Win10, what if this computer doesn't respond?If there is no response when you click "This computer" on Win10, you can refer to the following methods:
1. ** Reboot the computer **: The computer's resources may be occupied by other applications, causing the file explorer to not respond. Try to restart the computer and restart it.
2. ** Wait for a while **: If the computer's performance is poor or the hard drive is very large, the explorer may need some time to load a large number of files and folder. You can wait for a while to see if it will load.
3. ** Close the explorer and restart it using the task manager **: Press `Control + Shift + Esc`(or `Control + Alt + Delete`, and then select the task manager), find the "Windows explorer" in the task manager (it may be in the "processes" or "applications" tab), right-click it, and then select "end task". Next, click on the "file" menu, select "run new task", type "explorer. Exe" and press enter.
4. ** Check for viruses and malicious software **: Run an anti-virus software scan to check if the computer is infected by malicious software, because malicious software and viruses may affect the normal operation of the operating system.
5. ** Check hard disk error **: Hard disk error or file system problem may cause this situation. Open the command prompt (run as an administrator) and type "chkdsk /f /r". This will ask the system to run a check at the next scheduled restart. After the computer is restarted, the system will check and attempt to repair any hard disk errors.
6. ** Clean up unnecessary files **: If the hard disk space is insufficient, it may cause the file explorer to respond slowly. Clearing unnecessary files and the buffer regularly can improve performance.

The samsung a71 phone doesn't turn on, charging doesn't respondThe reason why the samsung phone could not be turned on and charged was probably caused by problems with the battery, charger, system software, hardware, and so on. You can try to shut down and restart. If the battery display returns to normal after refreshing, it will be fine. This can solve the problem of the wrong battery display due to system problems. If it can be charged normally after replacement, it means that there is a problem with the original charger. It is recommended to use the original charger and the data cable to connect to the power supply to charge. Do not use inferior counterfeit products. The battery's contact points may also be blocked by dust, which may cause the charger to misjudge that it is fully charged and not work. Use a cotton swab to clean the battery contact points and charge again. You can also take out the SIM card and the SD card at the same time, and then press the power button for more than 10 seconds to test whether it can be turned on. If the battery can be removed, try to replace the battery. This will help solve the problem of not being able to turn on normally due to system software or hardware problems.

The Rubik's cube doesn't respond to chargingThere were many reasons why the Rubik's Cube did not charge:
1. ** Low battery **: If the cube is not used for a long time, the battery will lose battery due to self-discharge. Even if it showed that there was battery, it might be a virtual battery. In this case, it might cause the charging to be non-responsive.
2. ** Aged battery **: The Rubik's Cube battery has a certain number of charges and discharges. When the number of charges and discharges approaches or exceeds the rated number, the battery performance will rapidly decline and it may not be able to charge normally.
3. ** Problem caused by over-discharge **: If the Rubik's Cube's battery is completely used up before storage, it may cause the battery to over-discharge, produce sulfur, and reduce the battery capacity, thus affecting the charging.
4. ** Charger problem **:
- ** Charger Malfunction **: Small components inside the charger may fall off or be damaged due to vibration and other reasons, resulting in failure to charge normally.
- [** Mismatched **: If you use a charger that doesn't match, you may not be able to charge the Rubik's Cube.]
If you encounter a situation where the Rubik's Cube doesn't respond to charging, you can try the following solutions:
1. For Rubik's cubes that may have a power loss, contact the after-sales service or follow the product instructions to activate the charging operation (if there is one).
2. If the battery is aging, you may need to replace the battery, but you must first confirm whether the product is under the guarantee period. If it has passed the guarantee period, you can solve it according to the after-sales solution, such as paying for the replacement.
3. Check if the charger is working properly. You can try to charge it on other devices. If the charger fails, you need to replace it.
4. Make sure you are using the original charger of the Rubik's Cube or a charger that meets the Rubik's Cube charging specifications.

The computer controller doesn't respond after a whileIf the computer controller did not respond after a while, you could investigate the problem from the following aspects:
1. ** Check hardware connection **: For the USB connected controller, check whether the USB port is clean and damaged. You can try to replace a different USB port or USB cable. If the controller is connected via Bluetooth, make sure that the Bluetooth function of the computer is turned on and the controller is in the pairing state.
2. ** Check power supply and battery **: If the controller is powered by a battery, make sure that the battery is fully charged. If the battery is insufficient, the controller may not work normally. If the controller is a portable controller, make sure that the controller is fully charged and connected to the computer correctly.
3. ** Check Driver **: The communication between the controller and the computer depends on the driver. You can check whether the controller has been correctly recognized and installed in the device manager. Most controllers would automatically install the driver after they were connected to the computer. If they were not automatically installed, you could download the latest driver from Driver Life and other software and manually install it. You could also check whether the controller needed to be updated with the corresponding software of the Beitong Game Hall for specific controllers (for example, the Beitong controller could be downloaded), or you could uninstall and re-install the controller driver.
4. ** Check game and system settings **: Check the settings of the controller in the game to ensure that the controller is correctly recognized and installed. At the same time, check the device manager in the computer system to ensure that the controller is correctly recognized and installed.
5. ** Operating system and game update **: Make sure that the operating system and game are the latest versions. Sometimes, system or game updates will fix problems related to the controller. You can update them by visiting the official website or using the automatic update function.
6. ** Try other computers or games **: If none of the above methods solve the problem, you can try to connect the controller to another computer or use the controller in another game to determine if the problem is related to a specific computer or game. If the controller worked normally on other computers or games, then the problem might be with the current computer or game.
