Where do we start

Here at Mend, we are always encouraging customers to purchase their own MacBook parts to DIY for themselves instead of frantically finding a repair shop across Singapore. While there are
obvious pros to this, there are also precautions to take note of.

For first timers, this article will cover some tips for you to follow so that you won’t be making the same error as we did (unfortunately). 

The following 10 points might be obvious to some but it will also serve as a good reminder whether you’re a seasoned tinker or picking up the screwdriver for the first time.

1. Read all about it

Be it word or video format, read and watch through the guides to make sure you familiarize with all the steps. Established sites such as ifixit has plenty of guides available or you can take a look at some of our featured guides here.

2. Examine the body 

Examine the exterior of your device for any damages before proceeding. For example, when performing an iPhone battery replacement, ensure that the display screen is taped if there are any obvious cracks before unscrewing and opening it as this would make it easier for the suction cup to stick onto the screen. 

3. Safety first

Always make sure the device is off before you proceed (Battery below 25%). When handling cables, make sure you disconnect them before proceeding to the next step. This is not only for your own safety but also to ensure your device is not damaged during the process. 

4. Check your checklist

Check that you have all the items required for the repair and ensure that you know how to use them - not everyone uses an adhesive remover on the daily basis but you would need it to remove the battery of a MacBook Pro Retina for example. Preparation is always key!

5. iSpy with my little eye

If you have not disassembled an iPhone before, here’s a warning: the screws are extremely small and screwing it wrongly may damage your phone. Prepare a small container/ medicine box with multiple compartments to categories the different screws whenever you start to disassemble it.  

6. SOS 

If possible, get someone handy that can help you when you’re trying to mend for the first time. For example that person could help with opening up the iPhone (this definitely required some strength!) or keeping track of the screws of your device.  

7. Visual aid

Use video guides on YouTube if it helps you better visualize how the repair is supposed to be executed. In addition, there will usually be audio commentary as well to further help you when performing difficult steps.

8. Deer in headlights

If you get stuck on a step, don't panic - google on how to troubleshoot that specific issue. More often than not, someone else would have experienced the same problem as you and would have come up with a solution to troubleshoot it. Read through forums for more practical help. 

9. It definitely gets easier

Once you’ve mend a few devices, you’ll definitely get the hang of it and start to notice similar patterns when repairing iPhones and MacBooks. As the saying goes, practice makes perfect.

10. Kill two birds with one stone

Fixing your device is already hard enough so why not make full use of it?

Create a guide for other users and post it on a forum or video the process for your next Tik Tok video. You’ve spent so much time repairing your device, you might as well get something out of it! I mean, besides the device actually working...

Slowly but surely

We hope these 10 pointers have been useful in starting your DIY fixing journey! Remember to always be careful for each step and not to rush the whole process so that you can quickly finish it. Even one small screw can affect the whole repair.
