HP Spectre x360 convertible no power

[Tend0]

Hi everyone I have an hp Spectre 13-aeO89nz with no power du the battery issue battery was burn
In the motherboard we can see burn MOSFET and I have short to ground
In the picture the different values of resistance to the ground
Burnt remove MOSFET resistance value gate -source : 5.175kohm gate-drain: 0ohm , source-drain : 0ohm
When I plug charger I have 15v 0A no current
I have short to ground in the battery connector Remove MOSFET on source pin
My question is how to find faulty components?
Thanks for us 😊
Motherboard is DA0X33MBAF0 Rev:F

Measure the coils again in 200 Ohms range. KiloOhms is to high to guess something but it already looks like you have at least to power rails short to GND. Probably bad news but we'll see.

I am using the UT890C unit-t and the minimum range is 600ohm so I took all the measurements in the 600ohm range and these are the values I get

This is with red probe to the coil and black probe to GND? Seriously either with Yourmultimeter or with your measurements is something very wrong, or you can bin the board immediately since it isn't worth to continue with so many shorts.

You even missed the coil near the CPU this time and I'm also interested whether there are more coil on the other side of the board.

Re: HP Spectre x360 convertible no power

hello thank you for your help.
Yes sir red probe to coil and black probe to GND
I recheck the measurements with the black probe on the GND and the red probe on each coil and vice versa I still get the same results as before may be to try another multimeter
Other side there are 4 coil

Okay, one after another. In the first picture some coils were at KiloOhms while at the second pics the same coils measure 0 Ohms. Please check the manual of your multimeter or share pictures of the display to rule out whether your Multimeter shows "O.L.", so Open line, instead of a short.
