Books normal operation, a plug in the power adapter to shut down into the state of charge, and can no longer boot, but unplug the power, but also normal operation, why ah
Your adapter is not the original bar it is the case of the words If you then use the adapter must not be enough power to change it Well, do not use fake if the original too expensive to buy a good point of the brand such as Hunt Do not buy fake imitation is worth the candle
Phenomenon analysis: the current motherboard on the CPU temperature monitoring function, once the CPU temperature is too high, more than the motherboard BIOS set the temperature, the motherboard will automatically cut off the power to protect the relevant hardware. On the other hand, power management and virus software in the system can also cause this phenomenon to occur.
?? Should be the policy: the sudden shutdown of the phenomenon if it has been to confirm the CPU cooling is normal. Open the chassis visual fan blade is working properly, and then enter the BIOS option to see the fan speed and CPU operating temperature. Found that the fan is the problem, the fan on the relevant dust maintenance or replacement of better quality fan. If you exclude the reasons for the hardware, enter the system, from the "kiss to death" installation CD-ROM installed in the installation of power management, and then completely killing the virus. When these factors are excluded, the cause of the failure may be the power of aging or damage, which can be confirmed by replacing the power law, the power is broken on a new, must not continue to use, will burn the hardware
Two possible: First, the power adapter is broken, the other is the power interface is broken!
Go to the customer service to check it, the general computer testing room free bar, find out what the problem, do the next step.
good luck!
