      Hi. I have a problem with a HP probook 650 G1. 3 months ago it stops charghing the battery and the pc works just on battery. It seams the power that come from the dc input does not reach the board. I disassemble it, make a clear cmos but nothing changed. I leave the board disconnected for about 1 hour and then the pc started to work properly. Now I have the same issue but I don’t know ho to fix it. I shere some pics of the board.
      Here the mesures of the 4 mosfet I numbered on the pics.
      Here the mesures
      1
      S-D 52 kOHM UP TO 0L
      S-G 208 KOHM
      G-D 1,2 MOHM
      2
      S-D 30 kOHM UP TO 1 MOHM
      S-G 202 KOHM
      G-D 146 KOHM
      3
      S-D 20 kOHM UP TO 20 MOHM
      S-G 3,8 MOHM
      G-D 510 MOHM
      4
      S-D 1,5 MOHM
      S-G 2 MOHM
      G-D 270 KOHM
      The mesures seems to be good, isn’t it? No low resistance
