What is the reason for the automatic shutdown of the notebook computer

Notebook computer automatic shutdown reason: Virus trojan damage, when the system core components damaged, the running computer may automatically shutdown. Trojan programs remotely control all your computer's activities, including getting your computer restarted.

What is the reason for the automatic shutdown of the notebook computer

Laptop Automatic shutdown Solution: Use anti-virus software, remove virus trojan malicious program, or directly reload the system.

The reason that the notebook computer shuts down automatically: The system file is damaged, such as the font under the Kernel32.dll,win98 fonts directory under the Win2K, etc. the basic files are destroyed when the system is started, so it can not complete initialization and forced reboot.

The solution to the automatic shutdown of a notebook computer is to fix the system through security software, repair the system, or reinstall the system.

Why the laptop shuts down automatically: Timing software or scheduled task software works, and if you set up a restart or load some of your work programs in the program taskbar, the computer will start again when the timing comes.

How to do the automatic shutdown of the notebook computer

Notebook computer automatic shutdown solution: For this situation, we can open the "Start" Item, check if there is no own unfamiliar with the implementation of the file or other timed work procedures, shielding it and then power-on check. Of course, we can also enter the "Msconfig" command directly in "Run" to select the startup item.

Notebook computer automatic shutdown reason: The chassis power supply is insufficient, DC output is not pure, dynamic unresponsive. Users or installed business often do not attach importance to the power supply, the use of low-cost power supply.

1, the power output power is insufficient, when running large 3D games and so on CPU resources larger software, CPU needs high-power power supply, power supply is insufficient and overload caused by power protection, stop output. When the power is off, the load is reduced and the power supply starts again. Because the protection/recovery time is very short, so give us the performance is the host automatic restart.

2, the power supply DC output is not pure, digital circuits require pure DC power supply, when the power supply of the DC output in the harmonic content is too large, it will lead to digital circuit work error, performance is a recurrent crash or restart.

3, the CPU workload is dynamic, the requirements of the current is also dynamic, but also requires rapid dynamic response speed. Some poor quality power supply dynamic response time is long, will also lead to frequent panic or reboot.

4, update equipment (high-end graphics/large hard disk/video card), the increase of equipment (burner/hard disk), power beyond the rated output power, will lead to recurrent panic or restart.

Notebook computer automatic shutdown solution: Now for high-quality high-power computer power.

The reason that the notebook computer shuts down automatically: the memory thermal stability is bad, the chip is damaged or set up error, the memory problem causes the system to restart the system to restart the probability to be relatively big.

1, the memory thermal stability is bad, boot can work, when the memory temperature rise to a certain temperature, it will not work properly, resulting in a panic or restart.

2, memory chip slightly damaged, the boot can pass self-test (set up fast start not fully detect memory), can also enter the normal desktop for normal operation, when running some I/O throughput of software (media playback, games, plane/3d drawing) will restart or panic.

3, the memory of the CAS value set too small can also lead to memory instability, resulting in automatic system restart. It is generally preferable to use the BIOS default settings and do not change them yourself.

Laptop Shutdown Solution: Use the heat sink or fan to cool the computer, or replace the memory.

Why the laptop shuts down automatically: High CPU temperature or cache damage

1, the CPU temperature is too high often cause protective automatic restart. The reason is too high temperature is due to the chassis, CPU heat dissipation, the cause of poor CPU heat dissipation: heat sink material heat conductivity is low, radiator and CPU interface between the foreign body (many for quality assurance posts), fan speed is low, fan and radiator dust too much and so on.

2, P2/P3 motherboard CPU under the temperature probe damage or P4 CPU internal temperature measurement circuit damage, the motherboard on the BIOS bug in a special condition of the temperature is not allowed, CMOS set the CPU protection temperature is too low, etc. will also cause a protective reboot.

3, CPU internal secondary cache corruption is a common CPU fault. The degree of light damage, or can be started, you can enter the normal desktop for normal operation, when running some I/O throughput of software (media playback, games, plane/3d drawing) will restart or panic.

Notebook computer automatic shutdown solution: Use the heat sink or fan to cool the computer, or clean the internal dust of the host, can also be shielded in the CMOS two-level cache (L2) or a level of cache (L1), or replace the CPU.
