With the increase of age, bags under the eyes become obvious, especially when you don't drink much water at night and sleep too late. I woke up the next day, afraid to look at my face.
The tea leaves left after drinking tea are also good for eyes, and the aroma of tea is also very good. You can also stick lemon slices on your eyes to eliminate bags under your eyes. Pay attention to rest at ordinary times, and generally you can use ice. If you can, you can insist on using appropriate eye cream and Yunrongji eye hazelnut essence cream every day. You can soak a little tea in hot water, let it cool, and apply cotton sheets to your eyes 15 minutes. Failure to lose weight or diet leads to malnutrition.

The display is "black screen" and the power indicator light is not on. Most of these failures are caused by the monitor itself. First, check whether the power cord of the monitor is connected properly, whether the power plug is in good contact with the 220V AC socket, and whether the power switch of the monitor is turned on. Confirm 220 volts AC.
Computer black screen?
After the electricity is correctly sent to the inside of the display, it can be judged that the display is faulty.
2. It is complicated to locate the "black screen" of the display, and the power indicator light is on. The failure may occur in the display, graphics card, motherboard or signal line. When testing, first adjust the brightness and contrast knobs to see if there is any change in the brightness of the screen, so as to eliminate the "black screen" phenomenon when the brightness and contrast are turned off. If the screen of the brightness and contrast knob is still a "black screen", check whether the signal line from the host to the display is plugged in, and whether there is any broken head or disconnection; After confirming that the signal line is intact, POST (power supply? Open? Self? Test power-on self-test). POST detection is a process in which the computer automatically starts to execute the POST diagnostic program after turning on the power switch every time to detect whether the computer system components are normal or not. When a problem is found in the detection, an error message or a series of beeps will be provided to the operator. In the failure of the "black screen" of the display, people can't see the screen information detected by POST, but they can judge the location of the failure through a series of beeps.
3. One long beep, two short beeps or three short beeps (which may be repeated) indicates that there is something wrong with the graphics card. Turn off the power of the host, open the chassis, and check whether the graphics card is in good contact with the expansion slot. If it is suspected that it is an expansion slot problem, it can be eliminated by plugging and replacing the expansion slot where the graphics card is located. If the fault is not eliminated, you can switch the graphics card to another matching microcomputer for inspection. If other microcomputers are also "black screens" after card replacement, it is judged that the fault is on the graphics card; If the graphics card works normally on other microcomputers, the fault lies in the motherboard.
4. Two short beeps. This failure may be in the motherboard and graphics card or the monitor itself (unlikely). Turn off the power, disconnect the monitor, remove the video card, and then restart the system. If the two short tones still exist, it means that the problem is the motherboard and the motherboard should be repaired. However, if the sound becomes long and short, it may be that the correct POST process noticed that the graphics card does not exist. Turn off the power and reinstall the graphics card, but don't pick up the monitor. Restart the system. If these two short buzzer signals still exist during POST, it is a graphics card fault; But if you only hear a short beep, the graphics card is good, and the monitor itself caused this error signal, so the monitor should be overhauled. During the period when the monitor is disconnected from the host and the host is turned on, it is necessary to ensure that the power supply is always available during the POST. During this period, the operation of drive A can be observed to judge its system function. After the POST process is completed, the A drive indicator will light up. When the drive stops, press DIR. Answer: Command the driver to rotate again, and the indicator light will light up again, indicating that the system function is normal and the host system board is intact. Through the above detection, the fault position of the "black screen" of the display can be determined.
