Dear Lenovo users, hello!

1.If you have more than one antivirus installed on your computer, please keep only one test, as the antivirus software may have product conflicts.

2.Check whether the CPU usage is too high, if so, try to stop the process that is too high. If your computer is infected with a virus, it will also cause some processes to be overly occupied, so we recommend that you try to upgrade the virus database to the latest version and test the virus to rule out the virus problem.

3.Try adjusting the virtual memory.

4.It can be cleaned up by junk file cleaning tools carried by third-party software and other software, or it can be cleaned up by Windows built-in features, such as the "Disk Cleanup" function and the "Disk Defragmentation" function.

5.You can uninstall the software that is not commonly used on the system by adding a removal program.

6.Enter the msconfig command during operation to optimize the boot items and improve the system boot speed.

7.If your operating system has not been reinstalled for a long time, it is recommended that you also use the above methods to back up important data and reinstall the system for testing.

Other common causes:

1. If the memory is loose or there is a problem with the memory itself, try to reinsert the memory or change the memory;

2. The power supply chip of the motherboard is soldered or aged, the screen cable is loose or the motherboard short-circuits the power supply circuit of the screen;

3. The graphics card, south bridge, and north bridge BGA packaging chips are soldered or damaged.

If your computer is under warranty, please send it to the nearest Lenovo repair station for repair, after you say so, it may be caused by a problem with the solid state drive, or a mechanical hard disk

For the problem of laptop battery not charging, there are several reasons from the software side:

Drive; 2. Power management software.

Drive; In a notebook, the battery is controlled by a power management chip, and the corresponding power management driver needs to be installed in the system to make the device work properly. So when you find that the battery can't be charged, you're lucky.

Power management software.

Today's laptops also provide power management software for easy battery setup and management. And in this there is an important function. That is, the battery is in charging mode. There are two charging modes in Lenovo's power management.

Longest battery life and best battery life. The best battery life is designed to ensure the life of the battery. In order to avoid excessive charging and discharging of the battery. It will be on the battery level.

At about 60% of the time (note: depending on the model, this ratio is different), stop charging the battery, so that the number of charging times of the battery can be reduced, and the life of the battery will not be shortened because there is no power inside the battery.

And this is a lot in the fault of the battery not charging. So be sure to check this. Here are a few examples of how to illustrate:

Power management software.

Most. Good battery life: If you mainly use the power adapter and only use the battery occasionally, the battery will often be in a 100% state, but the life decay rate will be accelerated. Select this mode and the battery is rechargeable.

to 60%, thereby improving cell attenuation, prolonging battery life, and better protecting the battery. So set it to this mode. When the battery reaches about 60%, it will not be recharged.

Power management Qingtuan Liang.

If you set it to battery care mode here, it will stop charging when it is charged to about 60%, so be sure to check whether the charging mode of the battery is correct.

Be sure to select the correct battery usage mode, otherwise it will not be fully charged. How it works:

Click Start in the bottom left corner of your computer.

All programs. lenovo

energy

management

Power Options. Select the maximum battery life.

Note: Due to the fact that there are many versions or generations, the interface may change. Please refer to the actual interface.

Hardware problem: First, use the multimeter to check whether the power supply of the power socket is 220V, if the voltage is unstable, change the use environment, and then use the multimeter to see if the output voltage and current of the power adapter are consistent with the marked.

If it is not consistent, then there must be something wrong with the power adapter and needs to be replaced.

If normal. Then the problem is generally with the battery and the motherboard. This needs to be sent to the service station to find an engineer to solve.

1.Diagnose the fault first, the black screen can be many kinds. Generally, friends who don't know much about computers will only see it and say that the screen is black and they are anxious.

Don't panic,Let's first move the mouse or press the keyboard,See if the screen can be displayed,Then confirm that after the screen goes black,Whether the monitor and the host are still powered by the power light,The other is to turn on the stereo,Listen to whether the sound is still coming out normally。

2.If the screen goes black, the monitor is still lit up. Usually the normal display is a green light, and the no signal is an orange light.

If the display is a green light, then you can first consider restarting the computer, and then update the driver of the graphics card, and then enter the game test. If the orange light is displayed, then we need to check if the host is still working, if the host is working, it is a problem with the monitor. Check the signal cable of the monitor first to see if the contact is not good.

If it doesn't work, replace the monitor for testing, or find a computer company to help overhaul the monitor.

3.After the black screen, the computer console also stops working, and no lights are on (the host computer is powered off). This is to check the main chassis, after unpacking, first check whether the CPU fan is working normally, if the fan does not rotate or rotates very slowly, it is the fault of the CPU fan, causing the CPU temperature to be too high.

If the CPU fan is normal, then the next step is to check the power supply, first unplug the power cord and reconnect it once, see if the contact of the power cord is not good, the problem is still the same, you can consider replacing a power supply to test it.

4.There is also a situation where high-end graphics cards are generally independently powered, and if the power supply is not high, there will also be a black screen when playing games. In this case, the only way to do this is to replace a high-power power supply.

However, this kind of failure will not cause a black screen failure when you use a computer normally. The main thing is that when playing games, the graphics card is working at full load, and the power requirements for the power supply appear as soon as they are high.
