Smartphones from any manufacturer can break down periodically, and the on/off button of a mobile device especially often fails. But here it is worth understanding that the cause of the key’s incorrect operation can be either mechanical damage or a software failure. In some cases, it is enough to hold the button a little longer and the mobile phone will turn on, but in others, it simply does not respond to pressing. In the event of such a breakdown, you can try to turn on the smartphone; there are several methods for this.
Why the power button may be faulty
When your favorite smartphone gets old and breaks down gradually, you can mentally prepare for buying a new gadget. But what should you do if a breakdown occurs suddenly, for example, water spills on your mobile device or it is accidentally dropped? If the device looks damaged after this, then it is clear that it should be taken in for repair. However, it happens that the device looks completely intact and simply does not turn on.
If there is no response to switching on, several possible breakdowns can be assumed.
- The most common cause of this type of problem is accidental flooding of the mobile device with water or other liquid. If such a problem occurs, then you need to disassemble the mobile phone as soon as possible and dry it with a hairdryer. In this case, dry with cold air, otherwise the contacts may be damaged;
- A common cause of such a breakdown, especially on Chinese-made smartphones, is a failure of the operating system. Such a nuisance can happen when the mobile device is turned on incorrectly or when virus software is introduced into it. As a result, important system files are damaged, causing the operating system to load incorrectly. Only a complete flashing of the mobile device can help here. You can do this at a service center or yourself, having previously installed the desired program;
- The last reason is mechanical damage to the mobile device. Such a nuisance may be a consequence of the tube falling or physical wear of its components. In this case, repairs are often impossible, but if necessary, you can try to turn on the mobile phone without the POWER button.
It’s worth at least trying to turn on your mobile device, since it can always be taken in for repair. There are several methods that we recommend trying.

For some smartphone models, such as Samsung Galaxy or iPhones, a failed power button will not cause any inconvenience at all, since the physical Home button located under the screen? will allow you to wake up your mobile phone.
In addition, you can turn on the sleeping device in another way by touching the display twice. But, many Android smartphones are not equipped with physical control keys, so turning them on is more problematic.

Replacing the power button
To fix a problem with the power key, you need to replace either the button itself or the electronic key on the internal board that transmits the signal.
Replacing the outer element can help if the element has fallen out of the housing, is cracked, or has a cavity in its base where the stiffeners have broken. The procedure is only available if the user can independently disassemble the device body. To carry it out, you must have a similar physical key from the donor device or purchased in a store. It is enough to disassemble the case and install the button in the appropriate grooves.
If the problem lies in the electronic component, or the smartphone case cannot be disassembled at home, then it is better to contact a specialist.
As a result, individual controls may fail.
