The computer always automatically goes black screen standby, why does the laptop automatically go bl

You're on standby this time. When you press the keyboard and mouse. Whether it can start normally again. If you can, try changing the keyboard. It's possible that the sleep keys of the keyboard are a little sticky.

Hello, the main reasons why the black screen cannot be woken up after standby are as follows:

1. If there is no external power supply; It may be that the battery is out of power, just connect it to an external power supply.

2. If you can't wake up when connected to the external power supply; The battery can be removed. Then connect an external power supply to power it on.

3. It is possible that the machine has a hardware failure; There are mainly hardware reasons for this; motherboard and motherboard power failure; Or a faulty display. We basically don't judge the failure of this kind of hardware. It can be sent to a professional for overhaul.

Here's the difference between System Standby and System Hibernation.

1. System standby: temporarily stop operating the computer for a period of time, and the computer will enter a power-saving mode when there is no work to do, but it will immediately enter the working state when performing operations such as tapping the keyboard and moving the mouse.

When the system is in standby, the data that is currently running is stored in memory, and the machine only supplies power to the memory, while components such as hard disks, screens, and CPUs stop supplying power. Since the data is stored in fast memory, it is faster to enter the waiting state and wake up. However, this data is stored in memory, and if the power is cut off, the data will be lost.

2. System hibernation: Computer hibernation is when the computer is not operated for a long time, the computer stops working and turns off the power of most components, at this time, you need to press the wake up button to wake up the computer and enter the working state.

When the system is hibernating, the computer will save the data that is currently running in the hard disk, and the power supply of the whole machine will be completely stopped. Because data is stored on the hard drive, which is much slower than memory, it is relatively slow to go to sleep and wake up, and you can completely disconnect the power of your computer while you are sleeping.
