What if the computer crashes? [Humorous joke]

Don't think this little question is funny. Sometimes when turning the notebook screen or leaving the computer for a long time, or accidentally pressing the notebook sleep button, the notebook sleep button is the power-on button. Press the computer and you will fall asleep. Many friends who don't know computers are often caught off guard and at a loss when they encounter such a situation. If the computer is asleep, you should press the power-on button. Be careful not to press it for too long. It must be closed after more than three seconds. You can also set the notebook to never sleep when the screen rotates or the cover is lifted.

Settings: Control Panel-All Control Panel Items-Power Options-Edit Plan Settings-Put the computer to sleep for "Never". Other models of notebooks are extrapolated. )

Sleep is set to never sleep or set the way you want.

Black screen caused by computer system being destroyed or poisoned.

If the computer system is damaged or poisoned, this is a good judgment. Restart the computer directly to enter bois interface or press F8 to see if you can enter safe mode. If the boot can exit the bois interface or enter the safe mode, it means that the hardware itself is not broken, just the operating system problem. This is much simpler, just reinstall the operating system.

Black screen caused by damaged notebook hardware

Generally, the most common and critical hardware that can lead to black screen are power supply, LCD, memory stick, hard disk, motherboard and so on. This requires us to rule it out one by one. Because the notebook is complicated to disassemble, it is generally difficult to do it by ourselves, but we can find out the reason first and then take it to repair, which can save a lot of money or make it easier to do it by ourselves.

First, check the power supply to see if the laptop battery is charged and the power plug is plugged in. It only depends on whether the power indicator is on or not. If there is no external power supply, plug it in first. Before Bian Xiao, a friend showed me a notebook with a black screen in a panic. Bian Xiao asked him: Has the notebook ever been dropped? Has the child ever sat on it and fucked around? (I have met a notebook LCD screen that was broken by a child.) My friend replied: No. Later, Bian Xiao directly plugged in the external power supply, and everything was fine! The notebook battery is dead, resulting in a black screen. So, first check whether there is a problem with the power supply. If there is something wrong with the notebook power supply itself, even if the external power supply is plugged in, the screen will be black, so we have to remove the power supply first and then plug it in. If the external power supply is plugged in and turned on, it means that the internal power supply of the notebook is broken. Just buy a new one for yourself!

If the power indicator is always on and the external power supply is plugged in, it means that the power supply is ok. At this time, carefully check whether there is wind at the cooling fan port of the notebook computer and whether the hard disk indicator light is on. If there is nothing wrong with the cooling fan and hard disk, restart the computer, carefully stick your ear to the notebook to hear if there is a "tick-tock" sound, or if there is a "tick-tock" sound all the time, it may be that the memory stick of the notebook is loose, so turn on the computer and plug it in again. Generally speaking, memory chips are not easy to break, and the chances of notebook memory chips loosening are not great.

The above steps have been ruled out, and it is necessary to detect the problem of graphics card or LCD. First of all, we need to prepare an external monitor, preferably a desktop monitor. Connect the external monitor to the external display interface of the notebook, which is the line that connects the desktop monitor to the host graphics card interface. If an external monitor is connected to the laptop, please start the laptop. If the external monitor shows that everything is normal, it means that the notebook motherboard, CPU, hard disk, graphics card and memory stick are all fine. This is the problem with the notebook LCD screen. There are several reasons why the notebook LCD screen is broken: first, there is something wrong with the LCD LED screen, and second, there is something wrong with the LCD screen connecting to the graphics card interface or line on the motherboard. If there is such a problem, I suggest that you don't have to do it yourself, just go to the after-sales or maintenance site for testing. If you can fix it, try to fix it. If it can't be repaired, replace it with a new monitor screen. If the external monitor can't display anything, it means that the motherboard or graphics card is broken. Generally speaking, the probability of hard disk failure is much smaller. Basically, it can be said that the graphics card is broken, the graphics card is burnt out or the line connecting the graphics card and the motherboard is broken, because now the notebook graphics card is soldered to the motherboard, and the broken graphics card means changing the motherboard. However, if it is only poor contact at the weld, it can be re-welded.

It may be because the temperature of the notebook is too high, and the notebook often plays games, so the heat dissipation performance of the notebook is not good, so there will be a situation in which the graphics card is directly black and white when the temperature is too high. At this time, turn it off quickly and take it to test to see if the graphics card is burnt out. If the graphics card hasn't burned out, you just need to "wash and bathe" the notebook, that is, thoroughly remove dust, clean the exhaust system again, coat it with silica gel and replace it with an electric fan.

In short, don't panic when you encounter a black screen in your notebook. We must check what is wrong first. Know where the problem lies, prescribe the right medicine, find a solution, and implement it one by one! Don't disassemble the machine yourself as soon as you encounter such a problem, it is a loss, and you can't cause a bigger problem because of a small problem!
