Sostituzione Batteria nel MacBook Pro 13" Unibody, versione metà 2012

My top tip - make sure you buy good quality Phillips screwdrivers and a magnetic holder. Cheap screwdrivers won’t get the screws undone safely. Without a magnetic holder you have no chance of getting the tiny crews in and out safely.

Tip: if you have a magnetic screw mat or similar, lay the macbook over the mat to make sure it catches any screws that may decide to fall of and hide under your table

Funny, it's not her hands that are doing the close ups. :)

What's the difference between the shouldered and non shouldered screws? They look exactly the same to me.

I used the nails of thumb and pointer finger simultaneously - worked pretty fine

I whittled down ends of two wooden strips to use, along with my fingernails to start with. I used halves of a wooden clothespin, but popsicle sticks should work too.

I suspect it’s just like the special screwdriver required for seatbelts on cars – to discourage regular consumers from attempting repairs. Of course, this only encourages consumers to use the wrong tool to attempt to repairs

Dissambling my MacBookPro Premium Mid 2012 (i5-3210M 2.5Ghz) was easily, Careful with the screws, use screwdriver fitting exactly with the screws, you damage them very fast. Work very exactly, relaxed with time, consentration, good Tools and with feelings in your hands. Disconnect the Akku was easy if you take care, remove it to be safe, Two screws more, more space to work & haven`t to think about damaging someting. Apple use diffrent screws, you should have many difffrent scewdrivers. It is also good to clean everything inside, With time everything gets very dusty & dirty, don`t forget the sides and little fittings at the case. Use a pinsel, alcohol, soft peace stuff, it will look like new. If you have knowledge & experience, you can paint it in any colour or airbrushing for individualizing. You can also just polish it with a soft Politure (Sonax car Polish No1, NOT with wax or take an other light Politure you familiar & can do the job, A Laptop should serviced once a year, keeping it good working over years

First thing i do is open & cleanig everything inside,specially the cooling & fan, renew the thermal paste with an high quality product. Install the Nain System, clean up Bloatware and other unnecessary things, install standard software for daily use, additional change system components against better one (Edge to Firefox, Windows Media Player to VLC , an Office Suite and configuring everything for Data Protection, Privacy- & Indentety Protection, install Drivers from the component Manufactur (incedible effect, disable limitations, more functions, work better & faster, increasing performance, additional change the WiFi & Bluetooth Card to a better one a UMTS WWAN to an LTE Card, increase RAM with two Dual-Channel working SODIMMs, Use M2 or 2,5" SSD if no M2 Slot aviable) as System- and Software iDrive, a FAT32 formatted 32GB Partition to be safe of metaviruses comes with harmless downloads, and a big 2,5 HDD to store the user data. What does you guys think about this? Old Computer become a new life,

I livein Austria, near Vienna, if someone needs help or anything else, i would be glad to help. I always searching old or broken devices to bring them to new live. I also searching for spare parts, specilly a Bottom & Side Case and a 256GB or higher NGFF Storage Card for a Sony Vaio Tab 11 SVT1144HE (2014), some 14,1" Displays for a HP Probook 440G5 (2016), Elitebook MT 43 Mobile Thin Client, (2011), Dell Vostro 3460 (2012) Lenovo Thinkpad T440s (2014), and a Logic Board for an Lenovo Ideapad 330-15ARR (2017, damaged by Water i think) and a Logic Bord for an Alienware 17R4 with i7-6870HX & Nvidia 1080 (2018, CPU dead, maybe there is a repair Guide or workaround to bring it back to Life). I need always 8GB or 16GB DDR3 and DDR4 RAM Storage (perfectly two ident one for Dual-Channel use for Laptops, M2 SATA 6GB/s and NVMe PCIe SSDs 500GB or more and 2,5"SSD or HDD with 1TB or more and 3,5" HDD with 4GB or above. If you have some of this or other useful parts and doesn`t need them, please make me an offer, maybe

The 13 mm Tri-point screw was very tricky to screw back into place. I had to make several attempts, unscrewing and realigning the battery to get it right. The rest of this fix was very easy, but this one screw was the hardest part.

As per Rossi Macri’s comment, I also observed for step 5 that both screws are Tri-point Y0 for my MacBook Pro 13 inch mid-2012 model.

For the Tri point 3 wings or however you call them. the proper Screwdriver is really to rcommend; I manageds it with a normal flat but very small screw- driver but it slightly "damages" the screws;(a four winged screwdriver does not grip enough);

So i recommend to buy the whole package with instruments; (i had all other instruments accept the Tripoint)

the screws themselves seem to be fragile

For putting them in again its better to start with longer one but dont fasten it tight keepit loose until the short one grips.. the tighten them but not too fast.

Bought the replacement battery from iFixit but upon reassembly, the 13 mm tri-point screw (the right one) took like 15 minutes to get it properly alined. With the original battery, it was first try, as was the left 5,6 mm. Keep an eye out for that!

Oops, i missed step 5. Wait at least five hours, then charge your laptop uninterrupted to 100%. I charged it to 100% right after it went to sleep. It did seem slow to charge after that, so I reset the SMC. It now seems to be charging normally. I hope I did not damage by skipping that step.

When i charged the new battery the first time, my macbook pro mid 2012 switched itself on during charge every 2 Hours or maybe 3;

i reset the smc then it was normal again
