The computer can t be turned on easily, but it can be turned on, but it takes a long time

According to what you said, that is, it is easier to start in the case of a hot engine, I think there should be two points, first, the power supply problem, the power supply of the chassis is somewhat aging, and there may be a problem with some capacitors, resulting in the initial power supply is sufficient. Second, the main version of the problem, I have encountered this phenomenon before, to the store for a professional to check, said that there are cracks on the motherboard, it is not easy to energize, after the machine is hot, the current between the gravitational force, coupled with the thermal expansion of the motherboard, the contact between the cracks will be a little better. It is recommended to take it to a professional to see.

Clean up the system, C disk is best not to put things around, if the cleaning is ineffective, just reinstall it.

This phenomenon should be related to the BIOS system (you don't need it after POST)1Update BIOS (stable, not necessarily up-to-date)2Restore the default settings.

3.Replace the motherboard battery.

The capacitor is blown up, the motherboard or the power supply. This should be 80% possible, find someone who understands it to show you, just change the capacitor, okay, I want 40 points, haha.

It should be that the weather is cold now, and the temperature of the motherboard is a problem.

According to the situation I encountered, it is estimated that it is a problem with the power supply, check which end of the power plug is on the motherboard, and if you are not sure, go to the computer city to find someone to repair it.

Can you tell us more about that? How is it not easy to turn on.

There is no reason for the laptop to turn on: the laptop battery is dead, or the external AC power supply is damaged, or the power connection is poor.

If the power cord is in trouble, please check whether the power socket is normal and whether the power cord is normal. If you have a power supply problem with the case, please check whether there is a 5 volt standby voltage, whether the connection between the motherboard and the power supply is loose, if you can't measure the voltage, you can find a power supply to change it.

Motherboard problems, if there are no problems with the above two, then the possibility of motherboard failure is relatively high. First of all, check whether the connection between the motherboard and the boot button is loose and whether the switch is normal.

You can try shorting the switch with a wire. If not, you can only try replacing a motherboard.

In this case, don't worry, the hard drive is not necessarily broken.

When it is more likely, the storage conditions are not good, and the hard disk can be wet.

Use an eraser first to clean up all the gold fingers, especially the data cable interface.

Then turn it on and see if it's normal. It is still difficult to identify, do not turn off the power, continue to power on for a period of time, let the heat drive away the moisture, and it should be able to return to normal.

If the hardware is sealed, the problem should be on the circuit board.

If the computer is not used for a long time, it may be that the battery is broken, the battery is broken, and the computer cannot be turned on, or for a long time, will you forget that charging has caused the battery to lose power.

Procedure Method 11Put the computer host in a ventilated and backlit place, cool for an hour or two, and then connect it with the monitor, mouse, and keyboard, and test whether it can enter the system when it is turned on. 22.

Restart your computer and press the F8 key until the Windows Advanced Options menu appears. Use the arrow keys to select "Last correct configuration" or "Safe mode" to power on and see if you can enter the system. If you can use software such as 360 to clean and optimize your computer, repair the system, and restart your computer.

3.If you can't enter the system, shut down, open the chassis, remove the dust, and plug all the connections tightly and firmly into the system.

34.Check the motherboard battery, replace the motherboard battery, set the BIOS to factory defaults, and set the hard drive to the first boot.

Method 21: First check whether the external wiring of the computer is connected, and plug in each wire again to see if the fault is eliminated. 2. If the fault persists, then open the main chassis to check whether there is any excess metal in the chassis, or a short circuit caused by the deformation of the motherboard, and smell whether there is a burning paste in the chassis, whether there are burned chips on the motherboard, and whether the capacitors around the CPU are damaged. 3. If not, clean up the dust on the motherboard.

4. If the fault persists, then unplug the reset cable on the motherboard and connect it with other switches and indicator lights, and then use the short-circuit switch to see if it can be turned on.

5. If you can't turn it on, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on.

Hello landlord! If you can't open it for a long time, this may be a poor physical contact, and you can clean up the dust.

First check if the power supply is plugged in. If you don't turn on the computer for a long time, it is easy to cause the hardware in the computer to be wet, or there is too much dust, and it cannot run normally. This solves it!

Open the chassis to detect the chassis, the motherboard power supply problem, open the chassis, check whether the motherboard is connected to the boot button, whether the power cable is loose, and you can reseat it.

2.Battery problem, check whether the battery on the computer motherboard is still powered, if there is no power, you need to replace a battery.

3.For hardware problems, take out the memory module and graphics card on the host, clean up the dust in the case, and then use the eraser to wipe the memory module, and reinsert the gold finger of the graphics card.

4.If the computer still can't turn on after operation, then you need to take it to the computer shop for repair and inspection.

Hope it helps, dear.

The question display won't turn on.

Question: Is the computer good, is the monitor not lit.

You need to find the turn on button on the monitor, usually on the side of the computer, there is a clear switch symbol, press it, and the screen will light up. If these methods have not been solved, then you can also send your computer to a professional repair station for repair.

The computer is not used for a long time, and the circuit board of the computer host will oxidize and become moldy after being wet.

Leads to motherboard wiring.

The circuit is broken, so the computer will not turn on. Commonly used computers will not emit heat when the computer is running, and the motherboard is not easy to be damp and pulled.

The battery on the computer motherboard is too low, resulting in BIOS data loss, yes the BIOS does not recognize the computer hardware. If you don't replace the battery, you may not even be able to turn on the computer.

**Hint: You will shut down after 15 seconds. You can turn off the power, open the case, buckle the motherboard's battery, and wait a while to go up and test again.

Answer: Hello, most of this situation is that the chassis is too dusty, sealed, can't turn up, needs to be dusted, and then the battery is dead, you cut off the battery, put it for about 5 minutes, and press it.

Generally these are the two cases.

I tried to ask a question, but it couldn't turn on.

The memory card is dialed, and it doesn't work.

Sometimes it can be turned on once in a while.

It can run normally after booting.

Is the power supply too old.

In your case, it's either the battery or the power supply.

Do you turn the power fan when you can't turn it on?

Does it not work if the battery is taken off and pressed for a while? After pressing the power button, the fan doesn't turn, and the power supply fan doesn't turn either, right, that is most likely a power supply problem.

Question: The battery replay still can't be turned on, the indicator light doesn't light up after pressing the power button, and the fan doesn't turn.

I see that your chassis is very clean.

Go to a repair shop and try to change the power supply.

It's not that it can't be turned on, and it means that it has been turned on when you can get to this interface.

The problem should be that the coin cell battery on your computer's motherboard is dead, resulting in the loss of BIOS information, you have to press the del key to enter the BIOS, and then choose to restore the default settings, you can enter the system. Then it is recommended to buy a new motherboard battery and install it.

Go into the BIOS and then reset the BIOS, you can restore the original factory settings of the BIOS.

If you don't have to turn on the machine for a long time, there are many situations where there may be too much dust. It may be the system, but it doesn't work, and the system is redone.

Personally, it is recommended that you reseat all boards, especially memory modules, erase them with an eraser, and then put them back in. Then turn it on.

The computer is not used for a long time, the circuit components inside will be damp, so static electricity will appear, if it is better, there is no problem to directly cut off the computer power supply and press the switch a few times, and then connect the power supply, if you are unlucky, sometimes it may damage the circuit components!

Try the following steps to see if that solves the problem:

1.First of all, we open the case of the computer (only desktop computers, if you want a laptop, please find a professional staff to help you disassemble and check).

2.After opening the computer case, let's take a look first to check whether the battery on our computer motherboard is still charged. If there is no electricity, then we need to replace the battery.

3.Then let's take a look at whether the computer hard disk is damaged or something, if it is damaged, you can repair it yourself, if you can't, buy a new one.

4.Secondly, let's see if the memory module on our computer is loose, and if it is loose, we can plug it back in.

5.In addition, we need to blow the chassis with a tool to clean the equipment in the chassis a little, of course, it is best if you can also take apart some of the contents and bask in the sun, remember that the time should not be too long.

6.If you still can't boot after trying all the above methods, then we need to consider changing to a new motherboard.

The possible reasons why the computer can't be turned on for a long time and the solution to the square grinding car mu method:

1. The memory module is oxidized and rusted when it comes into contact with air. Unplug the memory module, gently wipe it with an eraser, remove the rust, and reinstall it.

2. The motherboard battery is insufficient. Replace the battery with a new one.

3. The motherboard graphics card is oxidized and rusted. Unplug the graphics card of the motherboard, gently wipe the memory module with an eraser, remove the rust, and reinstall it.

4. Accumulate too much dust. Use a hair dryer and a fine brush to remove dust from your computer.

The computer has not been used for a long time and cannot be turned on is due to the computer hardware burned out or the computer C disk system key loss and accidental deletion, the CPU fan turns to prove that the CPU and the CPU fan part is fine, you can reinstall the system to solve the problem, the specific steps are as follows:

1. Press the first part to wait to enter the main menu interface of the U disk installation master, select to run the U disk installation master win8pe anti-blue screen version, and press the enter key to confirm the selection:

2. After entering the U disk installation master win10pe system, the udisk installation master pe one-click installation tool will automatically open and load the win10 system iso image file gho installer, click select c disk as the system installation disk, and then click the "OK" button to continue:

3. After the pop-up message is a window, click the "OK" button to continue the operation

4. Wait for the win10 system ISO image file GHO installer to be released and automatically restart the computer

5. After the computer restarts, the system will automatically install the follow-up program, and set the relevant account parameters, and then enter the win10 application selection interface, click on the "desktop" application in the lower left corner, and then you can enter the genuine win10 desktop, as shown in the figure below:

Is the light of the monitor not lit? Or is the motherboard's light not on? Do the CPU fans turn?

Does the power supply's fan turn? You can do the basics first, dust off the main hardware such as the internal and graphics card, and reseat it. Is it wet?

You can use a hair dryer to blow it, but don't use too hot wind.

Take it to detect, memory problems, the laptop is wet, unplug the battery, and use the adapter to connect and turn on the computer separately.

The computer motherboard is damp.。。 There is a problem with the memory connection.

Wipe the memory on the plugging.。。 There is also the power connection between the motherboard and the chassis. Add a pad under the screws used to fix the motherboard.

Separate the motherboard from the chassis. Do not attach metal to metal. That's it.

Your computer might be hardware-protected. Try to cut off the power supply, unplug the battery, wait for 2 minutes, reinstall the battery, connect the power cord and plug it in, press and hold the power button for more than 10, the longer the better, then release the power button after the computer starts normally. If the computer still fails to boot, it can be concluded that the hardware is damaged, and it is recommended to send it for repair.

Causes and solutions

Method: 1. The inner DU storage strip is loose or damaged

Workaround: Erase the version with an eraser.

The memory module is cheated and reinserted into the right memory module; Replace the memory module.

2. Poor contact of the graphics card.

Solution: Same as memory method.

3. The main engine is short-circuited.

Workaround: Clean up the host and replug the wiring.

4. Motherboard BIOS problems.

The motherboard BIOS stores important hardware data, and if it fails, it can cause the computer to not boot.

Solution: Go to the motherboard BIOS settings page and restore the BIOS to the default value.

If you charge it for a long time, the battery may be overdischarged.

Please take a look at what's wrong with it.

This will happen when you don't use electrical appliances for a long time, so turn it on from time to time. Take it for repair.

The host is broken, and our family is the same, and it can't be turned on.

If the line is fine, it is 100% a power supply problem, take it to Zhongguancun and take a look!

The lithium-ion battery is losing money, so consider replacing the battery.
