How to Insert the Inclusion Button of Xiaomi Redmi Note 7: All Ways + fault-solving

Xiaomi Redmi Note 7 is one of the most popular smartphones of the brand, but even he eventually has problems with the power button. It stops responding to pressing, then requires too much effort, then completely "falls" inside the case. If you are faced with the fact that the power button does not work, stuck or dropped out, do not rush to carry the phone to the service: in 80% of cases, the problem can be solved yourself.

In this article, we will look at all the possible causes of a power button failure on the Redmi Note 7, from the usual contamination to mechanical damage to the board. You will learn how to disassemble the phone without risk, what tools you will need to repair the button at home, and what to do if the button does not work after replacing it.

Important: If your Redmi Note 7 doesn’t turn on at all (no charging response, no vibrating, screen black), the problem may not be in the button, but in the battery, display plume or firmware, in which case, first check the other components.

Why is the Redmi Note 7 power button broken?

The power button on the Xiaomi Redmi Note 7 is a mechanical element that can be pressed for about 50,000 times (according to the manufacturer), but in real life, it fails much earlier.

• 🔧 Mechanical wear: over time, the spring mechanism inside the button loses its elasticity, which causes it to stop “bouncing” back or requires a strong press.
• 💦 Moisture or dust: Even if the phone is not sinking, condensation or small particles of dirt can block the movement of the button.
• 📱 Fall or impact: after physical exposure, the button can “drown” inside the case or move away from the contact on the board.
• ⚡ Short circuit: if the phone was charged with a non-original cable or it overheated, the button control chip could burn.
• 🔄 Incorrect assembly after repair: if the phone was already disassembled (for example, to replace the screen), could damage the plume of the button or connect it incorrectly.

Fun fact: on the Redmi Note 7, the power button and the volume button are located on the same flexible plume, so if one button stops working, the second one can soon fail, which is due to the fact that the plume wears out evenly.

⚠️ Warning: If the power button is stuck when pressed, immediately remove the battery (if possible) or discharge the phone before turning off. Prolonged closure of the contacts can lead to overheating of the board and failure of other components.

How do you check if the button is really the problem?

Before disassembling the phone, make sure that the power button is faulty. Here are 3 tests to help diagnose the problem:

1. Charging response check: connect the Redmi Note 7 to the charger. If the charge indicator appears on the screen (even without pressing the button), then the phone is basically working, and the problem is exactly in the button.
2. Alternatively, try turning on your phone without a power button -- detailed methods are described in the next section. If the smartphone turns on, the button is faulty.
3. Volume button test: press it several times, if it works normally and the power button doesn't, it's probably the mechanical part (not the plume or the board).

If the phone does not respond to charging, does not vibrate or warm up, the problem may be:

• 🔋 Battery (swelled, completely discharged, disconnected contact);
• 📶 Display plume (if the screen is black, but the phone vibrates when charging);
• 🔌 Power board (charge controller or main chip burned).
