Physical damage to the power button is usually obvious after taking a drop or a knock, however other problems with your iphone may emulate a power button problem.  If your iPhone battery has failed the power button will not turn it on. If the iPhone charging port has failed or is damaged the battery won't charge and the power button will not turn on the iPhone. In some situations an LCD screen failure could present as a power button problem.


When replacing parts does not provide a solution or resuscitate your device, the only explanation is a failure of the Main Board or the Logic Board.
When a device suffers damage, the obvious problem(s) appear to be a component, for example a screen or a charging port. These component failures are readily and immediately experienced by the user to be the proximate problem. Replacing the damaged or non-functional component would seem to be the obvious solution. Thus, a user comes to The TechKnow Space to have this problem remediated/repaired. Typically the doctor (our seasoned technicians) have no problem doing this.
Sometimes however, replacing/repairing components turns out to be an exercise in futility. Further diagnostics establishes the problem to be resident in the Main Logic Board. The replacement of these logic boards is prohibitive and best left alone. It’s time to move forward to a new device.
Bear in mind that these mainboard failures are a result of the initial damage to the device that prompted a visit to the repair shop even though it is not intuitively obvious.

iPhone 6 and 6 Plus Power Button Replacement Toronto Mississauga

The power button on your phone is vital to locking the screen to prevent pesky butt-dialing (my butt always calls the pizza place) and also for waking your phone back up from a locked state or powering it down completely (although in this day and age, turning off your phone is probably less common than chewing your own arm off). This button is also sometimes referred to as:

  • The sleep/wake button,
  • The on/off button,
  • The hold button, or
  • The lock button.

The power button does more than just turning the screen on and off, or at least it does in iOS (Android users are not as lucky, unless you are willing to download a totally new OS, or reprogram the button yourself – both options have risks and rewards attached). The lock button, when pressed at the same time as the home button, saves a picture of what is currently displaying on your screen. This is called a “screenshot.”

The lock button on the iPhone 6/6+ has been moved from the top of the phone, like in all the previous models, to the side of phone. Reviews from users and consumer blogs have been divided pretty evenly. Some users have adjusted to the change fairly seamlessly while others have noticed issues with the placement of the button directly opposite to the volume adjusters on the other side of the screen.

According to these users, the way both sets of buttons are placed on the phone makes it pretty difficult to avoid pressing both sets of switches when you only want to hit one. Problems associated with the new design as noted by users have been:

  • Pressing the volume button accidentally and opening the camera app and then taking photos without meaning to (the volume buttons trigger the camera shutter when the camera is on)
  • Locking the phone instead of changing the volumes
  • Having to place your hand in a weird way to avoid either of the above issues (which is fine if you are some kind of hand contortionist or double jointed, but not for the rest of us).

If the power button on your iPhone 6 or iPhone 6 Plus is not working, the current workarounds built into the software are pretty unwieldy and annoying to use. To lock or power down your phone without a hold button, you need to:

1. Search through your settings

2. Turn on Accessibility/Assistive Touch

3. Create a shortcut to use the Assistive Touch feature because without it there is a pretty annoying grey box taking up a portion of the screen

4. Triple- clicking the home button will activate the Assistive Touch menu (which is additional wear and tear on the home button, on top of your already malfunctioning lock button)

5. And then select the function you want, lock or screenshot or camera, etc.

You need a fully working phone. There’s no question about that. So why would you live with a broken phone? When you bring your iPhone to the Techknow Space for a power button repair, you will soon be able to do all the things you used to with your phone, like:

  • Using the power button to silence incoming calls, or dismiss the call entirely (click the button once for mute, twice to reject the call)
  • Take screenshots of what is currently displayed on your screen by clicking the home button and the power button at the same time
  • Lock and unlock your phone’s screen with one touch
  • Turn the screen on while on a phone call

Don’t settle for less with your broken iPhone. Don’t struggle daily to use your phone. Phones are supposed to make your life easier, not more frustrating. Bring your iPhone to the Techknow Space and get the lock button replaced within one hour by our certified, expert technicians.

Apple has admitted to problems with the power button on previous models. They have even been sued a time or two in the US over the faulty construction of the cable which connects the button to the rest of the phone’s guts, especially in the iPhone 4 and 4S. But that doesn’t exactly mean they are eager to help users fix the problem. That’s not to say you should try fixing the problem yourself either.

Fixing the power button on your own is a complicated mess and really, who needs more mess in their life? Unless you’re Mr. Clean or maybe an army of Roombas (or is the plural Roombi? Roombus? Roombopodes?), no one wants a messy situation. Just let us do the hard work for you.

To fix the lock button yourself you would need to:

1. Remove all the itty bitty screws from the outside of the phone

2. Carefully take the screen off. This is not as easy as it sounds: you can run the risk of shattering the glass or damaging the connecting cable. This step also either requires a special suction cup tool or very steady hands and a good quality suction cup. (Not one of those ones that slide off the car window 30 seconds after attaching your fuzzy dice to the windshield.)

3. Veeeeeeeeery carefully undo the clips holding the screen to the frame and disconnect the cable between the phone and the screen

4. Remove more screws – don’t mix these ones up with the other ones from the outside (still think this is a good idea? The difficulty level shoots up soon, hope you’re ready for it)

5. Pry up the cable connectors BUT not the actual sockets of the home button, digitizer and display (you might need an old timey Sherlock Holmes-type magnifying glass for this (ok, you don’t actually need an old timey one, but those totally look cool, right?)).

6. Remove EVEN MORE screws (also don’t mix these up. By this point you should be drowning in loose screws – and I don’t just mean the ones from the phone haha)

7. Remove internal cables powering the phone.


9. Remove the antenna cable and logic board – also very important parts


11. Finally!!! You have reached the power button. You did it! Now all you have to do is install a new one and do all of that IN REVERSE.

12. Good luck!!!!!!

I had my iPhone screen repaired at this establishment today and my experience was awesome. Quality work was done in a quick hour and the staff were extremely helpful/professional. Will definitely be coming back here in the future.


iPhone 5 Power Button Replacement Toronto MississaugaYou may not notice it, but you always tap the power button of your iPhone 5, 5C or 5S to lock it before you put the phone back into your pocket. This means that you would press this button many times a day, resulting in thousands, if not tens of thousands, presses every year.

Over time, the power button of your iPhone may develop problems: it might stop responding, or, more commonly, fall inwards and get jammed. Don’t try to replace the power button by yourself. The power button is part of a complex cable assembly, which requires complete disassembly of the iPhone, with many difficulties and pitfalls. We are sure you don’t want to be left with a $600+ paperweight. A much better solution is to come to The TechKnow Space in Toronto or Mississauga to get the power button replaced. Our expert technicians can replace the power button on your iPhone 5, 5C or 5S within an hour, while you browse our wide selection of accessories or enjoy a coffee in our lounge.

iPhone 4, 4S Power Button Replacement

iPhone 4 Power Button Replacement Toronto MississaugaA power button on an iPhone 4 and 4S is one of the most used components, which you use to lock your phone many times every day. It might develop a problem, eventually, like it might stop responding, get stuck or just fall out.

You unlock your iPhone 4/4S without a working power button (or lock button) by tapping the home button or plugging the charging cable in. To lock it, however, you would just have to hold the phone and wait several minutes for the screen to autolock itself. An easier solution is to just bring your iPhone 4 or 4S in to the TechKnow Space, where our trained techs will repair your iPhone 4 power button in 1 hour.
