You frequently operate your Windows 2000 Professional portable computer on battery power when you are traveling. When you use battery power, your Windows 2000 Professional computer is configured to enter standby mode after 15 minutes of inactivity.
Which components are turned off in this mode? (Choose two.)
- The CPU
- The monitor
- The keyboard
- The hard disk
B. The monitor
D. The hard disk
In standby mode, your Windows 2000 Professional portable computer will turn off the hard disk and the monitor. The CPU will reduce its power consumption in standby mode, but the CPU will not be turned off. Neither does the computer turn off the keyboard in standby mode. You can wake up a computer from standby mode by pressing a key on the keyboard, pressing a mouse button or moving the mouse. Standby mode is useful for saving battery power on a portable computer.
The hibernate mode offers further savings in battery power. In hibernate mode, the contents of RAM are written to a hard disk, and the computer powers down. In hibernate mode, a computer’s CPU, hard disk, keyboard and monitor are turned off. You can wake up a computer from hibernate mode by pressing the power button, which powers up the computer and transfers the saved contents of memory from the hard disk back to RAM. You can configure power settings on your Windows 2000 Professional computer by using the Power Options Properties dialogue box. You can view the Power Options Properties dialogue box by double-clicking the Power Options icon in Control Panel.
