Hello, HP China, it's a pleasure to serve you!
The black screen can't enter the system? Or the screen is not lit at all, if you can't enter the system, you can try to restore the factory settings with one click (press F11 when booting) or reinstall the system to solve the problem. If the screen does not light up at all, the hardware fault is relatively large, and it is recommended that you send it to the repair service center for testing and repair as soon as possible.
Hope it helps.
I am an HP employee.
If the above information does not solve your problem, you can continue to ask or visit the HP technical support webpage (

1. Try brightening the brightness of your computer screen. 2. Press the F2 button when you boot up to enter the BIOS interface to check whether it is displayed normally. 3. Connect an external monitor and press the key combination to switch the display.
4. Remove all external devices, take out the installed memory or other hardware, and then turn on the device for confirmation. If the above methods still cannot be solved, it is recommended to go to the after-sales service center for testing.
Hope it helps.

Why does HP laptop screen go black after booting up? How to solve it?
Hello, I am Xiao Ai, an electronic consultant, and I am happy to answer for you Please later, I am working hard to sort out the answer for you, and I will reply to you soon
The black screen of the power on is black.
This is a regular system crash, and you can try to replace it with a solid state. May you have a light when it's dark, an umbrella when it's raining, someone to accompany you on the road, and if there are no other problems, I wish you a happy life.
If there are other letters displayed on boot, you don't need to change to a solid state, just reinstall the system directly.
I can't see anything.
Broken master? This is a solid-state problem, and the motherboard is also possible, and you need to check the hardware.
If this is the case, you can only check the line, and there is no other way.

About 10,000 to buy HP's DV2744TX, buy a computer and look at the after-sales service, for example, do you have an after-sales maintenance station in your local area, HP has gold medal maintenance stations in almost all prefecture-level cities in the country, maintenance is very convenient, and it is also very convenient and simple to change the system, notebook I am personally disappointed in Japanese things, such as Toshiba notebooks a few years ago, the same model has a problem, in Europe and the United States is to find back, and in China it is only to provide patches, most of the Japanese companies discriminate against the Chinese, Moreover, the profits of Japanese goods are generally high, such as automobiles, Toyota is the world's No. 1 profit, and General Motors' cars are the world's No. 1 sales.
