Re: Hp Pavilion 15, MB DAO092 no power help pls.
Hi tibd,
Thanks for the quick reply, i did diode mode source gate, gate source load check PQ21 it seems ok if i am not doing something wrong.
19V comes all the way to charging IC PU2 pin 20 (pg no 28). pin 2 and 4 0.2 V and switching to 0.1V pin 18 0.4 V HIDRV. 2.8V on the pin 6. No 5V coming out.
Any suggestions?
Cheers...
