Hello, thank you for choosing HP products.
According to your description, I suggest you refer to the following information:
1. Your laptop is turned on with a black screen, and the screen is not bright as if it is not turned on. You can recall what happened suddenly after the operation, such as whether you have added new memory recently or made other hardware changes.
2. Please use the battery or power adapter alone to power the notebook to see if it can be turned on normally.
3. If you haven't done anything special, you can't start the machine by using the battery or the power adapter alone. I suggest you try to turn it off and let the machine stand. The method is as follows:
(1) Remove the power adapter, battery and other external devices, such as USB mouse.
(2) In the absence of power supply equipment, you press and hold the power-on key for about 1 minute;
(3) Then don't connect the power equipment, and let it stand for about 30 minutes;
(4) Don't plug in the battery after standing, just use an external power supply, connect the machine end of the power supply first, and then connect the socket to see if it can be turned on.
4. If none of the above methods can solve your problem, it is preliminarily judged that this situation may be caused by motherboard failure or poor cable contact. In order not to delay your use, please contact your local HP Gold Service Center for testing and handling.
You can check the nearest HP Gold Service Center through the following website:

2. What's the matter with HP notebook booting or not?
In this case, you need to know why the computer can't be turned on, and then solve the problem.
Generally, there are the following situations: the first symptom is that the computer does not respond after pressing the power button of the computer, and the most common reason is the hardware problem: the hardware problem can be specific to various computer components and connecting wires, which can be found by the following methods. First, the aging of computer power supply causes voltage instability and insufficient power. The common symptom is that the computer power supply is dead in an instant.
At this time, you can try to unplug the power cord and plug it in again. If not, read on.
The second is the problem of connection. Since the power supply is not good, you can try to plug the hardware cable in the computer case into the motherboard again. Loose cable can also cause the computer to turn on and not respond. Third, improper storage of computers. Compared with the old computer, the dust in the computer case needs to be cleaned regularly, otherwise the dust on the motherboard, the dust on the cpu fan and the dust on the computer power supply may make the computer unable to start.
This is easy to solve. Just use a cleaning tool to carefully blow the dust off these places on the computer. Hewlett-Packard (HP) is one of the largest information technology (IT) companies in the world, founded in 1939 and headquartered in Palo Alto, California, USA.

3. What if the HP laptop is broken?
Hello, thank you for choosing HP products.
Notebook phenomenon may be related to hardware operation. After that, I suggest you remove the notebook and connect it to other devices (if there is a built-in CD-ROM drive, you can take out the CD in the CD-ROM drive). If other hardware such as memory is added inside the notebook computer, it needs to be removed.
Remove the battery and external power supply, completely cut off the power supply and let it stand for half an hour to release static electricity, and then turn on the power supply to see if it can resume normal display and use. If it cannot be improved, you can try to replace other power adapters or other power sockets of the same model for power supply.
Still can't improve, take the time to contact HP Gold Service Center for detailed inspection and maintenance. You can check the nearest HP Gold Service Center through the following website:
It is recommended to call to confirm the specific schedule of the maintenance center. If the phone can't be connected on weekends, it is recommended to call from Monday to Friday. I hope the above reply can help you.
4. Is the HP laptop turned on or off?
Hello, thank you for choosing HP products.
1, please recall what happened suddenly after the operation, such as whether you have made any hardware changes recently (such as adding new memory) or connected external devices. If so, I suggest you restore the previous hardware configuration and disconnect all external devices to see if they can start normally. 2. Please use the battery or power adapter alone to power the notebook to see if it can be turned on normally.
If the problem still exists, I suggest you try to turn off the machine and let it stand. The method is as follows: (1) First, you remove the power adapter, battery and other external devices such as USB mouse. (2) In the absence of power supply equipment, you press and hold the power-on key for about 1 minute; (3) Then don't connect the power equipment, and let it stand for about 30 minutes; (4) Don't plug in the battery after standing, just use an external power supply, connect the machine end of the power supply first, and then connect the socket to see if it can be turned on. 4. If none of the above methods can solve your problem, it is preliminarily judged that this situation may be caused by hardware failure, such as motherboard failure or poor cable contact.
In order not to delay your use, it is recommended that you contact the local HP Gold Service Center and check the specific reasons before handling. You can check the nearest HP Gold Service Center through the following website: I hope the above reply will help you.
5. What's the matter that HP laptop suddenly won't open?
The laptop cannot be started for the following reasons:
1. Try the following first: take out all batteries and power adapters, press and hold the switch button for 30 seconds to discharge static electricity, wait for about 15 minutes, and then connect the power adapter separately to power on; If you can't boot, there are several reasons.
2. The first reason: the startup circuit of the notebook motherboard is faulty, such as clock, reset, power supply, MOS tube, etc. , which may lead to failure to start, black screen, I/O problems, failure to start the computer, black screen and so on. Solution: Send it after sale or go to a repair shop to repair the motherboard.
3. The second reason is that the memory and graphics card of the notebook are oxidized, which leads to poor contact between the memory slot and the graphics card slot, leading to boot failure and black screen. How to deal with:
4. Solution: Unplug the power supply, open the back cover of the notebook and take out the card slot of the memory. If it is not a discrete graphics card welded on the motherboard, take out the card slot, aim at the memory and the gold finger of the graphics card (where there are copper sheets), wipe it back and forth with an eraser, blow off the dust, and then plug it back in. After closing the lid, it is generally no problem to start the machine.
5. The third reason is that there is virtual soldering in the memory of the notebook graphics card, the performance of the main chip is degraded, the BIOS of the graphics card is disordered, and there is a problem with the control power IC, which will lead to the graphics card not working normally, that is, the graphics card is broken, naturally it cannot be turned on, and the screen is black. Solution: Jane, repair the video card or replace it.
6. Is the HP laptop turned on or off?
Under normal circumstances, if the safe mode cannot enter normally, your system will have serious problems. You can use HP's one-button recovery function (key F 1 1) to restore the system to the factory state. There are two prerequisites for using the key F 1 1 to restore the system. First, the machine uses its own pre-installed system; Second, the recovery partition has not been destroyed. If one condition is not met, the system recovery function cannot be realized.
If you have burned the system recovery CD before, you can use the system recovery CD to recover the system; If you haven't burned the system recovery CD, it is recommended that you contact HP's after-sales department to apply for the system recovery CD, and then use the system recovery CD to restore the system to the factory state. If there is no pre-installed system, it is recommended that you use the pure version of the system, install the CD-ROM formatted hard disk, and reinstall the operating system.
7. What's wrong with HP laptops?
The reason why the notebook can't be turned on and the solution;
First, there is no display when the notebook is turned on.
There is no response when the notebook is turned on, that is, after the key is pressed, the indicator light does not light up, the fan does not turn, and the computer does not respond. This kind of fault is generally a serious fault. This situation is common that the notebook battery is dead, or the external AC power supply is damaged or poorly connected.
Solution: Check the external AC power supply, or put the charged notebook battery into the notebook and try to turn it on. If it can be turned on, the external power supply is damaged. If not, it may be a hardware failure or a problem with the notebook power key. In this case, it is recommended to take it for maintenance.
Second, the laptop cannot boot into the system.
1. After the laptop is turned on, the power indicator is on, and if the display shows that it cannot enter the system. This situation is mostly caused by system failure.
Solution:
You can try turning on the computer and pressing F8 to enter the safe mode, and then enter the last safe configuration to try. If it still doesn't work, it is recommended to reinstall the system.
2, notebook into the system interface, restart or blue screen repeatedly.
This situation is probably because the internal hardware temperature of the computer is too high, such as CPU fan not turning, graphics card or other hardware failure. , or it may be a system problem.
Solution:
Reinstall the system.
3. After the notebook is turned on, the power indicator is on, but the display screen is unresponsive or you can hear the computer entering the desktop. This situation is caused by two problems, one is that the memory stick is loose, and the other is that the screen line connected to the monitor inside the notebook is in poor contact.
Solution: Send it for repair within the warranty period. After the warranty period, insert your own memory. Other hardware has poor contact, so it is recommended to send it for repair.
8. My HP notebook doesn't turn on, please ask an expert to answer.
This problem should be caused by too high CPU fan, or poor memory contact and long-term natural air oxidation of memory fingers. Blow it with a hair dryer for a few minutes, and the possibility of high CPU temperature is greater. The best way is to start the CMOS of the notebook to check the temperature. You boot and press DEL to enter the BIOS. Find the computer health project. Generally, the normal temperature is within 25~50℃, depending on the computer. If it is normal, I suggest you call HP customer service at 800-8 10-3888 for consultation.
Otherwise, do it yourself. If something goes wrong, HP will not recognize the warranty, and it will not be worth the loss. HP's after-sales service is strict, so you should report for repair first or take it directly to the maintenance station for repair. I have done computer after-sales service for several years before, and I have also done after-sales service for HP. I hope I can help you.
