Computer stops responding<br />
Print these instructions now and keep it with your computer for reference later.<br />
If your computer is completely unresponsive (you cannot use the UltraNav pointing device or the keyboard),<br />
do the following steps:<br />
1. Push and hold the power switch until the machine turns off. After the computer is turned off, restart by<br />
pressing the power switch. If the machine does not turn on, continue to step 2.<br />
Note: Do not remove the battery and ac power to reset the computer.<br />
2. While the machine is turned off, remove all power sources from the computer (battery and ac power).<br />
Hold down the power button for 10 seconds. Plug in the ac power while keeping the battery out of the<br />
computer. If the computer does not turn back on, continue to step 3.<br />
Note: Once the computer starts up and enters Windows, use the proper shutdown procedure to turn<br />
the computer off. Once the machine is off, reattach the battery and restart the computer. If the<br />
computer does not start with the battery reattached, remove the battery and again start with step 2. If<br />
the computer starts with ac power but does not start when the battery is attached, call the Customer<br />
Support Center for support.<br />
3. While the machine is off, remove all sources of power from the machine (battery and ac power). Remove<br />
all external devices that are attached to your computer (keyboard, mouse, printer, scanner, etc.). Repeat<br />
step 2. If step 2 is unsuccessful, continue to step 4.<br />
Note: The following steps involve removing static sensitive components from your computer. Please<br />
make sure that you are properly grounded and remove all sources of power attached to the computer.<br />
If you are uncomfortable or unsure about removing components please call the Customer Support<br />
Center for assistance.<br />
4. While the computer is off, remove all sources of power and external hardware. Refer to the procedure in<br />
“Replacing memory” on page 143 on how to remove and reseat the memory modules. Remove any<br />
non-original memory module added to your computer. After removing the extra memory module and<br />
reseating the original memory module, repeat step 2. If the computer still does not turn on, consult the<br />
user's reference guide for other customer-replaceable components that are attached to your computer.<br />
If the computer still does not start up, call the Customer Support Center and a Customer Support Specialist<br />
will assist you.<br />
Spills on the keyboard<br />
With a mobile computer, there are increased chances of spilling liquids on the keyboard. Because most<br />
liquids conduct electricity, liquid spilled on the keyboard could create numerous short circuits, potentially<br />
causing irreparable damage to your computer.<br />
If you spill something on your computer:<br />
Attention: Be sure that no liquid creates a short circuit between you and the ac power adapter (if in use).<br />
Although you might lose some data or work by turning off the computer immediately, leaving the computer<br />
on might make your computer unusable.<br />
1. Carefully unplug the ac power adapter immediately.<br />
2. Turn off the computer immediately. If the computer does not turn off, remove the battery. The more<br />
quickly you stop the current from passing through the computer the more likely you will reduce damage<br />
from short circuits.<br />
3. Wait until you are certain that all the liquid is dry before turning on your computer.<br />
Note: If you want to replace your keyboard, you can purchase a new one.<br />
