Hi guys ,
I have a little know how when it comes to this sort of thing , not a lot though. So here is the situation that I find my self in . Not sure how but my laptop died, when ever I plug the power in to the DC jack the blue light on the power lead turns off and you can smell a short coming from the jack. I have google around and so far all it indicates is that there is some sort of short on the board, I can not afford to buy a new board so my only option is to try and find the short and repair it. So far the things that I have found and done are :
0. I have tested with two different power leads and have checked the out put from them both, both are good.
1. I have removed the DC jack and plug that in to the power lead , blue light stays on.
2. I have used a different DC jack , blue light on power lead still turns off.
3. by passed the DC connector on the board and blue light on lead still turns off.
4. unabale to try the battery as that is flat, And I don't know of anyone that can charge it for me.
5. the only thing on the board that looked suss was cap PC102 it has lost the colour off the top and it feels like a small indent on the top. Its the only cap that looks in poor condition.
5. once the power lead blue light turns of it only gives 0.450 and that drops over time,
6. using the 0.450 from the power lead and the Schematic I was able to trace the 0.450 to PQ703 and that seems to not be getting the 0.450.
7. I have checked a few parts to see if the 0.450 is getting through and I have been able to pick it up in the following locations
PQ501
PQ502
PQ503
PQ504
PQ512
PQ507
PQ508
PQ502
PQ511
PL3
PL1
PQ704
PQ702
PC905
PC906
PQ701
PC915
PL702
PL701
So far this is all I have checked , any help that you could offer would be good , and any tips on what else I can try , I don't want to waste this laptop.
I have included photos and the Schematic for it.
