Answer:
Standby and Hibernation modes are two different levels of PC power conservation. Standby mode powers down the most energy-hungry system elements after the system has been idle for a predetermined period of time. These elements include the monitor, hard drives, and CPU clock speed. Hibernation mode saves even more power by copying the system memory state to the hard drive and then turning off virtually the entire PC. Standby recovers in a matter of moments, but Hibernation saves much more power, which is why it is a popular mode in laptop/mobile PCs.
Power conservation modes are managed through the PC’s Power Options Properties dialog box. In Windows XP (Category View), click Start, Control Panel, Performance And Maintenance, Power Options, and then select timeout periods for the monitor, hard drives, and Standby mode. WinXP provides a series of typical preset schemes for different types of use, but you can also choose custom times. Remember to choose timeout periods that are longer than your usual pauses. For example, if you often go five to 10 minutes at a time without using the PC, set a timeout period of 15 to 20 minutes. Otherwise, the system will keep powering down and starting up again during average use. This won’t hurt the system, but it can be annoying. When you are finished making any changes, click Apply and click OK. |
