My cyberpower p151hm1 gamming laptop suddenly got shut down while I was working on it. I felt a burning smell around. No more powering up.
I opened the board to see the burned out component. I noticed that smell was coming of the Inductor shown in this pic:

Checked 32 pin Charging Ic (MB39A132) . Vcc was there, but 3V and 5v was not appearing on its output. I replaced it with another Ic of the same with no success. ( the charging Ic is shown here in this pic (1).

The 8 pic Dual N channel FET (NIKOS PD1503) shown in (2) is getting extremely hot. Didn't found its replacement..
No idea what to do.
Anyone can help please!
will be highly appreciated.
Thank U.

I will try to help you, it will take some time to diagnose and maybe find the problem. By the way, did you change the PU10 chip, if you did, you did a good job to solder that chip. Ok, let's start, give me all the voltages you have on this chip (charging chip), pins 1 to 32, be careful to not make a short.
