Important tips
Be sure to follow the important tips given here to continue to get the most use and enjoyment out of your computer.
Failure to do so might lead to discomfort or injury, or cause your computer to fail.
Protect yourself from the heat that your computer generates.
When your computer is turned on or the battery is charging, the base, the palm rest, and some other parts
may become hot. The temperature they reach depends on the amount of system activity and the level of
charge in the battery.
Extended contact with your body, even through clothing, could cause discomfort or even a skin burn.
- Avoid keeping your hands, your lap, or any other part of your body in contact with a hot section of
the computer for any extended time.
- Periodically take breaks from using the keyboard by lifting your hands from the palm rest.
Protect yourself from the heat generated by the AC adapter.
When the AC adapter is connected to an electrical outlet and your computer, it generates heat.
Extended contact with your body, even through clothing, may cause a skin burn.
- Do not place the AC adapter in contact with any part of your body while it is in use.
- Never use it to warm your body.
Prevent your computer from getting wet.
To avoid spills and the danger of electrical shock, keep liquids away from your computer.
Protect the cables from being damaged.
Applying strong force to cables may damage or break them.
Route communication lines, or the cables of an AC adapter, a mouse, a keyboard, a printer, or any other
electronic device, so that they cannot be walked on, tripped over, pinched by your computer or other
objects, or in any way subjected to treatment that could interfere with the operation of your computer.
Protect your computer and data.
Before moving your computer, do one of the following, and make sure that the power-status indicator is off
or is blinking slowly:
- Turn it off.
- Put it in sleep mode.
- Put it in hibernation mode.
This will help to prevent damage to the computer, and possible loss of data.
Handle your computer carefully.
- Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects on your computer, display, or
external devices.
- Use a quality carrying case that provides adequate cushioning and protection.
- Do not pack your computer in a tightly packed suitcase or bag.
- Before putting your computer in a carrying case, make sure that it is off, in sleep mode, or in hibernation mode.
