What is the situation when the Dell laptop suddenly has a black screen recently?

First, the driving problem.

Update the graphics card driver when the notebook has a blurred screen, black screen, freeze, white screen, or blue screen, if the problem disappears, it can be considered as a compatibility problem or the driver file is damaged or lost, which will cause the graphics card to crash, blur screen, black screen, white screen, blue screen, etc.

2. Third-Party Software.

After opening the overclocking software, if the video memory frequency exceeds the head, it is normal for the screen to have a texture error, blurred screen, black screen, blue screen, crash, and white screen, because the video memory works at an abnormal frequency, and higher frequencies will only make its work unstable, we just need to reduce or restore the default frequency.

3. Poor contact of LCD screen wiring.

This is the first step we take to check the hardware. The phenomenon of blurred screen and black screen appears irregularly, or the failure disappears after tapping and pressing the keyboard surface, which is often the result of poor contact between the LCD screen cable and the interface. We can eliminate the problem by simply plugging in the corresponding interface.

Fourth, oxidation reaction.

We first take out the LCD screen cable interface, wipe the gold finger at the connector with an eraser, and scrub the interface with cotton stained with a small amount of anhydrous industrial alcohol, in order to remove the poor contact caused by oxidation reaction or dirt.

5. Graphics card issues.

Since some laptop graphics cards use dynamic ** memory technology (i.e., DVMT, dynamic video memory technology), part of the memory capacity is used to allocate the graphics card. In the actual operation process, the internal structure of the graphics card may be damaged, resulting in a blurred screen, black screen, white screen, crash and other phenomena.

This phenomenon is a typical graphics card chip problem, the black screen is restored or similar to the graphics card has just been from the working state to the working state, first take a look at the temperature of the next temperature measurement software, and if the temperature is high, it will be disassembled and cleaned up, if the temperature is normal, this phenomenon is a problem with the graphics card chip.

First, remove the battery and power adapter, empty press the laptop power button for 5 seconds, and repeat three times. Release the charge of the shed on the motherboard, and then fork the memory cover. Plug and unplug the memory of the notebook, replace the memory slot, and then reboot the test.

If the fault persists, check whether the voltage from the power adapter is normal, and if it is normal, send it to the repair service station to test the motherboard.

The reasons for the sudden black screen of Dell laptop include: damaged monitor, damaged motherboard, damaged graphics card, poor contact of graphics card, damaged power supply, damaged CPU, high temperature of zero-shouting macro parts, artificially caused by black screen of the brain, etc.

A laptop is abbreviated as a notebook or laptop. Also known as "laptops, laptops, handhelds, or laptops", they are characterized by their small size. It is more portable than a desktop computer, and it is a small, portable personal computer. Usually weighs 1-3 kg.
