Use environments, such as industrial PC in factory workshop, a boot without showing?

Industrial computer in fact is the industrial production of the electronic computer is also called industrial computer, namely however is on a computer, in the use of a long time will will fail, is very natural environments, such as industrial PC in factory workshop, a common fault is very normal, just below the industrial PC in the natural environment such as workshop start no display the status of the information to do a simple detail. The removal of the common faults way start no display information. （ No alarm) Step one: the first to check the wiring of the industrial control is connected and the plug each wire again again, the common fault is cleared. Step 2: if the common failures are still, and then open the computer main box query main box with no unnecessary internal metal, or computer motherboard deformation caused by short circuit fault, smell the main box there is no burning smell, computer motherboard have damaged integrated IC, capacitor have destroyed surrounding the CPU, etc. Step 3: if not, then clear the dust on the computer motherboard, then check the computers are all normal. Step 4: if the common failures still, then pull out the computer motherboard Reset line and the power switch, indicator light on-line, then used the self-contained power switch short-circuit fault silk knife, can look to start. Step 5: after the above process still can't open the machine under the condition of the dial to computer memory chips. （ According to the computer memory chips, and gently on either side of the lock. Computer memory chips will itself out) Not inserted memory under the condition of start, see whether the device will have the alarm sound for a long time. （ General industrial control computer motherboard is not running memory warning sound design) If you have, is a computer memory chips have dust above can be confirmed. Can use rubber scrub red gold finger area will run again memory back. If there were no rubber, can be used to carry RMB brush try. Step 6: if do not receive running under the condition of memory or no sound, and then use method of power supply circuit, the computer hard disk, floppy disk, cd-rom phone charging line pull out, then if inspection on the computer can start, if appear on monitor screen of a computer animation, suggests that fault here a lot of machinery and equipment. Then each connect the above several machines on a computer, when connected to one of machinery and equipment, common failures, suggests that common faults are thus caused by machinery and equipment, the final key to check the machine equipment. Step 7: when the power circuit method or not can be started, the BIOS can be charging and discharging. Some computer motherboard BIOS in machinery and equipment in the column of VGA and DVI display information or VGA and HDMI output, after this option was selected to display information to the DVI or HDMI output will display systems, if did not meet this kind of machinery and equipment will appear the status of the screen no display information. This kind of situation can clear the computer motherboard COMS after repair system recovery. Computer main board with a jumper cap COMS. Really can't find it to remove the computer motherboard that rechargeable batteries, such as a 4 to 5 seconds after it put on again, then start to try. Step 8: if all normal boot, equipment will be a short, after hearing they can press the Numlock function keys on the keyboard, can press continuously, if the keyboard display lamp can be bright, confirmed that the equipment is already open. Back into the system of this kind of failure can be according to the common system software failure to deal with. Industrial computer is actually on the computer, just because the computer motherboard circuit principle, to the outside world anti dust, waterproof, and its seismic demands more targeted. Natural, since is the electronics product, unavoidable appear in the application of various conditions lead to equipment can't open. Can refer to the general solution to deal with commercial notebook, above the key for the natural environment such as industrial PC in factory workshop start no display information under the conditions of solutions are obtained.
