Heat Problems Keep in mind that your notebook normally gets warm during routine operation. Charging the battery and running games and other programs that drive CPU usage toward 100% can further increase the notebook's temperature. If the notebook gets unusually warm • Provide adequate ventilation around the notebook. Make sure there is adequate clearance at the back of the notebook, so that its fan vent is not blocked. • Always set the notebook on a flat surface, so that air can flow freely around and underneath it. Do not place an operating notebook on carpeting, clothing, or other soft surface, as this can block the fan's air intake on the bottom of the notebook. • Always turn off the notebook or put it into hibernation before placing it in a carrying case or other enclosed space. • Make sure the fan is working properly. If needed, test the fan's operation with the e-DiagTools diagnostics-see "Using the e-Diagtools Diagnostic Tests" on page 25. Keyboard, Touch Pad, and Mouse Problems If the touch pad is difficult to control • Customize the touch pad by modifying Mouse properties: click Start, Control Panel, Printers and Other Hardware, Mouse. If the pointing devices don't work • Don't use the touch pad while the notebook is starting up or resuming from standby or hibernation. If this happens, try the following: • Press any key on the keyboard. • Put the notebook on standby, then resume operation. • Restart the notebook: click Start, Turn Off Computer, Restart. • Test the keyboard and pointing devices with the e-DiagTools diagnostics-see "Using the e-Diagtools Diagnostic Tests" on page 25. If the embedded numeric keypad doesn't work • To type numbers, make sure Num Lock is on. • Make sure the embedded Keypad Lock (Fn+F8) is on-or that you press and hold the Fn key to temporarily access the embedded keypad.

Heat Problems
Keep in mind that your notebook normally gets warm during routine operation. Charging the battery
and running games and other programs that drive CPU usage toward 100% can further increase the
notebook’s temperature.
If the notebook gets unusually warm
•
Provide adequate ventilation around the notebook. Make sure there is adequate clearance at the
back of the notebook, so that its fan vent is not blocked.
•
Always set the notebook on a flat surface, so that air can flow freely around and underneath it. Do
not place an operating notebook on carpeting, clothing, or other soft surface, as this can block the
fan’s air intake on the bottom of the notebook.
•
Always turn off the notebook or put it into hibernation before placing it in a carrying case or other
enclosed space.
•
Make sure the fan is working properly. If needed, test the fan’s operation with the e-DiagTools
diagnostics—see “Using the e-Diagtools Diagnostic Tests” on page 25.
