iPad連接行動電源後沒有反應，實在令人困擾。 php小編蘋果對此進行了深入分析，整理出以下可能的原因：行動電源與iPad連接不當，請檢查連接線和介面。行動電源輸出電壓或電流不足，無法為iPad供電，請檢查行動電源規格。 iPad電池故障或充電介面損壞，請嘗試連接其他充電裝置。如排除上述問題後仍無反應，可能需要專業維修人員進一步檢測。
1：iPad自帶的充電器是分5.1V和2.1A二種的。
2：行動電源的USB介面輸出參數一般都是5V和500毫安。電流不達標或不匹配，所以iPad透過數據線接入行動電源時會顯示不在充電或連接沒有反應。
(但連接蘋果電腦可以，因為它的USB輸出電流達到了充電標準，這就是蘋果產品與蘋果產品之間的好處)。
1
檢查iPAD電源狀況，低電量會導致連線無反應，充滿電後再連接電腦。
2
測試USB連接線，以相同的線連接其他設備如手機測試，如USB線有問題，更換連接線。
3
電腦USB介面有問題，嘗試連接電腦主機後面的USB介面。
4
驅動程式出錯，重裝iTunes，可以解決驅動程式出錯問題，然後再連接。
5
使用iTunesWi-Fi同步連接，可以實現不用USB線直接用WIFI 連接電腦。
如果你的鍵盤連上電腦沒有反應，可能是以下幾個原因導致的：
1. USB介面故障：如果你的鍵盤使用USB介面連接電腦，可能是USB接口故障導致的。可以嘗試更換USB介面或使用其他USB設備測試該介面是否正常運作。
2. 鍵盤故障：鍵盤內部硬體或軟體可能故障，導致無法正常連接電腦。可以嘗試將鍵盤連接到其他電腦上，或嘗試使用其他鍵盤連接到同一台電腦上測試是否有問題。
3. 驅動程式問題：如果你的鍵盤需要安裝驅動程式才能正常運作，可能是驅動程式出現問題導致的。可以嘗試重新安裝鍵盤驅動程式或更新電腦的作業系統，以確保驅動程式正常運作。
4. 電源問題：如果你的鍵盤需要外部電源，可能是電源故障導致的。可以嘗試檢查鍵盤的電源線是否正常連接，或更換電源線和轉接器來測試問題是否已解決。
針對以上問題，可以嘗試以下方法來解決鍵盤無法連接電腦的問題：
1. 檢查連接：檢查鍵盤連接是否正確，重新插拔鍵盤連接線，確保連接穩固。
2. 更換USB接口：如果使用的是USB接口，可以嘗試更換其他USB接口，或者使用其他USB設備來測試該接口是否正常工作。
3. 檢查驅動程式：檢查鍵盤的驅動程式是否已安裝，如果沒有安裝，可以從鍵盤製造商的官方網站下載並安裝最新的驅動程式。
4. 更換鍵盤：如果以上方法都不起作用，可以嘗試更換鍵盤，或者將鍵盤連接到其他電腦上測試是否有問題。
需要注意的是，如果你不確定如何解決鍵盤無法連接電腦的問題，最好是尋求專業人員的幫助，以避免因不正確的操作而導致更多的問題。
如果你是新款的筆記型電腦，是有這個Type-C介面的，可以直接連接。如果是舊款的，就需要找一條以前的標準USB線。
It is not clear whether the two are connected wirelessly or wired. Different connection methods have different problem analysis directions. Assuming a wired connection, the reasons are as follows: 1. The data cable is plugged into the computer, and both are normal. The computer system will prompt that a certain device has been found, automatically install the driver and communicate with the device, and at the same time, the device icon will appear in the lower right corner of the desktop; 2. If the computer does not respond, it means that the connection between the two is not normal, the computer system cannot recognize the device, and naturally cannot be connected. Check whether there is a problem with the USB interface of the computer, or try another USB interface, or try another data cable. In short, the computer must recognize the iPad to solve the connection problem; 3. If there are some abnormal prompts or other abnormal phenomena, but normal communication cannot be achieved. At this time, restart the two separately and try to connect again. You can plug and unplug the data cable once in the middle. In most cases, the normal connection of the device will be completed; 4. Details. After plugging in the cable, carefully observe the performance on the iPad. If there is a charging indication, it means that the USB port function of the iPad is not turned on, the data channel in the data cable is blocked, and data cannot be transmitted. Go to settings and turn on the USB port function, and the connection will be successful.
First open your router and set the password and account to indicate that the network connection is open. At this time, open the iPad and select Settings, find the wireless connection, select Search to find your router, enter the account password, and click Connect. This You can now see the network on your iPad.
After the network connection is successful, a signal icon will appear on the iPad.
It is likely that the computer driver is missing or needs to be updated. After the iPad is plugged into the computer, the appropriate driver needs to be installed, otherwise the computer will not be able to recognize the device. In addition, it is also possible that the iPad's rechargeable battery is insufficient and cannot work properly on the computer. If the driver is installed and the battery is charging, but it's still not working, you need to check that the cables are intact and that the ports are clean. In addition to checking the above problems, you can also try to connect the iPad on different computers, which will help to eliminate problems with the computer itself and ensure that the device and computer can communicate normally. If these steps don't work, consider using an original service center to repair your iPad.
First check your connection cable, because the cable is the only medium to connect to the PC. If the data cable is damaged, there will be no good solution. In addition, if you can connect well one day but suddenly cannot recognize it the next day, the big problem may still be online.
Second point, think about whether you have disabled some startup items. If your computer has some assistant software installed, it will remind you to turn off some startup services, and these happen to be Apple devices. What is needed to start, such as opening an assistant, and you find that these two items are disabled, please open them quickly, and the problem will be solved immediately.
If a certain assistant is not installed, then we can find it in the service, specifically Control Panel - Management Tools - Services. If you see these two startup items, please start them quickly if they are banned.
Update or install drivers. It is possible that you uninstalled the driver of the Apple device due to negligence..

3. The signal in your location is not good and you cannot connect to QQ. You can change the location and connect again.
4. The above is a solution for data network connection, but if you are connected to a wireless network, you need to check whether the iPad Wifi password input and the Internet settings of the wireless router are correct, and whether other devices can access the Internet through WiFi. It is recommended to delete the iPad's WiFi password and re-enter it, or restart or reset the wireless router.
