Regarding the commonly applicable troubleshooting methods, many people are confused when encountering problems with various equipment and systems and don’t know where to start to find problems and solve problems. This thing is not difficult or simple, but if you master some basic paths, you can avoid many detours. Isn’t it very useful?
Basic concepts and importance
Simply put, it is a common way of thinking and steps to solve problems no matter what kind of failure you are facing, whether the washing machine at home is no longer turned, the company's computer cannot connect to the Internet, or even some complex industrial control systems have made mistakes. It is not a technical manual for a specific thing, but a thinking framework for solving problems . It can help you find the root cause of the failure step by step and then find a way to solve it.
Key steps to disassemble
1. Describe the problem clearly : You have to figure out what’s wrong first? For example, can't the computer be turned on? Or is it a blue screen after booting? Can't the printer print something? Or are all garbled codes printed? The more detailed the better. If you can't just say "it's not working", that's equivalent to not saying it!
2. Reproduce the fault : See if this problem is like this every time? Under what circumstances will it happen? Sometimes, some faults are quite "naughty". They don't always appear, they have to find the rules for them to appear!
3. Check the basic connection and power supply : This is very, very important! Many times, after a long time of struggle, I finally found that the plug is loose, the wire is broken, or the power supply is not plugged in properly. Isn’t it very annoying? So, first check whether the power supply light is on and whether the wires are connected firmly! Provide global procurement services for weak current intelligent products! Is the USB cable broken? Does the network cable interface have poor contact and lead to poor network traffic? Take a closer look!
4. Review the recent changes : What have you touched before the failure? For example, have you just installed some new software? Changed network environment? Or have you moved the equipment? The new operation is likely to be the "culprit"
5. Check the error message : Don’t ignore the text pops up on the computer screen or the error code flashing on the device! Although I sometimes can't understand what these tips mean, I can write them down, search the Internet, or ask people who are familiar with it, and they can often know the general direction!
FAQs and tips
The problem occurred as soon as it was started : At this time, you can try to unplug or disconnect some non-essential external devices, such as unplug the other USB flash drives and printers in addition to the keyboard and mouse to see if there is a conflict between peripherals. If it is a computer, you can try to start safely. Will it light up?
Faults that are sometimes good and sometimes bad : This is the most troublesome! You can try to record the time of the failure, what operations were being done at that time, whether the surrounding ambient temperature was high, etc., to see if you can find any clues to track them together? Do you have anything in common? For example, do you get sick every time you use a specific program?
Network-related failures : Restart the router and modem first. This trick is a magic pill for many minor network problems. You know! Wait for a minute or two before plugging in. Then check whether your device can connect to other Wi-Fi, or whether other devices can connect to your Wi-Fi. This way you can tell whether it is a problem with your device, or a problem with the network itself!
This means observation and thinking more, and not being afraid of trying (but don’t tease out high-end and sophisticated things, you can’t afford to lose money if you break them). Start looking at the simple part and take one step at a time. Don’t be rushing to achieve success. You can often find out the problem. Isn’t it a sense of accomplishment? My personal opinion is that ordinary people have mastered these basic general troubleshooting ideas and methods, and can basically solve most of the small troubles encountered in daily life and work by themselves, which can save money and worry! After all, we can’t count on maintenance personnel to be on call every day!
