hp 15 dar62cmb6a0 usb 3.0 not working
hi
i have hp 15 dar62cmb6a0 both usb 3.0 not worknig but usb 2.0 works fine
one usb3 port USBP0+ (D+) gives me short to the ground according to the schematic and boardview this lines goes directly to the PCH
other usb 3 port i have 5v and d+,d- 3.3v but not working
when i try usb keyboard all led in keyboard on but not working
is that means pch is defective
can i remove L37 and L36 of each usb 3.0 port and take d+d- lines from usb 2.0
without any risk ?
i notice D13 becomes very hot other side of the diod gives low amps reading 0.15amp...Last edited by mo000; 09-04-2023, 01:59 PM.

i need help with hp 840 g5 no display
hi everyone
hp 840 g5
computro 6050A2945601-MB-A01
this laptop comes to me with no display issue
sometimes only the led blinking with 0amps consumption
sometimes power on with 0.24amps consumption but black screen
i test every voltage needed and everything is ok except PVCCGT which is for GPU no short on output
the ic who generates this voltage has all requirement
this laptop comes from another repair shop and the try to flash the bios and i think they lost the original
i also try to flash new one but with no difference ....

from ram slot under the scope
sda on pin 200 =3.3v
scl on pin 202 = 3.3
dramrt on pin 30 = 1.5
i think i get the right reading ....
