What Are the Best Tips for Buying a Desktop Computer?

Computer sleep (Sleep) is a new energy-saving mode when the computer changes from working state to waiting state. It is a newly added system function in Windows Vista and Windows7 operating systems. The way to turn it on is to click the drop-down arrow to the right of the power button in the computer system's start menu and select the "sleep" button. When the sleep state is turned on, all work of the system is saved in a system file under the hard disk, and at the same time, the power to all devices except the memory is turned off.

Computer sleep

Computer sleep mode combines all the advantages of standby and hibernation. After switching the system to sleep state, the system will transfer all the data in the memory to the hibernation file on the hard disk (this is similar to hibernation), and then turn off the power to all devices except the memory to keep the data in the memory (This is similar to standby). In this way, when we want to recover, if there is no abnormality in the power supply during sleep, we can directly from the memory

Put your computer manually

If you want to hang up, sleep can be powered off. So ... 1. In Vista, sleep and standby are integrated together, called sleep, also called

Press the power button to wake up, most home computers can also use the space bar or enter key to wake up; you can also set the sleep key to wake up.

Start computer sleep mode energy consumption halved scientific computers can save more than 20 billion kilowatt-hours per year

Computers have become indispensable office appliances in many homes and offices. However, paying little attention to computers can also cause a huge waste of power. Therefore, proper use and proper equipment are the key to computer energy saving.

The best way to reduce the energy consumption of your computer and monitor is to turn it off when not in use. If your computer has a "sleep" mode, make sure that it is enabled, and the computer enters a low-energy mode when not in use, which can reduce energy usage to less than half. You can also reduce the length of time before the monitor automatically enters Sleep mode. The computer also consumes 10 watts of energy in the "sleep" state; even if the computer is turned off, the computer still has 5 watts of energy as long as the plug is not pulled out. Therefore, please remember to unplug when not using the computer.

When computers need to upgrade equipment, consider these factors when purchasing: laptops use 90% less energy than desktop computers; inkjet printers use 90% less energy than laser printers; choose a copy machine that fits your needs and is the right size; printers Networking with copiers can reduce their idle time and be more efficient; choose a monitor of the appropriate size because the larger the monitor, the more energy it consumes. For example, a 17-inch display consumes 35% more energy than a 14-inch display.

Therefore, the scientific use of computers and its auxiliary equipment can save at least 0.3 kWh of electricity per day. There are about 350 million office and home computers in China. Based on an average of 200 days of use per year, using scientific methods can save more than 20 billion per year. Kilowatt hours is equivalent to reducing more than 20 million tons of greenhouse gases.
