1、 The sound of the fan on the touch touch screen kiosk is too loud
Problem analysis:
1. temperature control fan, when it is turned on, the sound will be bigger than usual;
2. fan failure
Solution:
1. When dealing with the problem of loud sound of CPU fan, if the user indicates that it was normal before, this situation can be shown to the user: affected by the use environment, all parts of the machine will inevitably be stained with dust with the increase of service time, and the CPU fan is more obvious. When the fan is started, the fan will run at full speed, so the sound of CPU fan will gradually increase with the increase of service time, which is normal.
2. If the sound of CPU fan is always relatively large during the use process, it is suggested to remove dust, add lubricating oil and replace CPU fan for CPU fan. These operations have high requirements on user operation capability. At this time, it is recommended that the user send it to the maintenance professional for operation.
3. The use of PC-specific lubricants is required to add lubricating oil.
2、 After the touch screen kiosk is used for a period of time, the screen displays no signal.
Problem analysis:
1. wires loosen or poor connection;
2. hardware failure; The display prompts no signal, and the possibility of display failure is not very high
Solution:
1. it is recommended to check whether the signal wires of the display and the PC mainboard are loose;
2. If you have certain operation ability, you can open the shell, plug in and plug the graphics card and memory to test again;
3. the above method is invalid, considering hardware failure.
