I use the computer is ASUS X550C, installed the ubuntu16.04 version.When connected, "WiFi has been disabled by hardware switch" is displayed. Press FN+F2 to not turn on WiFi. You cannot and cannot turn on WiFi via the Rfkill command.After understanding, you can suspend the notebook and then re-login, WiFi will be turned on, and every time the restart of the computer will need to suspend once, in order to use WiFi.Is there a way to do it once and for a

There are many ways to make a motion control system, you can use embedded system, Special Motion Control PLC, Industrial computer + motion control card, special CNC device and so on. PMAC control is generally used in Industrial computer + motion Control Card (IPC) way, so that there are more flexible building systems, strong scalability and other advantages. The following is a complete PMAC motion control System hardware composition and wiring and sig

Microsoft attaches great importance to the operating system of Windows 8, a few days before the burst will likely cause a hardware-level breach of the vulnerability. The security mechanism in Windows 8 can prevent attacks on the operating system and drive hackers to develop malware that can directly infect hardware. McAfee has mentioned this in its security forecasts for 2012. The advance of Windows 8 boot

Computer memory is a very important part of the computer, without a memory processor the computer will not function properly, so it can be easily understood that the processor communicates with other hardware on the motherboard by using memory as a bridge to communicate with other hardware, and the most important thing for a novice to see is memory brand, memory capacity and memory type. What is a d

The comparison between the Millet notebook and the Apple Air notebook hardware The comparison between the Millet notebook and the Apple Air notebook hardware How about a millet notebook? To do high-performance lightweight notebook. The millet notebook contrasts with the MacBook Air of Apple: Thin: 13% thinner than a MacBook Air. Light: Millet notebook only 1.28kg. Narrow: Ultra narrow Borde

Notebook crash, unable to start the system, the screen "freeze" no response, the mouse, keyboard can not input, the software operation abnormal interruption. Although the cause of the crash is manifold, but same, the reason can never be separated from the hardware and software two aspects. Poor heat dissipation displays, power supplies, and CPUs are very important in their work, so it is essential to maintain a good ventilation condition, if the moni

Hardware startup principle In the normal power of the ps-on is a high level, only when the ps-on is in the low electricity peacetime, it began to work. As shown above, in the normal time, Southbridge susc# should be high level, because this signal is low level effective, at this time the base of the transistor is low level, transistor cut-off, The 5V-SB is added directly to the ps-on to keep the power supply normal. Power failed to send a PG signal t

accelerator card. (4) Memory and hard disk Notebook interior also contains memory and hard disk hardware, where memory is connected to the CPU and other hardware bridge, determines a certain notebook performance, the current notebook standard memory has reached 4GB. The hard drive is the notebook data storage center, like the operating system, all kinds of files are stored in the hard dis

CPU and external devices, memory connection and data exchange need to be implemented through the interface device, the former is called I/O interface, and the latter is called the memory interface. Memory usually in the CPU synchronization control work, the interface circuit is relatively simple, and I/O equipment a wide variety of the corresponding interface circuit is also different, so, it is customary to refer to the interface is just the I/O interface. First, the concept of i/0 interface

Now buy a computer is more and more, and some buy assembly computer, and some people like to buy brand computers, some computer configuration is high, and some computer configuration is relatively low, regardless of configuration, the price of computers, we use computers should be good maintenance of computers, Here's what your computer hardware is all about: how to improve your computer's hardware and serv

Concept: The MAC address is the address used on the media access layer, also called the physical address, hardware address, or link address, which is cured in the adapter's ROM.The visible MAC address is actually the adapter address or adapter identifier. When a computer uses an adapter, the identifier on the adapter becomes the MAC address of the computer. The MAC address length is 6 bytes (48 bits) and is managed by the IEEE Registration management
