Computer in the plug u disk is very afraid of static electricity. It has a great chance of damaging the device. Although its external interface supports hot Plug and certain protective electrostatic measures. The solution is to connect the power supply 220V grounding wire. The motherboard screw port in the computer chassis is not insulated gasket. Be careful not to add insulating pads to the top otherwise it may cause radiation interference and static electricity.
In addition, if you can not confirm whether there is static disk, we touch the U-disk before touching the grounding of the pipe, such as upper and lower water pipes, heating water pipes (do not touch the gas pipe) on the machine to operate as little as possible to wear chemical fiber material clothing, preferably wear cotton clothing. Do not be too dry indoors to maintain a certain humidity.
Sometimes because the host is not grounded, in the process of plug U disk will also carry static electricity, this situation will make the entire metal chassis will produce static electricity, quite dangerous, will also lead to computer crashes, encounter such a situation is recommended to cut off the computer power, to re-examine the electrical equipment everywhere.
U disk electrostatic problems, although not many, but once met is still quite dangerous, so we usually need to pay more attention, not afraid of 10,000 just in case, all the dangers are not easy to try, the above recommendations are also applicable to other computer hardware or precision electronic equipment.
