My Problem

My 2009 MacBook Pro had a battery warning for about 2 years, and the last year was the "replace now" warning. I have had very little money so I kept putting it off. Well I'm in school and need it for my classes and it was really starting to act up and wouldn't hold a charge for even 5 minutes being unplugged. I brought it to my local apple store "simply mac" and they informed me that they no longer make my battery at all. The guy was super nice though and told me just what to look for in a battery online. I did some research and I went with this site because it seemed legitimate and had many reviews and very detailed instructions with great pictures.

My Fix

I have had absolutely zero experience doing any sort of repair or disassembling any computer, heck, this was my very first computer! It made me nervous to try something like this on my own. With the help of the guy at the store as well as the details of this site, I was able to change out the battery by myself. The only trouble I had was when I tried to put the screws back in the battery to hold it in place, I couldn't get it to fit properly. I figured out the my old battery actually was a little broken and left little plastic shards in the corners by the screw holes. Once I got that out of the way it was a breeze. I did not expect this to go as well as it did. I am very satisfied with my purchase.

My Advice

If you don't have special screwdrivers, what worked perfectly for me was a screwdriver meant for glasses repair. It was perfect!

My Problem

My Macbookpro would not power on. The charger was constantly Orange.

My Fix

I replaced the battery with a new one(which took all of 15 mins)and it fired right up!!!

My Advice

My advice is make sure you read the tutorials on the ifixit site. Go through it in your head what you want to do. After you have read them and have a clear understanding of the work involved, then start.

My Problem

My mid-2009 Macbook Pro would keep a charge for less than an hour and I always had to have it plugged in. Decided to replace it myself!

My Fix

Pretty smooth repair. I didn't purchase the screwdriver because I thought I had the right one in my toolkit. I had to use a poor-fitting one and a ziploc baggy to unscrew the necessary screws and put them back. I put the baggy on the screw and used quick, short twisting motions to get the screws out.

My Advice

Purchasing the $7 screwdriver would make the job easier. It doesn't come with the standard screwdriver kit that iFixit gives with a hard drive replacement. (I did that about a year ago for this macbook, switching to a solid state drive.) Thanks iFixit for keeping my Macbook Pro alive & healthy without breaking the bank!

My Problem

My battery was at less than half its original max. I couldn't work on an unplugged computer for more than an hour.

My Fix

Smooth at silk. Remove screws, pop the cover, unplug old battery, plug in the new, voilà.

My Advice

The computer's clock will most likely reset once you put he new battery in, but that's about the only thing I found I had to fix post-installation.

Oh, and it was a tad dusty inside, so some canned air might be good.

My Problem

Slept the MBPro, got up in the morning and the sleep light was off. Pushing the battery charge button on the left side produced a rapid and very odd fast couple of flashes I'ld never seen before from 2 of the LEDs on the left side battery indicator. I knew the battery with 450 cycles was dead.

My Fix

Once I got the iFixit battery, changing the battery out was easy & routine. But, you NEED the tri-lobe screwdriver, which I didn't see listed on the iFixit site as I was probably in a rush.

The question was what would happen on boot up? Battery indicator lights initially on the new battery showed charging was not accepted from the charger brick which was odd, but understandable after the MBPro shut itself off with the original battery failure in sleep mode.

The question was what would happen on boot up? Battery indicator lights indicated 70%; plugged in charger and hit the power key.

An odd sequence then occurred as if the MacBook Pro went into a deep hibernation, but didn't power off when the original battery suddenly 'went off.' It also was apparently not upset during the battery replacement apparently. I wasn't prepared to document exactly what happened, but hitting the Power On key did not cause the MBPro to go through the cold boot routine, but just resumed as if coming out of hibernation.

Once up and running & then restarting once and, everything was back to normal.

Given the MBPro is 5 years old and used every day, I think it is time to buy a used MBPro as a backup as I don't want to upgrade until the Skylake MBPros hit with Thunderbolt 3.

My Advice

I really can't say how to handle a MacBook Pro properly when the battery instantly fails while in sleep mode and then won't come out of sleep with the charger plugged in, no doubt as a safety procedure.

This type of battery failure seems to have triggered a safety mode within the MBpro and it would not wake even with charger power so it could be properly shut down prior to the battery replacement.

I don't know if there is potential for corruption in this mode, but would like to know. Apple must have some notes on this to help other people.

My Problem

My MacBook Pro, five years old, and had a dying battery. I had put in a SSD last year and other than that it fit the bill. Now with my new battery I can use it for a couple of years. By Investing the money that was saved that would have been spent replacing the MacBook Pro, I can now see what they have to offer down the road. This works just fine for all that I use it for.

My Fix

Very well, took around 20 minutes. I had all of the recommended tools laid out, a good light and a dish for the screws. The instructions were perfect. I did have my iPad by my side with the whole procedure to refer to as I went along.. Not that you would pass it on but I am over 75 thus anyone younger shouldn't hesitate to do this repair.

My Advice

Have a device by your side to refer to while working. The visuals from your site are so helpful. Also have the correct tools on hand. Might think about buying a white board to locate the removed screws as they are taken out.

My Problem

For over a year, I've been seeing the 'Service Battery' message on my laptop. The power was running down fast enough that I needed to carry the power cord with me, everywhere I went. So, I decided to make my life easier, by finally replacing the battery.

My Fix

Once I had the right screwdriver (P6) this was the simplest of repairs. Once I had the back off the laptop, it was just removing three screws and one plug. The new battery connected easily, and with a little pressure, the new one seated in place. After that, it was just a matter of replacing the battery screws, and closing up the case.

My Advice

The spudger seems like a small thing, but it's nice to have it for holding back the tab over the last screw. It decreases frustration, more than anything.

The P6 screwdriver does fit, but you may need to press down more firmly to get the screw to turn.

I grounded myself, and took off my jewelry before getting started.

My Problem

Yikes! My MBP batter bulged so much, I couldn't use the trackpad! It would even rock back & forth on my desk because the battery was trying to get out.

My Fix

The repair went incredibly smoothly thanks to the iFixit guide & tools. I ordered all the tools I needed for the job and the battery through this site, and it could not have made things easier.

My Advice

Don't wait! If you notice something, even something small, a bit weird going on with your computer, do some research at iFixit & get it solved asap!

My Problem

Battery would not last 1 hour.

My Fix

Went fine. I did not have the Y screwdriver and had to go find one.

My Advice

I did not see a kit with the screw drivers included or I would have bought that. I recently bought a new battery kit from you for a IPhone 4S and it included the screw drivers.

Do you offer screws? I am missing several from my Macbook Pro.

My Problem

The trackpad in my 2009 era MacBook Pro had stopped functioning normally, and I was prepared to attempt a trackpad replacement - far more involved and costly than a mere battery replacement.

Upon opening up the Mac to investigate the trackpad situation, I realized that the battery was swelling up, and in the process pressing against the underside of the trackpad. I removed the battery and discovered that the trackpad worked perfectly.

Thus, I ordered a new battery instead of a new trackpad.

My Fix

Piece of cake to replace the battery - about as easy as a MacBook Pro repair gets.

My Advice

Just make sure you have the right tools required to remove the battery, as the screws that hold the battery in place aren't standard phillips screws. iFixit's screwdriver kit is fantastic because each tool is imprinted with its size, making repairs a breeze.
