help : hp 14 m/b : DAR62CMB6A0

[bigbily09]

i have a hp 14 laptop
m/b : DAR62CMB6A0

The problem was with power but display on screen.
i tried bios reprogram first but still no luck , and as far as i troubleshoot the motherboard. i check the coils 3.3.v is present but the 5v is not. so i download a diagram. then i see that the ic controls the 5v 3v is pu10 and pu9 . after testing some pins of pu10 i see that the 5v ic is only outputting 2v and the pu10 is heating much.
after that replace pu10 and pu9 but still no luck. still ic is heating

please help

heres the diagram i use

Re: help : hp 14

check small capacitors near kbd connector. Mostly it goes bad in this particular mobo and its connected to 5v line. Very likely this will resolve your problem as i have got exact problem in atleast 3-4 R62 mb.

I dont remember the capacitor number, If you cant find out i can give you the exact number but tomorrow.

Try and update about results,if any
