Laptop won t turn on? How to solve the problem that the laptop computer can t be turned on

The true black screen is mostly a problem with the graphics card chip,If it is the chip of the NVIDA graphics card door, including the integrated graphics card, if you want to completely solve it, you must change to a new and improved version of the graphics card chip,Otherwise, it must be **,If it is not the chip of the graphics card door, such as ATI, you only need to add welding。

In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.

Method 1: 1. First of all, plug in the power supply and check whether there is a charging display. 2. If not, then it may be that the battery or power supply is broken.

3. We can try to pull out the battery and connect it directly to the power supply to see if it can be turned on. 4. If it can be turned on, it means that it is a battery problem, if it still can't, it is a power supply problem. (The power supply can only be replaced or repaired if it is broken) Method 2:

1. If there is a charging display, but it can't be turned on, then it may be another hardware problem. 2. At this time, we can try to disassemble the back cover and replug the memory, hard disk, graphics card and other devices. 3. If you use it for a long time, you can also clean up the dust by the way, and then try to turn it on after you finish.

Method 3: 1. If it still can't be turned on, then it may be a problem with the system. 2. If it can't be turned on at all, then it is recommended to use a U disk to enter the PE system and reinstall it.

Because important files can be backed up in the PE system) If you can't even reinstall the system, you can only send it to the store for repair, and the hardware should be damaged.

Here's how to fix it:Reason 1: Battery, power supply problems1, check all cables (including power plugs) to ensure that all devices are properly and tightly connected together.

2. Check whether the laptop has power (although most people will not make such a low-level mistake), because the notebook has a built-in battery, so it can be used without plugging in the power supply, of course, the time is limited, when the built-in battery is used up and not charged, it will cause the notebook to fail to turn on, at this time we just need to plug in the power to charge.

Reason 2: It may be caused by a virus infection, press and hold F8 to enter the advanced options page, select "Latest Correct Configuration", and then press Enter. After entering the system, run the anti-virus software, check and kill the virus, if there is a virus, restart the computer after the anti-virus, if it is not normal, it may be caused by the incompatibility of the device driver and the program, delete the graphics card, network card and other drivers, delete the driver and restart, if not, then rule out this reason.

Reason 3: Hardware problem: Disassemble the notebook to check whether the hardware is loose, generally the hardware is not plugged in well, there will be an alarm sound, the long sound continues to ring means that the memory module is not plugged in tightly, one long and one short means that the memory or motherboard has a problem, one long and two short means that the graphics card is wrong. If there is too much dust inside the notebook, it is best to clean it up first.

In addition, pay attention to whether it is caused by the new hardware, if it is normal before the replacement of the hardware, and it is not normal after the replacement, then check whether it is compatible. If it doesn't start at this time, it's best to send it for repair, and a professional will check whether there is a problem with your hardware one by one. Reason 4:

Display ProblemsIf the power supply** is working, but the screen is still pitch black, try connecting another monitor to your computer (you can borrow one if necessary) to make sure it's not a monitor issue.
