In general mobile hard disk normal access to the computer, my computer or computer disk management can see the symbol of the new hard disk, the most simple and direct into my computer can see the new mobile hard disk symbol, she did not see can wait refresh to see under my computer, my computer management View.

① When encountered removable hard disk does not show we first check whether the mobile hard disk data cable connected to the computer and mobile hard disk no, sometimes not plugged in, the computer does not recognize the mobile hard disk more, another mobile hard disk USB connection good, we look to the host USB to accept whether adverse, a change in the interface to try, the front will not do, for the back and try again. Computer crash? Computers often crash how to do?

PS: Some computer front USB interface did not connect to the motherboard interface, leading to the front USB interface can not be used a lot, so this also needs attention.

②Ensure that the host computer USB interface is available, and the 50Ft SVGA VGA Monitor M M Male To Male Extension Cable and hardware connections are secure, mobile hard disk is still unable to show we can try to re unplug host US interfaces, wait insertion to try again, I encountered this The case began to access the computer prompts due to equipment access, but not see the mobile hard disk drive letter in my computer, but repeatedly re-plug a few results there.

③ First up to try to get another computer, if normal, is the matter of your system, if not normal, that is, your hard disk or hard drive USB cable. Find a good USB cable to try it first, or not work is the hard disk, repair, and general hard disk will not repair.

Own system from the Device Manager to see whether the abnormal icon in front of the mobile hard disk, such as the question mark exclamation point, you add new hardware, re-find, and check under the computer services whether banned service, it can not and do not know where the problem friend can restore the system to normal (eg: a key to restore or reinstall the system), and then connected to the test, most problems can be solved. There are problems ... the last time to see the BIOS settings or the BIOS back to factory settings, does not work, check your motherboard.

Two situations:

1) the computer's USB port itself is not a high-speed interface, and removable hard disk for high-speed hard disk, so even energized normal can display mobile hard disk; You can view the computer's USB port, general computers have several USB interface, if the pre-effect bad, as much as possible to use set USB, and is best connected to the USB interface on the mobile hard match. Tip the print spooler service is not running "solution!

2) mobile hard disk on the power supply requirements, if the computer's USB port is insufficient power supply mobile hard disk as lights, there will be speed, but to take power, and can not operate normally, of course, will not be displayed on the computer mobile hard disk drive letter.

Of course, the above is to ensure that mobile hard drive is good, if it is unable to determine whether the removable disk available notebook trial, because the notebook to a removable disk power supply is powered double-headed disk data by moving the line, in general, the mobile hard disk suddenly recognize the disk, there are several possibilities. First, check the USB interface, for the trial of a USB interface, if conditions change a computer test, to remind here, try to set the USB interface connected to the computer after, because the chassis front USB interface possible voltage instability. Secondly, removable disk cartridge, reinstall or replace a removable disk cartridge and data lines to try; Finally, if you exclude the above problems, there may be the fault of the disc body, should stop the energized try, if the hard drive is still in warranty went Warranty . Over the warranty period, and the data is not important, you can use the MHDD detect bad sectors, but to do the operation from the disk, in DOS, swept out of the red and green blocks, MHDD also comes with a repair function, you can try to use mobile hard disk repair tools for mobile hard disk repair, repaired recommended after this hard drive is not recommended to save important data, because this hard drive may have been faster problem can not guarantee that data can save long lost important data more harm than good.

We use the vast majority of mobile hard disk and U disk are using a USB interface is a plug-and-play type. We often use the USB device also may encounter a situation that does not recognize the mobile device, that can not find the drive letter of the USB device.

1) just power, high voltage charging sound, while the power indicator is green, after about 5-10 seconds after the light turns orange, and accompanied by the loss of hypertension creak La La "sound. At this time probably can be judged that the display 15-pin USB data cable line or field sync signal line (13 or 14-pin) have a disconnection of a display mistakenly believe that the host does not have sent the signal, after 4-5 seconds automatically enter a low energy state.

2) power high-voltage charge of the sound, even if you remove the signal line, power indicator light is always green. This situation is generally the line scan circuit failure, did not produce high voltage.

3) when power is high voltage charge of the sound, no image on the screen, remove the signal line, the power indicator for a while turn to orange, accompanied by the sound of high-voltage discharge. This case to the circuit failure, the general is not coupled with an operating voltage of the CRT, then you can look at the CRT filament is lit. Is also possible that the gate voltage is not coupled.

Now connect the notebook LCD TV of the more common interface has the following three types: VGA, DVI and HDMI. DVI and HDMI are both digital transmission, in order to better ensure the picture quality. HDMI can also transfer audio, without the other speakers,USB PS2 - PS3 Game Controller Adapter HDMI Cable or optical fiber connections more convenient.

Thus the whole, the first HDMI interface, followed by the DVI interface, and finally the VGA interface. First you should make sure the LCD TV video input, only VGA interface, then any a laptop capable of; If you have a DVI or HDMI interface, then buy a notebook, we should pay attention to pick!

Finally, if you would like to use the optical output audio signal, then we should pay attention to the selection of a notebook with Spdif optical output. (DVI and HDMI conversion, system conversion after only transmit video signals can not transmit an audio signal.)

Also note that the first set the TV to VGA input, and then set the display resolution TV to the second set extend the desktop to the monitor, a combination of keys on a laptop, usually Fn + a similar display pattern button, you can switch to the VGA output. Since the TV has a VGA port, it means you can use when the display, I think you should check your TV standard is PAL, or NTSC, change to try?

LCD TV now mostly with HDMI, the CRT, color and other video input interface, using the HDMI is connected to the computer and LCD TVs is the easiest and most convenient way. Notebook is equipped with HDMI interface is not a lot, so you must first look at whether your laptop has a HDMI interface. If so, you only need to buy a good quality 2X Premium 50Ft 15M HDMI Cable PS3 HDTV 1080P Adapter, you can use the LCD TV to play the video in notebook computers. Should be noted that most of the LCD TV can support 19,201,080 resolution, but the vast majority of notebook computers are unable to support such a high resolution, and connect my laptop and LCD TVs, you will need on a laptop settings.

As follows:

One in the desktop, right click on Properties

(2) to enter the Display Properties

Then select the Settings tab

Choose your LCD TV models in the display device, and select the appropriate resolution for the LCD TV, for example, 1,280,720 or 19,201,080 at the same time check the Extend my Windows desktop to the display options in order to allow LCD TV Buzhi Yu image distortion in the display of the contents of the notebook computer

In addition, in order to transfer the laptop audio to the LCD TV, then you also need in the Device Manager activate HDMIAudio equipment in order to achieve Pictures HDMI transmission.

If your laptop does not have a HDMI interface, then you have two lines of the traditional CRT 2 HDMI 10Ft Gold Cable HDMI F/F Adapter For 1080P HDTV and AUX audio line to connect the notebook and LCD TVs. These interfaces are also very good looking notebook blue 15 D-type interface of the pinhole is the CRT output interface, LCD TV will have the same interface, the two special wire to connect to; audio use two 3.5 mm standard audio transmission line can be. HDMI settings, video settings, audio, select the Device Manager inside the ordinary sound card, no need to specifically activate HDMI sound card.

What is the smart community cable

Cable choice is one of the vital link in the construction of the digital cell. Taken several options: 1, twisted pair;, coaxial cable;, fiber. From the practical point of view, twisted pair, due to price factors than the latter two cable has an advantage, but because it should not be used in the video needs, in addition to the theoretical length of not more than 100 m (transmit data), so after two 10Ft 10Ft 15Pin Monitor VGA SVGA M/M Cable 3.5mm Audio worth considering. Here I will list the advantages, disadvantages and applications of the three cables.

UTP

Can be used to transmit analog, digital signal, its broadband up to 268KHz, the digital signal, the baseband signal to send, up to several Mbps, such as T1 line data transfer rate up to 1.544Mbps, and can achieve 15km data transfer (an increase of the repeater), but not suitable for transmitting high-frequency data, such as video. Applicable to the choice of the point-to-point and multipoint.

Coaxial cable

Can be used to transmit video and data signals. Transmit analog signals, the frequency can reach 300-400MHz. High-speed data transfer rate can reach 50Mbps. The typical range of data transmission within 1km 10Mbps (tens of kilometers of transmission, but need to add a repeater). Its more expensive than UTP, but the number of devices may be limited to about 20-30 units. Suitable for transmission of video, data, etc., suitable for point to point, point-to-multipoint connection.

Optical fiber

Not only can be used to transmit analog and digital signals, but does not meet the needs of video transmission. Its data transfer rate up to thousands of Mbps. If you do not use the repeater, the transmission range can reach 6-8km.

Looking at the development of the wiring system at home and abroad in recent years, we can see three stages: a UTP stage. At this stage, the voice with the large-scale data communications can not be mixed to adapt to the data communication. 2 coaxial + twisted-pair stage. It can meet the user's data transmission and video needs, but need more access devices, the cost relative to many, and difficult future expansion needs. 3, the fiber stage. The final stage of what we call, at this point, the corresponding ancillary equipment better, the data processing power, and better scalability. In recent years, the development of fast, the price of access equipment is subject to adjustment, we can say that this step integrated communication stage.
