The correct computer switch machine sequence

A: Because the computer in the moment of power and power outage will have a large electrical shock, will send the host to the interference signal caused by the host can not start or abnormal, therefore, the power on the external device should be powered up before the host power. However, if an individual computer has an external device (especially a printer), the host does not work properly, in which case the reverse boot order should be used. When shutting down, instead, turn off the host and then power off the external device. This avoids large electrical shocks to the parts of the host. In the process of using the computer should also pay attention to the following points: and WINDOWS system can not switch, must be normal shutdown; If the crash, should first try to "soft start", and then "hard Start" (Press the RESET key), really no longer "hard shutdown" (according to the power switch number of seconds).

In the computer operation process, the machine of various equipment do not move casually, do not Plug and unplug all kinds of interface card, also do not load the external equipment and the signal cable between the host. If you need to make these changes, you must do so when the power cord is turned off and disconnected.

Do not switch the machine on and off frequently. Power-up immediately after shutdown will cause a sudden large inrush current, causing the device in the power supply device to be damaged, it may also cause a sudden acceleration of the hard drive, so that the disc is scratched by the head. Therefore, here we recommend that if you restart the machine, you should wait more than 10 seconds after shutting down the machine. In general, users do not open the machine without permission, if the machine abnormal situation, should be timely contact with the Professional maintenance department.
