hi! i've received a a1466 completely dead.

i've found water around u6101 and u1900

removed ics cleaned and soldered two other ic from donor board! all ok!


today i 've received again this laptop...dead...again

i've used some solder and flux on u6101 and again live!

BUT...

it is extremely slow i have to wait like 30 secondo to hear the sound and 10 second to see the logo since i push the power button

then system bar start to load but OS seems impossible to charge...

if i use another ssd, it boot faster...and i can use the laptop without problem.

only problem is that cpu seems extremely hot even if i have changed the thermal paste

now i have tried to format the original ssd...but it is loading catalina from usb since like an hour!!!!


diagnostic test doesn't find anything...only "poor battery performance"

Still works good with other SSD?
If yes, install HWMonitor there and check components temperature and I/V sensors.

Hi! Thank you for your reply! With original ssd is even impossible to fully load an operating ststem to install from usb

With my Ssd no problem at all!

So i think problem is fixed…even if cpu is very hot..

But macs fan speed doesn’t find any problem!

Ps please help me with my other thread!

Is a lot more important! Thansk

Check all U6101 traces.
Also check all SPI Bus Series Termination resistors and traces.
Clean/remove J6100, if affected by corrosion.
