Q: No power MacBook Pro, dim MagSafe

No power, dim magsafe MacBook

Hi,

So 2 days ago I bought a used MacBook Pro, the 13" 2012 model.

I had planed to replace the hard drive for an SSD, wich I proceded to. And.... Since then, it won't power on, at all. I put back the old hard drive, did anything I could think of, still no power. When I plug my magsafe (I verified it was working with another computer) the only thing I can see is a really dim green light on the connector.

Anyone could help?

Thanks:)

MacBook Pro, Mac OS X (10.7)

    The usual remedy is to perform an SMC Reset. Please read Reset the System Management Controller (SMC) on your Mac for the procedure. Follow all the steps, even if they seem inapplicable or trivial. Make no attempt to remove the battery since your Mac's battery is not removable.

    Thanks for the tip, but I had already tried it, and since the computer shows

    no life sign at all, it does not look like it makes any difference. I still appreciate that you took the time to answer me

    Under the circumstances I recommend returning the Mac for a refund. You already ruled out the MagSafe power adapter, so the likely cause is faulty hardware that will be expensive to repair.

     

    Although a variety of causes are possible, the most common reason for the symptoms you describe is liquid damage for which a repair is almost always economically unjustified. For a definitive diagnosis though, please make a Genius Bar appointment: http://www.apple.com/support/repair/

     

    Provided you followed fundamental electronic repair principles, I doubt replacing its hard disk drive with a SSD caused the problem.

    I had already planned to go to the Genius Bar and ask for a diagnostic to know if the computer had any damages caused by the previous owner. I don't think the problem could have been caused by the upgrade I made but the computer seemed to be in pretty great condition inside. No clear sign of oxydation caused by liquid, really, nothing seemed wrong. Maybe I am just really not lucky and accidentally shorten up a circuit, and if that is the case, it was not my lucky day, because it's defenetly not the first time I make this kind of procedure and never encountered any issue.

     

    We will see how it goes, fingers crossed I find a viable solution.

    That's what I would do. Apple might charge a small fee for diagnosis, but it would be deducted from any repair you decide to have them perform.

     

    If the Mac's battery is causing the problem, evaluation, parts, labor, and a one year guarantee is only $129 US + tax: Mac notebooks Service Pricing - Apple Support.

     

    If the problem is something other than just the battery, Apple will explain your options.
