Hi
I have this laptop
MB: B5W11 LA-E061P
When put dc power on first FET has 19v on pin-5 but after that on +19v_P1 has 0.9v only (fet not switched on) also on main power rail only 0.9V
With battery main power rail is ok, 16V and laptop starts ok
If I short drain-source on first FET then I have 19v on main rail, battery charged but FETs for charging goes very hot
Any help?
Thanks
P.S. Just to mention that not have LDO on 3/5alw becouse no voltage IN-19v on drivers ICs, only 0.9v...
