Do not perform a cold boot unless your keyboard and touchpad have no effect and you cannot perform a warm boot.
When you perform a cold boot, you lose data unless it was saved to a storage medium.
You can also perform a soft boot by saving your files and pressing <Ctrl+Alt+Del>. In ACPI, you can perform a cold(or hard) boot by pressing the power button to turn the computer off, waiting five second, and then pressing the power button to turn the computer on.
Tips for Using Your Computer
The following information helps you avoid potential problems as you use your computer:
Do not try to disassemble your computer. Opening the system chassis voids your warranty. Only an authorised manufacturer service center can replace or add any parts inside the chassis.
•Follow all the instructions and cautions in your computer user documentation.
•The LCD has a polarized surface and can be damaged easily. To prevent damage, avoid touching the screen.
•Use only approved AC adapters, auto adapters, memory modules and other options.
•Because a notebook computer is small and has restricted air flow around components, it is more likely to overheat than a desktop computer. A fan inside your computer runs when needed to help eliminate some heat. Make sure the fan vent on the right side of your computer is not blocked when you use the computer. (See Figure 1 on page 3 and Figure 2 on page 4 for the location of the vent.) Occasionally check the vents and remove any accumulated dust on the outside.
•Avoid using or storing the computer in extremely hot or cold areas, such as a car on a hot day. Keep the computer away from heaters and out of direct sunlight. Exposure to excessive heat may damage computer components.
