Hello Friends, Its case study of HP 15-bs542tu with MBD la-e791p which was having only 0.18A after power ON. The motherboard was cleaned and no sign of corrotion found on mbd. So after checking all the required voltage I found that EC_RSMRST# supply on pin 100 on KBC kb9022q was not present so I think to replace KBc so I remove KBC and found corrosion under KBC pin 100 and the track was cut due to corrotion. I make jumper and put the same KBC and ALL done. Supply on pin 100 also come 3.3v and Laptop is also OK. Everything works perfect.
