A1502 820-3476 No S4 - I'm lost

[Tony Tone]

How come I don't get anything on U7501 pin 2 on a good working board? Am I doing something wrong? I'm seeing the same shit on a working board. Am I suppose to short this thing on before I test? Probably why I can't fix shit?

 

[Tony Tone]

Plus I get no fan spin or nothing on this good board too. WTF !? Is this 45W MagSafe the fucking problem???

 

[Tony Tone]

But I can use this same fucking plug and it will work when fully assembled. But now that it is broke down and comparing measurements from this good board it's giving me the same shit.

 

[XooP]

You have to use at least a 60W charger. You can use 45W but only when battery is connected.

 

[larossmann]

use an 85w adapter for everything. it is worth buying this from apple.com just to ensure you're troubleshooting with something that will work

 

[Tony Tone]

Ooooohhhhhh...... Thank you !!!!!!!!!!!!!!!!!!!!! I never knew this !!!!!!!!!!!! Probably why i've never fixed a board to date... Lol !!!!!!!!!!!!!!

 

[Tony Tone]

Yes sir.... Thank you !!!!

 

[XooP]

Yes, to have one that works on everything, you should get an 85W MagSafe 1 and a MagSafe 2 converter for the newer boards

 

[Tony Tone]

Yes!!!!!!!!!!!! Got 5v on pin 2 now !!!!!!!!!!!!!!!!!!!! Hahahahahahahahaha
thank you !!!!!!!!!!!!!!!!!!!!!

Guess I can give Apple back their $85 I've been stealing from them. Overheard a Genius there helping a customer said she has a hardware issue because her phone don't charge. Sold her a new one for $399. Sad shit. Shit should be illegal. People should class-action their ass. $3 would of fixed it.

So then U0500 got a little warm now. Got S4's, S3's & no S0's. Will investigate. Been stuck FOREVER on the S4.
: )

[larossmann]

The CPU can't get warm with no S0. Something funny is happening here.

 

[Tony Tone]

No Title

 

[Tony Tone]

Does this mean I fixed it?

 

[Tony Tone]

CPU hotter than fish grease. This means its going to die?
Do I have to replace it?

Based on some more videos I'm watching (learning as I go), it is possible that something else is possibly causing the CPU to get hot?
I'll see if I can find out and maybe rewash this mug. But it is turning on & working : )
(small victory)

 

[Tony Tone]

Think its just me. You need to short it on in order to get the S0's running correct? Think I wasn't doing that before.
I was doing the monkey see monkey do on the U1950 (I think it was), but undid it.

 

[larossmann]

All macbooks cook, it's why they die all the time. What temps are you getting at idle, vs let's say watching a YT video?

 

[Tony Tone]

I don't know about temps. I only have the bare board plugged in and it is super duper fucking piping molten lava hot. When I had hooked-up to test if it worked the rest of the computer is fucked off (keyboard, battery, mouse, etc. The other 1502 I have is different and don't look like it belongs LOL, so no clue on the YT test & idle). Or, do you think its OK? LOL! Going through your videos for insight hu,hu.
I'mna try to find out about those temps.

 

[Tony Tone]

Got a "Go Directly To Jail" card. Nothing on the screen now and I got temps of 140 with no battery and 184 with the battery after about 1 min.

(Actually, I think the drive was bad. With no drive I'm getting the question mark folder. I think there is no back light, I'mna try to fix dat ; )

So it may be ok with temps like that? Throw on some ArticSilver and call it a day?

All & all I'm surprised to have made it this far. (clap)(clap)(clap)(clap)
