Hi forum.
I'm working on a macbook pro, model a1708, that is running extremely slow.
Everything on it seams to work just fine, it just works extremely slow; painfully slow; especially running macos (windows and linux actually run OKish on it, slow, but usable).
One other symptom of the problem with the machine is that the fan is always running at full speed.
This machine has been worked on by someone else previously; they tried to repair it, but with no success. The motherboard does have sings of being worked on, but it all looks good/OK; like... -
Hi guys i have my personal MacBook Pro 2015 820-00165 board that was working fine for more than a year and one day stopped working on my original Magsafe charger. It was turning on with my bench power supply. Opened it up and while diagnosing that somehow i ended up with a shorted smc.The line which was shorted was SMC_PM_G2_EN.

hi all, I have a problem with my macbook pro 15 inch, late 2011 with SSD, AMD Radeon HD 6770M dedicated video card and Intel HD 3000 integrated card.

I also changed the battery to a compatible one and the problem persists. Now for a few days I have also noticed that the computer after a few minutes from starting it jerks and becomes very slow. However, this problem arises in several ways:

Hi guys
820 00850 board here, clean, no previous repair.
Had a short on PPBUS, I found the problem, was shorted cap C8150, replaced and macbook boots.
Problem is its very slow.
It would boot to login screen eventually, but mouse and keyboard very erratic and slow to respond.
When I tried Internet Recovery, it takes a few hours then fails on 2005F error.
When I try to boot from USB stick, it lets me select the stick, then just a blank screen and goes no further.
I restored using DFU... -
