I use English. Currently I use a power supply, not an adapter, so it doesn't recognize the charger. Newspaper must use 65W charger

DELL Use the One wire protocol to communicate with the charger, after reading the data from charger mid-pin and verifying the CRC, it could be examined to find the field that specifies voltage and current.
Charger with damage or no mid-pin may still power on the laptop, but display a warning message and not charging the battery.
You can get a female 5.5 x 2.5 to male dell 7.5 x 5.0 charger adapter DC jack from an online store to send fake data to the laptop pretending DELL charger.

This should work, and Dell has two kinds of power heads, big mouth with needle, small mouth with needle. The power head has a built-in chip, which can simulate the original adapter and has the function of charging. You should be able to buy it on Taobao.

连蒙带猜,估计意思像是他直接用可调电源连入充电口的正负极来开机,但开机后有他图上的错误信息,问有什么解决方案。

客户没有电源吗,直接换个电源就好了呀,如果自己拿来测试可以用转接头
