macbook pro early 2011 battery replacement

I'm starting to think it might be the dc-in board or the logic board :( as nothing works. I think the PRAM reset is what actually unsets the Startup Disk selection. i've tried to do that for about at least 50 times! and none told me to choose the startup disk.Īctually I might be mistaken that the SMC reset unsets the Startup Disk since I usually combine the SMC reset with a PRAM reset. Okay, now that tells me that SMC is actually not working. Or you & your uncle have been very unlucky in finding a good battery. This could indicate some other hardware issue with either the Magsafe DC-In Board or with the Logic Board. My uncle gave me the computer, and he told me that previously it had the same problem. The only vendors I recommend people use to purchase Lithium-ion batteries are either OWC or perhaps.

Even Apple has quality issues with Lithium-ion batteries, but at least they seem to be more reliable for the most part. Finding a good third party battery is so hard that I will opt for a more expensive official Apple if they are still available which unfortunately is not the case for your model laptop. I've even had issues with batteries from OWC which normally sells very good products. I haven't had very good luck finding good quality third party Lithium-ion batteries. After an SMC reset you should choose your Startup Disk again in the Startup Disk System Preferences.Īlso, battery has 30 day warranty, should i go for it?

No, it does not change the macOS Energy Saver preferences although it will remove any selected Startup Disks. I read that energy settings reset after you do this, and my adjustments are the same that i changed myself. Option Boot the laptop and let it sit at the Apple boot picker menu. There's something about the SMC that makes me feel it isn't working. charger, wires, magsafe port and everything, and the battery is brand new)

If you know how to fix it, or if i need to change anything let me know. SMC reset, PRAM reset, remove and reconnect the battery like 3 times, everywhere i look up on the web says that SMC reset will fix it. I've done pretty much everything with no luck. it had 72% battery when installed, i started to work with it as usual, and then it suddenly shut off, so i plugged in the computer and surprise! all i got was a green light out of the cable, and the mac saying battery not charging. i installed it myself, no problem or anything. So the problem came 2 days ago when i got a new generic battery. Computer had no battery but used to work OK with the power adapter. I need a little help here, but before we talk about the problem i'll walk you through some background info: It's an old early 2011 macbook pro that my uncle gave me because he didn't need it.
