The first to open the display and the first host are different: when the display is opened will produce a current, if you open the display in the open after the host, then you turn on the monitor when the current will likely to impact the operation of the host and data destruction (although this is rare but carefully a little absolute benefit), it must first open the display after opening the host!!! PS computer booksToday's desktops are replaced with LCD screens. Will the voltage reduction of LCD be so great? The resistance is better than the ordinary screen, so the professionals will explain itOn the contrary, will the startup of the computer affect the LCD monitors that are better?
Never seen, because after opening displays cause hardware damage, the theory of things sometimes in fact does not exist, the regular computer power is with voltage regulator function, otherwise the power grid fluctuation can not play dead computer.For these, the regular manufacturers is considered in the production of graphics and other parts, even the CRT display, the boot is on the effect of instantaneous voltage fluctuation of power supply, this host made what effect (except for short), and liquid crystal display CRT relatively lower power consumption, so the impact is smaller. If the host starts to cause damage to the LCD, what about the monitor?
According to the traditional version, you turn on the monitor first, then the host, first off the main and then turn off the monitor. But this is more than 10 years ago.Now, it doesn't matter..
There is no difference between opening the monitor first and opening the host firstPay attention when you power offDo not force shutdownOne click starts off the computerForced shutdown is prone to bad systems and hard drives
1, the book is right2, the liquid crystal also has a larger start-up current, mainly because the backlight tube to start a larger current. In fact, almost all appliances start the current greater than normal work, including the electric light bulb3, after the start of the equipment must be a certain degree of influence will start the equipment, so the textbook is mainly required because the host is usually more expensive (especially before 90s), also host the stored data is often priceless. There is also the case that early computers failed to function properly when they detected that the peripherals were not working properly.4, modern computer protection measures are already adequate and need not be as strict as books. It is better to worry about the effects of water and dust on computers than on books
Computer class teacher, the first class will be repeated warning students: when the boot, first open the monitor after the host; when the power off, first after the main display!This opening and closing order is especially important for older displays, but it's not very important for monitors that have been produced in recent years, but in most cases the order is good or harmless.The first display is because when you press the power switch on the chassis, the screen displays some hardware and system related information immediately, as well as self checking information. If you turn on the host first and then turn on the monitor, then some of the information in front may be skipped and you can't see it. So, in order to see all the boot information, first open the monitor, then open the host power.Which information we usually do not care too much, so the boot is in the end which first opened, it will be nothing. Only when the system or hardware issues, and need to find some relevant reasons, then the boot self-test information is very important. So usually do not pay too much attention to boot, which first open?.
