9 ways to save electricity on your computer.

1.Shutdown. Remember, all hibernation modes are not really shut down. If you're away from the computer for a long time, oh for God's sake, turn off the electricity-eating machine.

2.Hard disk. The hard drive is also a power-hungry guy, and it is always running, of course, we can't reduce the power consumption by reducing the number of revolutions of the hard drive, but we can turn the system into sleep mode when we are not using the computer.

3.Charge. Chargers are always vampires of electric energy. If you don't need to charge your phone anymore, please unplug the charger from the socket and remember not to let this vampire have any chance, hehe, it is also necessary to be on the safe side.

4.Set up. Necessary power-saving settings. Remember that many mobile phones have a power-saving mode, computers are no exception, most of the system's control panel, there are some power-saving settings, if you are careful to find a lot!

5.Receptacle. If possible, replace it with an energy-efficient self-energy power outlet, which can reduce unnecessary power consumption when the computer is turned on or off.

6.Process. Kill unnecessary processes. Especially the boot software on the notebook, try to do as little as possible, such as Bluetooth, wifi, etc.

If you don't use the line network, turn it off. Checking your computer's progress from time to time can also play a role in checking for viruses.

7.Virtual systems. If you have to use a Mac, PC

For Windows and Linux, you can try installing 3 systems on a single computer, or emulating the system. This not only saves the power of 3 computers, but also saves a lot of money to buy a computer.

8.Turn down the brightness. It turns out that turning down the brightness of the display can help save power, and if you're really not used to it, you can set the screen off when no one is around, or automatically reduce the darkness.

9.Hardware upgrades. Older CRT displays obviously consume more power than LCDs, so if we have enough money, it's a good idea to upgrade the hardware.
