Still stuck on this one, any hints on how to revitalise PM_SLP_S4_L?

And off course, so are you Dukefawks :) Thank you both so much, another success...

Louis was totally right, replaced U2800 and the fan spins, that means that the computer is totally fine :) doesn't it?

Did some measuring and I also have 0v on the output of Q3880, shouldn't there be 12,56v here?

[solved] 820-2936 fan spins for one second then stops then starts then stops {CLOCK ISSUE} Got this liquid damaged 820-2936 board. There where corrosion on both sides of the board around U3890. R3888 was blown and I have replaced it. I have also replaced all the large caps above U3890 since...

Yes it's missing, I wrote that in the first post

Then the board is clean, sorry to say still nothing. I have now measured the resistors R1300-R1304 and there are 3.3V on all except from R1301 pin 2 which is 3.0V. When I measure PCH_CLK32K_RTCX1 i get 0.4V, I don't have an oscilloscope right now.

Ok, thank you, love the experience level on this forum...

Ok, is it then possible to swap the isight/wifi cable to fit if using a different assembly. The Bezel is fairly easy to take off.

I'm just talking about the panels, not the entire assembly, glad to hear their the same :)

Does anybody know?

Ok, I'll try :)

No ultrasonic yet, the board shows litte damage/corrosion but there are som dried wine on the middle upper part of the board. I'll check the resistors when I get back.

Got this board today, trying to figure out whats wrong with it. I have gone through all the S5 rails and their all present. The board is completely dead and PM_SLP_S5_L, PM_SLP_S4_L and PM_SLP_S3_L are all missing. ​I'm assuming this is because the PCH is not getting power, but what powers the...

What do you mean Louis? How I got it off with a knife or if I got it to work? Well, it works now :)

Got one of another board, used an exacto knife instead of heat :)

Ok, Ill try to remove from a donor board, thank you

I need the other end to be soldered to the motherboard.

Got a 820-3115 today that would not charge or run of the battery. The board was water damaged around the battery-indicator connector. Removed the connector and replaced the components around. The board now runs fine and the battery is charging. My problem now is, where do I get hold of a new...

If you are going to use a battery to find the short you must make sure that the resistance on the circuit is more than 0.2 ohms which is about the inner resistance of an alkaline battery. If the circuit is less than 0.2 ohms all the heat will be inside the battery.
