Automatic shutdown of notebook computer

This article is about the laptop computer shutdown problem Solving

One, software





1. Virus damage


is typically a "shock wave" virus that has caused serious damage to the global computer for a period of time, and also prompts the system to start automatically in 60 seconds after the attack. In fact, early in the DOS era there are a lot of viruses can automatically restart your computer.





for virus damage, we can use the latest version of antivirus software for antivirus, the general will find the virus exists. Of course, there is also a possibility that when you are on the internet has been malicious intrusion into your computer, and placed a Trojan horse program. This allows the other person to remotely control all of your computer's activities, including, of course, getting your computer restarted. For some Trojans, not easy to clear, it is best to reinstall the operating system.





2. System file Corruption





when the system files are corrupted, such as the fonts under the Kernel32.dll,win98 fonts directory under Win2K, and so on, when the basic files are corrupted, the system will not be able to complete initialization and forcibly reboot when it starts. You can do a test, the WIN98 directory of the Font "FONTS" to try to change the name. When you turn on the machine again, our computer will continue to start repeatedly.





for this failure, you can only overwrite the installation or reinstall because you cannot get to the normal desktop.


3. Timing software or scheduled task software works





If you set up a restart or load some of your work programs in the "plan taskbar", the computer will start again when the timing comes. In this case, we can open the "Start" item, check that there are not familiar with their own execution files or other timed work procedures, shielding them and then power-on check. Of course, we can also enter the "Msconfig" command directly in "Run" to select the startup item.





II, Hardware





1.
of voltage instability in mains

General household computer switching power supply operating voltage range of 170v-240v, when the mains voltage below 170V, the computer will automatically restart or shutdown. Because of the fluctuation of the mains voltage we sometimes do not feel, so we will mistakenly think that the computer inexplicably automatic restart.


Solution: For regular power supply instability in the region, we can purchase UPS power or 130-260v wide switching power supply to ensure the stability of the computer work.





2. Poor quality of plug or outlet, bad contact


market power plug in most of the quality is not good, the internal contact is the use of manual welding, and often used acid flux, so easy to cause in the later use of solder point oxidation caused by the circuit breaker or the FireWire and 0 lines between the leakage. Because of the manual welding and because of the poor elasticity of the phosphor brass sheet, in less than a long time will be easy to lose elasticity, resulting in contact with the host or monitor power plug bad and produce a larger contact resistance, in the long hours will be a lot of heat and lead to a virtual connection, then the performance for the host reboot or monitor black screen flashing.


also has a wall socket that might be used in our home, most of the wall socket installation is not the use of professionals, so the wiring inside the socket is not standard, especially these sockets if we often use high-power electric heater when it is very easy to cause the internal heating oxidation of the virtual connection and the formation of intermittent power, Causes the computer to reboot or the display blink phenomenon.


Solution:


① do not want to save money and buy cheap and not the beauty of power supply, buy some brand power plug, because its internal machine is automatic installation crimping, no manual welding.


② for the problem of whether it belongs to the inside of the wall socket, we can change the host to a wall socket and try to see if the same automatic restart problem exists.





3. Power shortage or poor performance of the computer's power supply


This situation is also more common, especially when we add new equipment for their own host, such as the replacement of high-end graphics card, add a burner, added a hard disk, it is very easy to appear. When the mainframe is working at full speed, for example, run a large 3D game, high-speed burning or ready to read the disc, just started, the two hard disk on the copy data, may be due to the instantaneous power supply power shortage caused by power protection and stop the output, but because when the power stop output, the load is reduced, when the power is restarted. Because the recovery time after protection is very short, so give us the performance is the host automatic restart.


also has a situation, is the main engine switching power supply performance is poor, although the voltage is stable also within the normal allowable range, but because of its output power harmonics content is too large, will also lead to frequent host of the crash or restart. For this case, we use a multimeter to test its voltage is normal, it is best to replace a good power supply for replacement removal.


solution: Now for high-quality high-power computer power.





4. Main engine switching power supply plug loose, bad contact, no tight


this situation, most will appear in the DIY machine, the host power supply cable with no 3C certification, and power outlets do not match. When we shake the table or touch the host will appear when the host automatically restart, usually accompanied by a slight electric spark "PA" sound.


Solution: Replace the high quality 3C authentication power cord.





5. The motherboard's power ATX20 socket has virtual welding, bad contact


This fault is not common, but it does exist, mainly in the normal operation of the mainframe, the left and right to move the ATX20 pin plug to see if the host will automatically restart. At the same time also to check the power of the 20-pin plug inside the reed has oxidation phenomenon, it is also easy to lead to contact resistance, poor contact, causing the host to panic or restart. Sometimes also need to check the 20-pin plug the end of the connection line, is reliable.


Solution:


① if it is the motherboard solder point virtual welding, directly with the soldering iron can be. Note: In the motherboard, hard disk, graphics cards and other computer board welding, must be good grounding soldering iron, or unplug the power plug when welding.


② If the problem is a power supply, it is best to replace a good power supply.





6. CPU Problem


CPU internal part of the functional circuit damage, two cache damage, the computer can also start, and even into the normal desktop for normal operation, but when a special function will restart or panic, such as drawing table, play VCD, play games and so on.


Solution: Try to screen the two-level cache (L2) or the first-level cache (L1) in the CMOS, see if the host can run normally, or simply use a good CPU to replace the elimination. If the screen can be normal operation, or can make do with the use, although the speed is slower, but will be able to save money.





7. Memory Problem


If a chip is not completely damaged on the memory bar, it is likely to pass the self-test (most of which will have a post), but at run time will be due to the high memory value caused by the failure of the function and unexpectedly restart. Most of the time when memory corruption, open the opportunity to alarm, but the memory is not damaged after the alarm, no power failure is still available. It is best to use the elimination method to quickly determine the fault area.





8. Optical drive Problem


If the optical drive is damaged internally, it can also cause the host to boot slowly or fail the self-test, or it may be suddenly restarted during work. For the latter case, if we have replaced the optical drive, it is likely that the power consumption of the optical drive is different. What you need to know is that although the ATPI interface of the optical drive is the same, but the different manufacturer's PIN definition is not the same, if we have a problem with the hard drive line, it may produce for a certain brand light driven with no problem, but the other brand optical drive can not work, which requires attention.





9. Reset Key Quality problem


If the reset switch is damaged and the internal reed is always in the short position, the host will not be able to power up the self-test. However, when the reset switch is less flexible or the button on the chassis is not easy to bounce, it appears in use because of occasional touch of the chassis or a sudden reboot of the host in the normal use state. Therefore, when the reset switch can not be moved freely, we must carefully check, it is best to replace the new reset button switch or the external button of the chassis lubrication treatment.


also has a situation, because the reset switch leads in the case of welding insulation layer off too much, plus the use of many times in the process of unpacking will cause reset switch line too close to cause collisions, resulting in automatic restart of the host.





10. Automatically restart
when accessing the network card or the interface, serial port and USB port to connect to the external device

This situation is generally due to peripheral problems, such as the printer's mouth damage, a foot to the ground short-circuit, US


Computer automatic Restart panic slow unable to open file (software-induced failure)


on the optimization of the Master, Magic Rabbit application


(go here to download: The official edition of Windows Optimizer 5.84,


1: Cleaning up the maintenance registration information with the optimized Master System (do not backup) and clean up the garbage files.


2: Open Optimization Master Find the file inside this backupregistry delete all


3: Do not need to back up the registry


4: Software intelligent Uninstall (delete) software, compared to delete a little cleaner. However, it is important to note that the uninstall (delete) software is best to check out the content it has to delete, because, sometimes it will also mistakenly delete what should not be deleted or even system files. In this case, you exit the optimization master, and then delete it later.


5: Background optimization with its "Background service optimization". Set Enable automatic manual.


6: Use the system disk doctor to check the disk.


7: It's good to use its "disk edge storage" To adjust the virtual memory 3lian.com


8: Its default general can be used


9: It is particularly convenient to use it to check system information.


10: Then use the Super Bunny Magic set point to clear the trash point purge record and clear the file (select All) point cleanup.


11: Point Bunny Software Point Registry Optimization to remove garbage.


12: Point Utility Super Bunny System rescue Point Delete backup record delete backup record.


13: Dot Super Bunny IE assistant fix ie.


Point Super Bunny repair specialist repair IE


(Note: When using these two software, close all open programs)


I personally suggest: generally use the above several functions, the other is not to use, with other functions will cause system failure.

The use of
magic Rabbit is similar to that of the master of optimization. However, it is particularly good to fix ie.
