Yes. Fan stops. Backlight goes off. Image on screen disappears. Also light in USB mouse goes off.

Nope. R8178 = 3.3V PPVCC_S0_CPU = 0.8V

Hmmm. Actually not. It's apparently playing possum with me. I got power on S0 even when I use the Apple-menu to go sleep... WTF! I was thinking it was sleeping because the fan stopped. Motherf*****!! Please spank me next time I just assume instead of just measuring the fucking shit. Sorry man...

I did not but just tested without it for 5 hours. Battery charge went down from 100% to 74% with camera disconnected in the last 5 hours while sleeping.

It was on trackpad. Board connector was perfectly clean and shiny on all pins

New DC-in board, new IO cable, airport disconnected - still draining in sleep mode... Now what ? Thanks

Ok. It seems I must have remembered wrong when making the first test on losing charge while shut off... Because it is NOT as first stated. After double checking it appears that it is only losing power while sleeping. I checked all S4 and S3 while turned off anyways and no power on any of...

There is no L3895 on this one? Do you mean L3095. If so there is no voltage on it.

Yes. Also draining a little when turned off. Lost 10% in 5 hours.

I did not try that. I will try. Thanks

Thanks. Yes there was corrosion but as I wrote i changed both cable and trackpad. I'm pretty sure it goes to sleep. Fan stops but haven't measured any rails while sleeping

Hi. This one was liquid damaged, a small amount of rain water. Trackpad and IPD flex was a little corroded, did not turn on. Changed them and it started. Checked all logic board for corrosion under microscope, nothing to see. Now it is working but is loosing half of its charge over night in...

No luck. Same issue with new BIOS :-(

Thanks. I'll try to flash it and will get back with the result.

Hi This one works fine when only 2 GB RAM is used. But if I put 4 GB (or anything more than 2 GB) it is not booting. No beeps or anything just black screen and the DVD-drive "start-sound" looping over and over again until I shut it off. Working with 2x1 GB in each slot or 1x2 GB in either...

Customer: Hi, my computer says "no wifi hardware installed"...?? Apple "Genius": I'm sorry to hear that. It seems like we need to replace the main logic board. Customer: Oh, what's the price for that ? Apple "Genius": It depends on the amount of storage you got. :p

Looking like bad ram or ram socket

No but it measured a little bit low (48K). I switched it now measures 99K

It's a Fluke 125 Scopemeter (~2000 USD). Hmmmm. Normally I can measure SMC_RESET_L without problems

Thanks Duke. But with board out and keyboard connector removed it stills resets the smc when probing SMC_RESET_L. Why?
