Performance problems

memory (RAM).
If the notebook stops responding
• Press CTRL+ALT+DEL, then use Task Manager to end the application that is
not responding.
• Press the power button for at least 4 seconds to turn off and reset the notebook.
Unsaved data will be lost. Then press the power button again to turn the
notebook back on.
• If nothing happens, insert the tip of a paper clip into the reset button on
the bottom of the notebook. Then press the power button to turn the notebook
back on.
• To avoid lockup problems, avoid turning the notebook off or putting it into
Standby while such applications are running.

Power and battery problems

If the notebook turns off immediately after it turns on
Battery power is probably extremely low. Plug in the AC adapter or insert a charged
battery.
If the notebook keeps beeping
The notebook beeps repeatedly or displays a warning when battery power is low.
Save your work, shut down Windows immediately, then insert a charged battery or
plug in the AC adapter.
If the battery does not charge
• Make sure the AC adapter is fully plugged into the power source and the
notebook, and that the light on the adapter is on.
• If you are using a power strip, remove the AC adapter from the power strip, then
plug it directly into a wall outlet.
• Make sure the battery is fully installed and locked in place.
