Pressing the power off button has no response! The computer pressed the power button and did not res

There are many reasons for the failure of the computer to turn on the black screen, such as the display is damaged, the motherboard is damaged, the graphics card is damaged, the graphics card is in poor contact, the power supply is damaged, the CPU is damaged, etc. For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first.

1.Unplug the data cable connected to the monitor and the console, and turn on the power switch of the monitor separately. Generally, if the display is normal, it will display the manufacturer's information of the display or a prompt that the monitor is not connected, if it can be displayed normally, it indicates that the display is unlikely to be damaged.

2.Check that the exposure is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

3.If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound.

If the memory fault is ruled out, only the CPU and the motherboard are left.

What should I do if the computer does not respond after pressing the power button? What is the problem that the computer cannot be turned on after pressing the power button? Recently, several users have reported that the computer has not been able to turn on normally after pressing the boot button, and the following will give you an analysis of the specific reasons and solutions.

Dear Lenovo users, hello!

Hello dear Samsung users:

In order to understand and solve the problems of your mobile phone in a more targeted manner, it is recommended that you send your mobile phone to the nearest Samsung service center for testing, and the service center will determine the specific problems and accessories of the mobile phone according to the test results.

It is recommended that you apply for "appointment to store" on Samsung's official website to enjoy priority repair services

After the appointment is successful, please bring your machine, invoice and warranty card to the service center where you made the appointment on time.

Comments, suggestions, complaints, please click:

1. The keys are stuck (press the keys one by one, whether each button has elasticity).

2. The keyboard is wet and leaks (cleaning and drying the machine board).

3. The protection elements of the longitudinal and horizontal lines of the keyboard and the anti-interference capacitor leakage and short circuit (determined by measuring the resistance to the ground or the voltage of the keyboard contact).

4. Caused by the failure of the clamshell control circuit.

5. CPU virtual soldering or bad (replanting, replacement).

6. The machine board is disconnected.

Remove the battery or press and hold the power off button (more than 10 seconds).

I have also had such a problem as you, it is that the computer has a virus, you can't kill the virus, maybe your antivirus software itself is not good, try another antivirus software.

In addition, I will give you a way to not shut down normally, and see if it helps you.

The solution to Windows XP not shutting down properly.

In fact, the abnormal shutdown situation is a very common situation in windows98se. Common reasons are:

1.The operating system and motherboard do not have complete support for ACPI or APM.

2.Various hardware outside of the motherboard does not have adequate support for ACPI or APM.

3.Bugs in hardware drivers.

4.The motherboard's BIOS needs to be improved.

5.The system does not support rapid shutdown well enough (only for Windows 98).

Before shutting down, some programs with permanent memory show exit and conflict with the shutdown process of the system.

Virus. Disk subsystem failures, such as IDE drivers that are not compatible with the system well enough.

First go to the CMOS settings interface of the motherboard, and select Power

management will be pm

control

BYAPM is turned off, and after booting into the system, the computer is still restarted.

Then start WindowsXP, enter the control panel Power Management in turn, click the "Hibernation" menu, at this time, enable hibernation is not selected, then check "Enable Hibernation", but it still does not work.

Re-enter the power options in the control panel, click the "Advanced Power Management" sub-page, and the system displays: This machine supports Advanced Power Management (APM), and the use of APM can reduce the power consumption of the system. Enable advanced power management support is selected.

Don't hesitate to remove "enable advanced power management support", just consume a little more power, and can't shut down normally, how awkward. The next thing, of course, is the shutdown, ok
