3Click OK. Windows shuts down your computer.
If for some reason you cannot use the Shut down option in Windows to shut down your computer, press the power button for about five seconds.
Warning
When you shut down your computer the power turns off, but some electrical current still flows through the computer. To avoid possible injury from electrical shock, unplug the power cable and modem cable from the wall outlets.
Protecting from power source problems
During a power surge, the voltage of electricity coming into your computer can increase to far above normal levels and cause data loss or system damage. Protect your computer and peripherals by connecting them to a surge suppressor, which will absorb voltage surges and prevent them from reaching your computer.
Warning
High voltages can enter your computer through the phone line connected to the modem. Protect your computer by plugging the telephone line into a surge suppressor with a modem connection. To further protect your computer during an electrical storm, unplug both the surge suppressor from the power outlet and the telephone line from the phone jack.
During a power failure, an uninterruptable power supply (UPS) supplies battery power to your computer. Although you cannot run your computer for an extended period of time with a UPS, a UPS lets you run your computer long enough to save your work and shut your computer down normally.
