Hello everyone!!!,
I hope in dedicated topic,
I'm in the process of opening my own electronics repair store, and I need your help with a list of must-have components like ic, mosfet, smd diode resistor etc... for PC repair. and purchasing links will also be useful. thank everyone!

pr57 = OL on 600k calibre
pr3264 = OL
so what can be cause these resistor defected it's my first time to face thes issue on laptop motherboard, verry glade to learn more.
i don't know resistor part size to order it's verry smal. how can find size?
there is way to force enable pin with wire jumping?
thanks for our support...Leave a comment:

OK I will do it tomorrow thanksLeave a comment:

Measurement on PIN 1 of [B]PR57 [/B]is not constant with a caliber of 600 Mohm it start at 4.12Mohm and decreases
on [B]PIN 2 of PR57 is [/B]constant = [B]143 kohm.[/B]
resistance from the left side of pr57 to the enable pin on the regulator is not also constant with caliber set to [B]600K [/B]start[B] 121k[/B] andincrease
enable [B]PIN 11 [/B]to ground is [B]102K[/B]Measurement on PIN 1 of [B]PR57 [/B]is not constant with a caliber of 600 Mohm it start at 4.12Mohm and decreases

Thanks for reply
resistance to ground on pc43 (+3VS5) = 15,5 K
resistance to ground on pc43 (+5VS5) = 64 k
+3VPCU= 33k
+5VPCU=175k
Voltage to ground enable pin;
PIN 11 EN2 (PU10) = 0V
PIN 11 EN2 (PU11) = 0V

Alienware 17R2 dead, no power, no charging
Hello everyone,
I just received an Alienware for repair, the pc seems to have been tweaked before.
I did an inspection and some components are missing. the pc does not turn on, after the tests on the main rack I have the 19v from the charger to the drain of the pq707 and to the pq701and :
PQ707 : Source= 17,46V ; Gate=19,52V ; Drain= 19,52V
PQ701 : Source= 17,46V ; Gate=19,52V ; Drain= 19,52V
PQ702 : Source= 17,46V ; Gate=14,18V ; Drain= 16,96V
PR702:16,96
I don't understand why the voltage at the main line is 16.96.
Is it because missing...
