The laptop overheating alarm can t be turned on, and the maintenance says that the virtual soldering

A kiss on a cold day should be a blazing flame!

Motherboards usually have temperature protection, which automatically shuts down the power to protect the hardware device in case the heat dissipation capacity is insufficient and the temperature is too high. You can try to remove the battery and put it back on. Or ask for after-sales.

The black screen failure after overheating and crashing is mostly caused by overheating and virtual soldering of the graphics card, and you need professional maintenance personnel to help you try to weld the graphics card, other common reasons: the memory is loose or there is a problem with the memory itself, reinsert the memory or try to change the memory; The power supply chip of the motherboard is soldered or aged, the screen cable is loose or the motherboard short-circuits the power supply circuit of the screen; Graphics card, south bridge, north bridge BGA packaging chip virtual soldering or damage, generally there are more virtual soldering, just add soldering. Notebook hardware questions answered.

Answer: The computer is too hot to turn on, you can use an electric fan to blow the chassis to cool down, and you can turn on the computer after cooling down, or it may be that there is too much dust in the chassis that causes poor hardware contact, clean up the memory card and graphics card in the chassis, and then try to turn it on. If it still can't be turned on, it may be that the computer motherboard and CPU are burned out and need to be repaired by professionals.

A big reason is that the motherboard burned out.

Question: The computer I just bought was used on the first day today.

You may be a problematic machine.

Question: Is it normal to dissipate heat for almost an hour.

Question: Is this a problem with the machine, it won't be like this with the new machine?

So your machine is a machine with quality problems.

Complaints can be made. Asking a question, and after only a few hours, the touchpad can't be used.

Question: Jingdong official *** shouldn't buy it?

No, then why did you have so many problems on the first day of buying, which means that there is a quality problem with his machine.

Question: Generally, computers don't dissipate heat for so long.

Fan, check if the fan is too dusty! The speed of the fan will affect the CPU cooling effect of your computer, and the high CPU temperature will cause a crash!

If the computer screen is black, check the graphics card first, and then take a look at the memory module! Then check if there is any problem with the hard disk, and if there is no problem, rewrite the master boot record. If the hard drive is fine, if you have tried all of the above and it doesn't work, you can only reinstall it.

1. Press F2 or F12 to enter BIOS;

2. Check whether the BIOS can recognize the HDD;

3. If you have an HDD, you can disassemble the hard disk and re-plug it and try to enter the system;

4. In addition, press F8 to enter the system from the mode;

5. If none of the above works, you should need to reinstall the system;

I took a wet towel and put it on it, and the fan blew it.

It should be the motherboard burned, go fix it!

It's better to go to the after-sales office to take a look, and if it doesn't work, replace it with a new one

The HP V3000 and DV2000 are flawed in their design, and many graphics cards have problems.

Because of the heat dissipation defects of these notebooks, after repairing the graphics card, it is necessary to modify the heat sink and fan circuit to prevent the recurrence of graphics card problems. This is absolutely not possible to only repair the graphics card or change the motherboard, you must modify the heat sink and fan circuit and then match a heat dissipation base, because the temperature is too high is the essential reason, only in this way can it not be **.

Non-Beijing netizens can also ask questions, don't be polite, hehe. You can find me in Beijing, and you can find a trustworthy repair point in other cities.

HP's notebook is LG; In the past, I used HP in the company to send repairs 2-3 times a month, and we are platinum customers, they should provide door-to-door service, and the service quality is also poor.

Your computer should have burned out the graphics card, since most computer graphics cards and motherboards are integrated, so if you are within the warranty period, you should take it and repair it! (Notebook repair is generally to replace the motherboard (all integrated), that is, full replacement, generally cannot be repaired) If the shelf life is exceeded, the major repair is about 1000-3000. See for yourself!

After the expiration date, you might as well buy a new one! Don't buy HP, it's better to buy Lenovo than HP, and you have the money to buy IBM (there's nothing to say about this), Fujitsu, sorry. No money Samsung, Dell.

Other brands have a bad impact. I use Samsung Q70, a few months ago I was full of water on the machine will be hot, and the result is broken motherboard, I didn't expect Samsung to say that it can help me change, buy it for 2 years, free change, not much nonsense, the area is Shanghai. (Samsung seems to have a different shelf life for each part - - Later, I bought a radiator under the computer, which is very effective, and can basically ensure that the machine is cool underground, don't forget to buy a radiator after you get it!)

The heat dissipation is not good, it is recommended that you deal with the CPU fan first, if not, you have to repair the motherboard graphics card, this graphics card BGA packaging chip is overheated and damaged by virtual soldering.

If you suspect high temperature power-off protection, clean the inside of the machine and try it.

At the same time, MS is a symptom of the early stage of virtual soldering of the graphics card, if so, it won't turn on after a while, only the fan will turn.

The notebook needs to be cleaned.,Dust it after the computer is cleaned.,It's estimated that it's OK.。。

Remove the fan and clean it up.

It's about this price.,But 4,5 years ago, it was too cost-effective to spend 200 yuan to repair.,The value of your graphics card is estimated to be no more than 200.,And this kind of repair rate is very high.,It's recommended to sell it for a new one.。

Due to the overheating of the graphics card, the pins of the graphics card are sweating, and there are two situations when the graphics card is soldered

1. The computer screen has a blurred screen, or the screen has many layers of screens.

Second, serious cases will fail to turn on. This has nothing to do with the graphics driver. If it is a discrete graphics card, you can change to a graphics card.

2. I have changed the graphics card of the notebook, the general graphics card is not much money, and the salary when welding is more expensive, only the salary is about 150, and it is necessary to use a special machine for welding.

2. When I change to a GT310M graphics card, even the graphics card material cost is about 350 yuan. It's a bit expensive to charge you 300 yuan for only wages.

The graphics card will not be damaged after the virtual soldering is repaired. Unless you have something wrong with your memory.

Did he change the memory for you?

Software and hardware incompatibility have not been heard to cause this problem.

I think it's still a problem with your graphics card, did he change what chip, causing you to not be able to install the driver?

The protagonist of the NVIDIA GeForce 8600M GS graphics card door. My previous book was also this model.,Shenzhou customer service said it couldn't be repaired and replaced with a barebones.。 It's a barebones system for HP600, and the graphics card is 8400M GS Although the performance is much lower, it is equivalent to a new computer, which is also very good.

System Problems Don't use win7

You just plug in the graphics card, and you won't get stuck.

Didn't you have a drive disk when you bought a graphics card, just play the original driver.

The landlord should be warranted in this situation, and how many times it is broken should be repaired for you free of charge. If the warranty period is over, I recommend replacing it directly, if it is not a high-end notebook, it should be normal to replace it every year, after all, there are various defects in the design of the notebook. It is difficult to effectively solve the problem of poor maintenance, and the virtual soldering of the graphics card is one of them.

Replacing the graphics card chip with a new one can solve the problem better, but replacing the graphics card chip is more expensive. If you don't take good care of it or use it very hard, the service life of the new chip is still not guaranteed.

If the landlord doesn't want to change the computer, then change the chip and pay attention to playing, usually pay attention to putting it away when not playing, and try not to overheat the notebook or heat up seriously. If you play with a little care, it shouldn't be a big problem.

Generally, the computer city can help you weld, but there are charges, it is recommended that you find an acquaintance who has no welding, it will be easier to find someone to weld yourself, and this is not a very difficult thing, generally welding will be solved. View the original post

What are the specific fault manifestations? If the screen is displayed, it is mostly a system and hard disk problem, power-on no display failure, this situation is mostly caused by loose aging of components or chip virtual soldering damage, the machine is damp and shocked or long-term overheating will lead to this situation, it is recommended that you find a good technical maintenance master to help you overhaul, common reasons: loose memory or memory itself has problems, reinsert the memory or change the memory to try; The power supply chip of the motherboard is soldered or aged, the screen cable is loose or the motherboard short-circuits the power supply circuit of the screen; Graphics card, south bridge, north bridge BGA packaging chip virtual soldering or damage, generally there are more virtual soldering, just add soldering.

If the laptop fails to boot normally, you can troubleshoot it as follows:

1) First remove the battery, unplug the power plug, press and hold the power button for about 5 seconds, then plug in the power to see if it can turn on normally, if it still can't turn on, continue the following steps.

2) Remove the battery, unplug the power plug, and open the back cover screws with a Phillips screwdriver. There is an opening on one side of the cover, and the cover can be removed by gently cocking it along the opening with a screwdriver.

3) After removing the cover, find the memory module, and use a screwdriver to gently remove the clips on both sides of the memory module, so that the memory module can be released. Gently remove the memory module and wait a few moments before putting it back on.

4) Cover the cover plate in reverse according to the disassembly method, install the battery, and turn on the power button to restart.

Repeat the entry into the system several times, indicating that there is a delay process in entering the system;

Generally speaking, it takes time to cool down in the case of overheating, which is the mechanism of the delay process;

The parts of a laptop that are most prone to high heat and take time to dissipate heat are its power supply part, as well as the CPU;

According to this principle, it is necessary to first focus on the power supply of this book, that is, the DC DC conversion circuit, and the circuit is most susceptible to high heat is the power adjustment tube, if the characteristics of the adjustment tube are poor, or the thermal stability performance is not good, there will be the phenomenon described by the landlord; In addition, if the CPU is overheated, then the waiting time will be very short, generally not more than 5 minutes, which is different from the adjustment tube takes about 10 minutes.

In addition, the black screen, the graphics card is damaged, the virtual soldering, the loosening, and the overheating can all have the problems you mentioned above, and the graphics card inspection should be sent to a special repair shop, and it is not good to check it yourself

Happy online gaming

Ha ha... Look at luck.

Check the computer well, from the motherboard to the hard drive, to the power supply.

Is it completely unresponsive when you press power on? Unload the battery and put it back on and take a look!

Step 1: Start the computer in safe mode to see if it can boot, if it can't boot, it may be infected with a virus, system files are missing, the operating system is damaged, the hard disk has bad sectors, the hardware device has a conflict or the hardware has a problem, go to step 4; If you are able to start Safe Mode, it may be caused by the hardware driver being incompatible with the system, the operating system is faulty, or it is infected with a virus.

Step 2: Then run the antivirus software, if there is a virus, it may be caused by a virus, restart the computer after the antivirus, if it is not normal, you need to reinstall the operating system.

Step 3: If no virus is detected, you can use the "System Restore" function of the operating system to restore the system, and if the system is normal after the restore, the failure is caused by system corruption. If the fault persists, it may be caused by the incompatibility of the device driver with the system; Then delete the drivers of the sound card, graphics card, network card and other devices, and then install the drivers one by one, restart the computer every time you install a device, to check which device's driver caused the failure, find out, ** the new version of the driver of the faulty device, and then install it.

Step 4: If you can't boot from safe mode, then reinstall the operating system with the installation disc. If you can install the operating system normally, go to 7 steps; If there is a failure when installing the operating system, such as a freeze, blue screen, reboot, etc., which causes the system to be unable to be installed, it should be caused by a hardware problem or a poor hardware contact.

Step 5: Then clean the dust in the computer, clean the gold finger of the memory, graphics card and other equipment, reinstall the memory and other devices, and then reinstall the operating system.

Step 6: If you still can't install the system, it could be a malfunction caused by a hardware issue. Then use the replacement method to check the hardware failure, and replace the hardware after finding it.

Step 7: If the operating system can be installed normally and the fault disappears after installation, it is a fault caused by corrupted system files.

Step 8: If the fault persists after installing the operating system, it may be caused by bad sectors on the hard disk or the device driver is incompatible with the system. If you boot your computer in safe mode, if it doesn't boot, it's a malfunction caused by bad sectors on the hard drive.

Then use NDD Disk Utility to repair the bad sectors.

Step 9: If you are able to boot Safe Mode, it is caused by the incompatibility of the device driver with the system. Then delete the sound card, graphics card, network card and other devices, and then install the drivers one by one, install one by one, and start one at a time to check which device's driver is causing the failure.
