Failure Phenomenon: G400 notebook, fault for the power of no display, replace the motherboard found that wireless can not be opened, the system is a Windows 8 system, method to install the Windows 7 version of power Management is not valid, the query BIOS version is up to date, install Windows 7 system normal. 　　Reason Analysis: Because wireless can be used with Windows 7 system, this failure should not be a hardware failure and may be related to t

1. Lenovo G400, G500 models, installation Win7 system and the official website of the EM Power Management software, the system frequently pop-up CPU occupancy Rate window as shown in Figure 1: 2. After the installation of power management, according to f11,f12 adjust brightness, the brightness order will occur, such as Figure 2, from the first level jump directly to the fourth level. Reason analysis: Caused by bug problems with earl

Lenovo G400, G500, G490 series models, F1-F12 function keys on the keyboard, by default is used as a specific hot key, as shown below:Press the hot key to quickly implement the corresponding function, as shown in the figure below:However, when using specific software or playing games, these buttons need to be frequently used. The FN combination method is too cumbersome each time. How can I change it to the traditional keyboard mode?Procedure:1. Press

to handle multiple incoming calls. Asterisk @ Home vs. Asterisk I have been searching for the two keywords Asterisk and Asterisk @ Home for a long time. The real difference between the two is that I have no clear and clear answer, however, from the information I have collected and mastered, the functions of AAH are exactly the same as those of Asterisk. The biggest difference between them is that the control and configuration methods are different. AAH can be configured and controlled through a

inbound calls can also be handled by completely different VOIP and/or telecom providers ). To connect to digital and analog phone devices, asterisk supports a range of hardware devices, most of which are manufactured by digium, a sponsor of Asterisk. Digium has one or four T1 and E1 interface cards that can be connected to the PRI line and channel pool. In addition, one to four simulated fxo and FXS cards
