This morning to deal with the WIN7 system of the computer front microphone and headphone port can not be used, the main phenomenon is the headset after inserting no sound, wheat inserted into the microphone can not hear the speaker, the rear port all normal. At the beginning of the judgment is definitely set the problem, so with another computer Baidu search "Win7 computer front panel headset microphone can not be used", follow the steps, the specific content is as follows, open the Control pane
the conditional compilation Directives #ifdef Debug and #endif to wrap the printf functions together. This allows the debugging information to be viewed when the program is compiled with the-ddebug parameter, otherwise the debug information will not be displayed without the parameter.4.2 Debugging steps with GCC and gdb4.2.11, in order to be able to use the GDB debugger, in the compile phase with the-G parameter, program 2.3 as an example:[Email protected]:~/segfault$ gcc-g-o segfault3 segfault

From the above, GDB is no different from the usual debugging tools, basically complete these functions, but in detail, you will find GDB this debugging tool is powerful, you may be more accustomed to the graphical debugging tools, but sometimes, the command line debugging tools are not completed by the graphical tools. Let's see it all.

In the traditional power supply chassis, the power cooling fan absorbs the air in the chassis and discharges the computer chassis. In the power supply chassis, this suction channel directly points to the outside of the chassis, although the power supply fans can obtain cooler cold air, can direct the external dust inhalation is also unavoidable. In addition, the suction pathway through the bottom of the machine and the placement of the narrow gap between the surface, where the neg

Battery Endurance
In the case of continuous web browsing via Wi-Fi, Asus G750JX-DB71 has been on the verge of a 5-hour period, reaching 4 hours and 57 minutes. This result is not only far more than the average of 4 hours and 09 minutes, but also more than the Alienware 17 4 hours 10 minutes and the MSI GT70 4 hours 18 minutes long.
Software
Volans series of router products, in the power supply on the line is used to absorb high-pressure waves of the circuit design.
It has a large flow, capacitance small, residual low, fast response characteristics, so that equipment and lines and the Earth to form a conditional equipotential, will be due to lightning and the internal facilities to be induced by the lightning flow can be safely leaked into the ground;
will also be able to enter the lightning flow blocked outside.
