If the black screen is caused by software, take the Windows system as an example, you can restart the machine, press the F8 key several times when booting up, and bring up the system's boot options menu. X0D X0a: After the system boot options menu comes out, select Enter Safe Mode. If you can enter the safe mode normally, you can delete the software or driver installed before the black screen in the safe mode.

x0d x0a1) is the cause of static electricity, sometimes static electricity will cause the circuit of the notebook motherboard to be abnormal, resulting in no reaction on the screen after the power is turned on. You can try to turn off the battery and power of the laptop, and then press the power start of the laptop several times to let the machine release the static electricity. Then connect the power supply, turn it on, and see if it can solve the fault.

x0d x0a2) memory is loose or the memory is faulty. There are several major components of a laptop computer, including the CPU, motherboard, memory, and graphics card. These parts are indispensable, as long as one of them has a problem, it will cause the laptop to not function properly, the most common is that the boot does not respond.

In general, the probability of CPU and motherboard failure is relatively small, and it is more common for the laptop to fail to boot due to loose memory. At this time, first remove the battery and power supply of the notebook, if it is not difficult to remove the computer, you can open the back cover of the notebook by yourself and reinsert the memory. After plugging in the memory, power it on again, start the machine, and see if you can solve the fault.

x0d x0a3) The LCD component of the notebook is faulty. There are some notebooks that are a little older, and this may be the case. Display components generally include displays, data cables, and some other small parts.

If you have a desktop monitor, try plugging it to the VGA display connector on your laptop, and then switch the display to the VGA external display on your laptop. If you can switch to an external monitor, it means that there is a big problem with the display part. x0d x0a4) graphics card hardware failure, the graphics card is responsible for the source of all the display output of the computer, so it has a problem, there is no display on the screen.

If the graphics card is broken, the average user can't solve it, and the only way to solve it is to find the computer's after-sales service. If the notebook is within the warranty period, it can be taken for free inspection and repair.

Not a memory issue.

Because, even if the memory is incompatible, you can turn on normally, but the incompatible memory is not displayed.

In your case, you must have slammed the hard drive or something. As a result, when you boot up, the hard drive does not respond, so it can't be turned on.

Solution: Replug the cable of the hard drive, don't unplug it, just plug it in.

You should check it,If you add a memory module has a problem,Unplug it should also be solved,Are you adding a memory module when the original memory module or something else touched,Causing loosening or something,Generally adding a memory module will not have such a problem,I often check and pull out the memory module,My home is also Dell's,Desktops and notebooks are not like this。

Two possibilities, one is memory incompatibility, conventional memory is generally now DDR3 or 4, the frequency should be the same as much as possible, the problem of the 20 motherboard itself causes the memory to be not expandable, you must go to the special point to expand,

It is recommended that you clean up the dust of the computer, re-insert and unplug each board, wipe the gold finger with an eraser, re-wipe the CPU with silicone grease, clean the dust on the radiator, and then install the machine and turn it on to see if it can be turned on.

Dell laptops, black screen on boot is not just because of memory.

In addition to the reasons for the memory module, there are the following reasons for the black screen of the notebook boot:

1. If there is a problem with the connection of the monitor, check whether the monitor is connected correctly and whether the switch is turned on.

2. If there is a problem with the computer, observe whether the computer has a boot sound and whether it starts normally.

3.Display failure, if you eliminate the above reasons, it is a display failure, and it is recommended to send it for repair.

The new memory module and motherboard are not compatible.
