MB number: Wistron LSZ-1 MB 13251-1 Problem: lenovo t550 only charges when it is turned off, connecting the power adapter to a laptop that is turned on does not give anything, the laptop does not show the charging icon. When the laptop is turned off, it charges without any problem.

It is possible to repair LCD? or just replace?

Okay, thanks for your help, problem is solved. I dont check LCD, it is broken.

Sorry, but i dont understand what i should do now. I checket, that 4 and 5 pin from u5202 is directly connected with 10th pin from LCD1 slot

Its 10th pin

My bad, power button not working good. U5202: 1-0.13V 2-0v 3-0v 4-3.3v 5-3.3v

I'm sure sir, on u5202 is no voltage on all of 5 pins

F 5201 - 19.6V on both side U 5202 - 0V on all legs

its 10th pin, not 11.

Pins 1-4: 19.6v Pin 11(?): 3.3v

okay
