Acer 4736ZG notebook automatically power off when turned on, what is the problem that it can t be tu

Reasons and solutions for computer not turning on:

Step 1: First of all, according to the specific situation analysis, if there is no power response directly, then check whether there is a power supply, poor contact, hardware and other problems, go to the second step, if it is not possible to enter the system may be operating system or software problems to go to the third step.

Step 2: Check whether there is a power supply problem, first see if the power supply is not plugged in well or there is a problem with the plug, if you are using a battery, then plug it in and try again. You can go to a friend or go to a computer repair shop or sales store to find the same model of power supply to try it.

After replugging the power supply, press the power button again, and if it still can't be turned on, then press it for a while. If you change someone else's power supply to turn on, it means that there is a problem with the power supply, if it proves that there is no problem with the power supply, it may be the hardware reason, go to the fifth step.

Step 3: Go to the last correct configuration to adjust, turn on and press and hold F8, enter the advanced options page, select "The most recent correct configuration", and press Enter. If it can enter the system, it may be caused by viruses, incompatible hardware drivers with the system, or operating systems.

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, restart it after removing the driver, if there is still a problem, then go to the next step.

Step 4: Repair and install or reinstall the system, set "Optical Drive as the first boot device" in the BIOS, then insert the system disk, and press the R button to perform "Repair and Installation". If the fault persists, just at the beginning of the system, select "One-click GOST to restore the system" or use the system disk to reinstall the system.

Step 5: Check whether there is a hardware problem, disassemble the notebook to see if the hardware is loose, generally the hardware is not plugged in well, there will be an alarm sound, the long sound continues to sound 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 can't be started at this time, it is best to send it for repair, and the professional will check whether there is a problem with the hardware one by one.

If it is not a heat dissipation problem alarm shutdown, then it should be a motherboard problem.

There is no charge for going to the official after-sales point for testing. But if you want to repair it, it will cost money, how much the phone bill depends on what to change, if it is to change the motherboard or something like that, I suggest that the landlord or a new book. Even if you take it to a small place to repair it and spend a few hundred dollars, I don't think it's worth it, 09 years old notebooks, you can buy one for a few hundred dollars in the second-hand market, and you can't sell it at all.

The money for repairing it is estimated that it is enough for you to buy a second-hand one for some more time, and after the notebook is repaired, no one can guarantee how long it will last.

To sum up: It is recommended that the landlord buy another one directly, and the general notebook cycle will be eliminated in 3-5 years. Now XP has said goodbye.,It is recommended that the landlord change to a new one.,Since playing games,Sell an i5.,Now the new architecture,It's much better than the previous performance.。

Just imagine that the 9800GT of the year is compared with the current general graphics card, and it has become scum.

Summary. Not being able to turn on the machine is generally a few phenomena.

First, there is no response when you press the power button - check the external power supply first, and then see if the motherboard is powered on, there will be LED lights on the motherboard. Second, the motherboard does not turn on when powered on - it is generally a problem of insufficient power supply and switching circuits. If possible, use the meter to measure.

Third, there is no signal from the fan to the display, and there is no alarm from the host, which is mostly a memory problem, followed by the graphics card, and there are very few problems with the graphics card. If there is a problem with the graphics card, the alarm will be called.

Fourth, the above three are fine, and the display screen has a small dot that keeps beating Not only the system, but the computer does not recognize the system files. It is usually a system damage or a faulty hard disk data cable.

Acer computer 4738 finished the system and suddenly couldn't turn on.

Hello dear, I am answering this question for you, please wait patiently for a while, and the answer will be revealed for you immediately, please don't worry! ~

How to fix it. Acer computer 4738 finished the system suddenly could not turn on, Acer computer 4738 finished the system suddenly could not turn on.

Wait a minute.

Hurry, hurry, hurry, hurry.

Not being able to turn on the machine is generally a few phenomena. First, there is no response when you press the power button - check the external power supply first, and then see if the motherboard is powered on, there will be LED lights on the motherboard.

Please compare it based on the above.

Common reasons: First, the memory is loose or there is a problem with the memory itself, try to reinsert the memory or change the root memory; Second, the motherboard power supply chip is soldered or aged, the screen cable is loose or the motherboard short-circuits the screen power supply circuit; Third, the graphics card, south bridge, and north bridge BGA packaging chips are soldered or damaged, and there are generally more cases of virtual soldering, so it is good to add soldering.

The lights that appear after doing the system are on.

What about people. You can turn off the power first, remove the memory from the back, and try to install it from the new. If it still doesn't work, it should be a problem with the motherboard, and you can only go to the repair station for repair.

Then there is a problem with your memory, and there is an alarm. Just change the root.

You can follow the following tips to operate, I hope mine is helpful to you! Cause Analysis]:

It is generally caused by excessive temperature and unstable hardware.

Solution]:

Solution 1: Check the temperature by the hardware master.

Open [360 Security Guard] - [Functions] - [Master Lu] - [Temperature Monitoring] to check the temperature, if there is a red display, or Master Lu sends out an alarm sound, it is recommended to detect the heat dissipation of the machine. (See Figs. 1, 2, 3).

High computer temperatures are generally caused by poor heat dissipation inside the machine. It is recommended to find a professional physical maintenance shop from the local area for dust removal and add heat dissipation silicone grease. Users who have no experience in disassembling the machine are advised to operate cautiously to prevent improper operation from causing hardware damage and bringing you unnecessary economic losses from the bump.

If it is a notebook during the warranty period, it is recommended to go to the local after-sales center for maintenance, otherwise it may affect the future warranty service after disassembly.

Solution 2: Hardware damage.

If the above methods do not work, it is recommended to reinstall the operating system for testing. If the temperature is normal, the operating system has been newly installed, the problem is still the same, the reason for the automatic shutdown and restart may be caused by the hardware, the power supply failure caused by the lack of power supply, frequent restart and shutdown or the motherboard capacitor is caused by problems, it is recommended to go to the hardware repair station for detection and replacement, you can also log in, or use the computer rescue - merchant rescue to find the nearest merchant to you.

Acer 4736ZG notebook, power off when turned on, turn on n times to enter the system, and it will be powered off again not long after.

Judging from the description of the problem, it must be caused by hardware damage.

1. It may be a power supply problem, you can change an external power adapter or battery, and turn on to see if it can be turned on normally.

2. It may be a hard disk problem, you can try to replace a hard disk and see if it is solved.

3. Finally, the motherboard is damaged, which may be caused by serious aging or damage to some components of the motherboard.

In this case, it is best to send it for after-sales maintenance or find a repair shop with a good reputation for inspection and maintenance.

After-sales is generally to replace the motherboard directly, and the price is about 1000; The repair shop repair price is around 300.

It's the motherboard that needs to upgrade a BIOS.,My E1-471 is too.,Normal use.,There's a month of useless boot that's it.,Open it several times before you can enter the system.,I got the after-sales service.,10 minutes to get it.,If you're familiar with the BIOS, you can handle it yourself.,But don't take risks if you're not familiar with it.,

For heat dissipation problems, maintenance of the fan will be fine.

Is it that the power cord is not in good contact and take it for testing.

I guess the motherboard is broken, so take it to fix it, but it's not worth it. Consider buying a new one.

It seems that you are already very professional, in case it doesn't work, throw it away and buy a new one!

If you're not playing big games or 3D graphics, I can tell you for sure that the power supply isn't broken.

I've dealt with this kind of problem much better.

Generally, automatic shutdown is a problem of CPU overheating.

There are three types of CPU overheating issues:

1: The CPU is broken. Hardly possible, exclude.

2: The CPU fan is broken, it is possible, but it is generally found. You can open the case and turn it on to see if the fan is rotating and whether the speed is normal.

3: Silicone failure between the CPU fan and the CPU. This is common, and it is easy to ignore, silica gel is a layer of gel between the CPU fan and the CPU, its thermal conductivity is good for heat transfer, if this thing fails, then the temperature of the CPU still cannot be dissipated, resulting in the CPU temperature is too high, and then triggers the CPU automatic protection system and power failure.

Hope it helps.

I suspect that when you dismantle it, you moved something, especially to check if the CPU heatsink is loose.

Dismantle it yourself, take out the fan, drop a drop of special computer fan lubricating oil, the computer city is sold, not expensive.

There are many common problems in the repair of this machine, which is basically the problem below.

1. BIOS problem, first brush a BIOS to have a part of this power-down fault will be good.

2. If there is a problem with the graphics card, you need to repair the graphics card chip and get the heat dissipation done.

3. The heat dissipation problem, which you can eliminate by testing the highest temperature by Master Lu.

Answer any troubleshooting notebook hardware issues.

You should be, CPU temperature is too high, block protection, auto-shutdown laptop heating is a common phenomenon.

It's been three years, the notebook should be out of warranty, and there's no need to go to after-sales if it's out of warranty, it's expensive to death, and it can't deal with the problem.

It is recommended to find a notebook for repair and replace it with a set of heat dissipation components, so that the effect should be much better!

That's about a hundred.

Fan rotation does not mean that the heat dissipation is good.

It should be that the temperature is too high, it is recommended to clean the air duct, and change the thermal conductive glue, if it is not good, you can only change the fan.
