Hello,

 

By any chance, is Airplane Mode enabled on the ThinkPad P52?  If so, try disabling it and seeing if the ThinkPad P52 now charges while turned on.

Thinkpad P52 is charging only power off

A P52 might require a 170W charger to power the machine while started. What capacity chargers do you use?

Yes, I was using the original 170W Power  supply, after I replaced the other power supply, my laptop can boot up with normal mode.

you are right, after I replaced a charger laptop can boot up with new charger without battery in normal mode. but after I saw your reply I tried to change laptop mode back to Airplane Mode, the similar issue happened again, my laptop was no longer charging, then I remove the battery to boot it again, the laptop was suddenly died after login to windows 1-2 minutes. looks like there are something wrong with the Thinkpad p52 or windows 10 in Airplane Mode.

Airline seats cannot give enough power for P52. Hence In Airplane mode it is normal for the laptop not to charge.  What you describe is per design. Don't use airplane mode while connected to AC and expect the P52 to charge while in use.
