When you consider the labor and time involved in laptop battery repair and buying a new one, it is better to just buy a new one.
Like all energy storage devices, batteries that power a laptop eventually lose their capacity to hold a charge. If the program to check your battery status is not already on your computer, you can download and install the appropriate program. Place the new power cells in the tray, connect the electrical contacts and cover them with the plastic.
While the common rumor thus far for the new MacBook Pro 2012 models has been that they'll cut down the size to MacBook Air levels, a new tip today says that's simply not the case.
What you're seeing here is an illustration, not an actual real set of images of the casing of the MacBook Pro 2012.

SSDs have no moving parts, making them much more rugged and less likely to be damaged if dropped - very useful for laptops - and they have incredible read and write speeds that make your Mac significantly faster than a tradition hard drive. Read on to learn about finding the best SSD for your Mac and a step by step guide to installing it. Crucial is my recommendation; I have never had a problem with my SSD from them, and they have a very easy SSD Advisor for choosing the best one for your Mac. Unlike changing your RAM, swapping your boot drive (in this case upgrading it to an SSD) will mean you are effectively taking out the disk that your operating system is on and replacing it with another. You have the option of installing your operating system as a fresh install by using your install CD that came with your Mac, or if your going to boot Lion or Mountain Lion you can use the a USB drive.
Tip: Some people suggest cloning data from a hard drive to an SSD, but this is not advisable for multiple reasons. You really have a great deal of choice when it comes down to deciding what you want for your Mac.
Before you go removing the bottom of your MacBook Pro, make sure that it is turned off and disconnected from a power source - this is very important.
Tip: If you don’t have access to any of these try to use a clean hard surface, like a kitchen counter and make sure to touch a metal surface, like the inside of the computer case to discharge any static once you’ve opened it up. Now that the machine is off and un-plugged (and hopefully on a static free surface) you can take the bottom off your MacBook Pro.
In the bottom left corner, we have your hard drive - in mine there is an SSD because I’ve already done this before, so don’t worry if it looks different.
With that removed you can gently lift up your drive using the tab provided - you should only handle the drive by the sides. Your Hard Drive will have four Torx pins that need to be removed (cue Torx T6 screwdriver).
First, you need to attach the four Torx mounting pins to this drive - two of these screw into each longer side, just like they did on the previous drive. You can now place the SSD back into its bay by positioning the two Torx pins closest to you in their holder and lowering the SSD into its position.
Assuming you were successful in replacing your drive with an SSD, when you boot up your Mac, you should get to the Mac OS X Utilities section.
Now that you have a clean disk, you can close Disk Utility and pick from either a new install of Mountain Lion or restore from a time machine backup. Once you have Mountain Lion up and running, you are now ready to start using your new speedy Mac. Overall, you’re MacBook Pro should feel like a new laptop, and all it needed was a few hundred dollars (maybe less if you have a smaller size) and a bit of time. If you test the laptop battery using this method and you find that it drains power faster than it says on the package it came with, then it is time to purchase a new one.
Finding an outlet that sells new laptop batteries is faster than repairing the battery yourself. Repairing a battery is generally more cost effective than replacing the whole thing because you can retain the digital circuitry that controls it.


After you run the program, the system will generate a report regarding the overall status of the battery. This ensures that all cells will have an equivalent charge when you install the new components. Before removing the power cells from the battery tray and disconnecting the lead wires, verify whether the laptop battery needs to maintain a charge in order to retain any data in a memory, such as the resistor value or fuel gauge function.
Batteries normally remain in the correct position, but you may need to bond them into place if the wires were damaged when the power cells were removed.
A laptop battery that cannot be turned on when the circuit is connected to a ground may require a special code from the manufacturer. He is the creative director for the BatteriesInAFlash blog and mastermind of all technology with the company.
What we've got here instead is a new case with no optical drive and the space that was used up by the optical drive being used for a much more gigantic battery and an SSD boot drive to take down costs for the unit substantially - that SSD being just for the OS. The top image is indeed real, the bottom is an illustration of what would happen if Apple went the way we're speaking about here. With all that extra battery, the MacBook Pro could potentially have a much more densely-packed set of pixels in its display or could of course allow for days of battery time without worry.
Please note that this was performed on a 2011 MacBook Pro, but the installation will be the same for almost all other MacBook Pros. You can find these online or at local stores, or you can buy a toolkit which will have all you need and other small useful kit.
While all SSDs from the big brands (like Crucial, Corsair, Intel etc) are likely to be a great step up from your preinstalled Hard Drive, there are some factors to take into consideration.
It’s also worth checking out reviews of SSDs that you may consider buying, because there could be noted firmware issues with that model for example.
If, however, you really want to get one of the best, I would suggest taking a look at the Corsair Neutron GTX.
If, however, you want to migrate your data from to the new SSD, you also have a few options, most notably using a Time Machine backup or one of these methods.
I recommend that you either do a fresh install, or use a Time Machine backup once you’ve installed the SSD.
Personally, I would recommend that you back up all your important documents to a USB drive or some cloud backup service, and then do a fresh install of Mac OS X.
Static can fry your Mac’s internals, so its very important to make sure none of it builds up. This isn’t absolutely necessary, but it's a very easy to step to make things a little safer and less likely to go wrong. To remove the hard drive we first need to detach the retainer bar that keeps the drive locked in position. Once you're finished, you can now peal off the plastic tab and place it on your new SSD in the same position as it was on the hard drive.
Then gently connect the SATA cable into the new SSD, making sure you’ve lined them up correctly. To do this, you simply press the connector back into place - be cautious, as with any connection there are pins that can be damaged if it is forced. Depending on what method of backing up you used, or whether you decided for a fresh install, will determine what your next steps are.
From here I recommend going into Disk Utility and formatting your drive - not essential because it’s a new drive, but it doesn’t take long and it could avoid problems later on if there was something already on the SSD. Choose which ever method you would prefer and simply follow Apple’s steps to setting up your Mac with OS X. Having introduced your Mac to an SSD, you should notice a significant boost in performance, most notably boot up times (which some have reported to be as low as 10 seconds with an SSD), and application load times. Purchasing a laptop battery is generally much cheaper than repairing it yourself because it comes with minimal risks.
Laptops usually have a battery check program that enables you to evaluate the condition of the device.


In these instances, you must maintain a secondary power source to the circuit while replacing the worn out cells. When soldering, it is critical that you avoid excess heat that can damage the cells or electrical circuit.
It's not unlikely that this will be the way of the truth in the very near future - Apple has presented a non-disk future in its MacBook Air models for several generations now, and with the Mac App Store live and in action for software, we'll see the MacBook Pro 2012 models hitting stores with no room for a DVD without a doubt. You may also notice that I don’t have a hard drive in my MacBook and it is in fact already an SSD - this is because I have previously upgraded, but the process is exactly the same if you are upgrading from a hard drive or another SSD. A fresh install tends to make your Mac run faster, as it won’t have any unwanted files or apps that you’ve downloaded and forgotten about.
Remember where the screws came from, as the three on the top right are longer and need to be replaced there. To do this, you can just use your finger nails to gently pry the connector free from the logic board. Gently remove the SATA connector from your Hard Drive and place the connector back down on the tray. The last thing to do is put the bottom of the MacBook back on and screw it in, starting with the three longer screws first.
If you are either doing a fresh install or a backup from Time Machine, there are a few small steps from here to getting your Mac up and running - if you are using another method such as Carbon Copy Cloner, you should do a quick Google search to see the process. Select your drive (should be called Macintosh HD), under the Erase tab select the ‘Mac OS Extended (Journaled)’, pick a name if you want, and click erase. First of all, it still might not go back to being the way it was when you first bought it, and then secondly, you might cause considerable harm to your laptop, or even worse, yourself when you repair the battery yourself. In addition, you can always replace your laptop battery with original or compatible versions of it.
The program will recommend that you replace the battery when one or more cells have low capacity or have completely lost the ability to accept a charge. To avoid damaging your laptop, you must use power cells with the same chemical composition and power rating recommended by the manufacturer. It is recommended that you take precautions like grounding yourself with a small wrist band, or use a static-free matt. The bottom plate may need a little (please remember ‘little’) bit of force to remove it, but once you’ve done that, you can set it aside and bask at the glory of your MacBook Pro's internals for a few seconds. He has been using Apple products for several years and has developed a striking fondness for them - leading him to have quite a collection of Apple devices. There is a greater risk of chemicals leaking from the batteries in the laptop and causing irreversible damage or the battery dying all together.
Before you repair your laptop battery, ensure that you read and understand the terms of your computer warranty.
Record the model number of the battery and the part number of each cell so that you order the correct replacements. This may require the assistance of a voltmeter to properly determine which are the positive, negative, clock and data connections for the battery circuit. For instance, to repair a Dell 1545 battery, it would cost you an average of AED 246 for the repair parts and an additional AED100 for labor while purchasing one would cost AED219 on average.
Upgrading RAM was a relatively cheap way to increase the speed of your Mac - it did so by making your Mac run smoother if you have multiple applications open at the same time and generally allowing your Mac to do more without slowing it down - but adding an SSD will be make your laptop run faster than it ever has.
