A question about the iFixit logic board for 2012 13" MacBook Pro.

I took it to the “Genius” bar and was told the problem was caused by my logic board. The genius, picked up my laptop and flexed the bottom. The lines/other disruptions showed up on the screen and the System crashed.

I was told since I replaced the optical drive with another hard drive and replaced the battery, I should take it to a specific shop to do the repair.

I took it in and the repair assistant told me not get the repair because of the VST defect and the problem can return.

Do the iFixit logic boards for 2012 13” MacBook Pro 2.9 GHz have a repaired/non systematic VST?

Thanks for any help

I'm not sure why this got moved over as the root issue was never identified properly - VST defect? I've not heard the term and I don't find any reference in the schematics.

There are some known issues with this series logic boards maybe thats the question

@danj Looks like this post was mistakenly marked as spam in the Answers forum. I went ahead and restored the original post.

@danj are you now accepting mail-in repair services?

@mayer - I was about too last year as I was without a client. But, I managed to find an opportunity that's part time which I'm giving a go. The tides may turn ;-}

As you know I'm planing on lifting my anchor to grace other shores soon.

Computers are not supposed to work with bottom flexed.

Try checking the RAM modules, reseat them in place, sometimes they are not perfectly inserted in the slot and despite they work, as soon as you put pressure on the bottom cover RAM moves a bit and causes a kernel panic as it may be expected.

I’m with @danj on this, never heard this “VST” and can’t imagine what the “genius” is talking about.

VST drives were ZIP drives made for the G3 models

@mayer Pretty old stuff, can't remember having seen that module before. Thanks for the info!

Could be a bad ram slot I would try one ram slot at a time and see if problem persists.

@mayer - Still an odd term for this series.

I still have an internal Zip drive in my old dusty Windows PC ;-}
