According to recent user feedback data analysis, about 65% of charging problems can be solved through basic troubleshooting. If you still can't solve the problem after trying the above methods, it is recommended to bring your proof of purchase to the official after-sales outlet for testing to avoid disassembling the machine yourself and voiding the warranty.
Warm reminder: Some new tablets support wireless charging. If wired charging is abnormal, you can try using a compatible wireless charger as a temporary solution. However, it should be noted that wireless charging efficiency is usually lower than wired methods and is more suitable for recharging power at night.
