby and feels extremely warm, it may have exceeded the maximum operating temperature. Allow the notebook to cool down. Then, whenever you use the notebook, make sure that all vents are clear of obstructions.
