MAGSAFE Damaged or What!? Not charging MPB 8,1

by tevcrvm / February 24, 2014 11:12 PM PST

Hi. i boutght this (Late 11' MBP 13") item has less than a week of use since it arrived last friday 02-21, the Magsafe adapter stopped working normally on sunday Feb 23rd. The laptop was left on by saturday night (Feb 22nd) downloading an OS update and next day (sunday Feb 23rd) it showed like it was not connected. Didn't recognized the power adapter for a long while, then it did, then again when it was unplugged, didn't recognized it again. The laptop was off for about a day, then plugged up again last night (Feb 24th) and it recognized the power adapter, then unplugged it to check it was an isolated incident, but No, it did NOT recognized the Magsafe again, so the fail persists. Please I'd like your help about this. I already tried to reset de PRAM, SMC (but don't know if it has indeed reseted) and tried to update SMC and EFI but one of them told me that the software was incorrect for the hardware. Please help me, I want to completely Enjoy my Mac

Seems like a warranty case. Back to the shop for a repair or exchange.

I bought it used my friend, and I'm not at the states, I sent it to Venezuela. No other comments whatsoever regarding the plug or some soft/firmware cause?

Software cause!

OK, that one is easy. Reload the OS and if it's that, it will work.

HOWEVER with laptops the simple test is this. Don't even need to turn it on. Just plug in and it should charge.

As to your "firmware" cause the only time I ran into that was someone that thought they would install some crack bios. Very strange and they had dozens of dead laptops. I just nodded and said thanks but no thanks to their business.

I re-read your top post and it sounds like it needs repair. If no shop in your country, search for international repair options.

Thanks Bob. How come do I Reload the OS? remember I'm a complete noob at Mac OS so I'm struggling with every possibility here.

I may think it's a firmware/corrupted software stuff since as I told you, I came to work all day yesterday and when I returned home last night just plugged it (while still OFF) and it Did began to charge. Turned it on a while later and worked nicely, but when I unplugged it, it didn't recognized the power cord again. That's the weard stuff.

BTW I tried also plugging it to a UPS and nothing, didn't wanted to charge again.

Reload would be per Apple's instructions.

I used google and it appears Apple documents this. As I don't duplicate the web I think you should try using Apple's own instructions.

If it doesn't want to charge, either it's charged enough or is busted.

IDEA!!! I have run into folk that don't understand why a laptop won't charge when it's done charging. I wonder.

Battery indicator
by tevcrvm / February 25, 2014 3:45 AM PST

It can't be charged since the battery indicator tells me a number <100% bob, and it's depleting continously as I use the MBP.

this may seem a little simple,

but how about changing out the power adapter to see if the power adapter is capable of doing the job.

They do fail.

How much less?

One of the new laptops at the office is using a battery life extension system and it won't charge until it hits 79%.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
