Default Re: HP 15-dk LA-H462P - 5 long 3 short caps blinks.

Alright took me a minute to get all the measurements on the pic, but this is what I am looking at now.

It appears to me that the path of voltage ends at the ON Semi NCP81253MNTBG where it should be providing DRVH/DRVL (Driver High/Driver Low?) to the EMB09A03HP N-Channel MOSFET which would then feed VCCSA to the coil? Or am I totally misunderstanding how the circuit works?

At this point, the ON Semi NCP81253MNTBG looks like the culprit to me, but you guys know more about this stuff than I do. Any thoughts?
