Why won’t my LG K40 turn on?

The main cause of an LG K40 not turning on may be due to software or battery related issues. Whatever the case, this can be disappointing. However, there are other issues that can prevent your LG K40 from turning on. Some of these include:

Outdated software Your LG K40’s software may be outdated, which means that the drivers need to be updated. As a result, there will be interdependencies where the entire system will crash if one part of the system crashes. In this case, it is necessary to update the driver and install them again. This can fix many problems within your device and make sure it is working properly.

Hardware related problems Hardware, such as the battery, may be damaged beyond repair, such as leaking or other physical damage. This can be the result of charging the LG K40 too much or dropping it and causing damage to it. In this case, you’ll need to replace the hardware to fix it. If your battery is damaged, be sure to replace it immediately. Once the battery is replaced, you can safely restart the LG K40 and continue using it.

What to do if LG K40 won’t turn on?

If you are wondering, «What to do when an LG K40 won’t turn on?», this guide is for you. It can be due to many problems that prevent your LG K40 from turning on. The following are possible solutions that can help solve the problem.

1. Check if the LG K40 is charged

As is often the case, the most obvious cause is usually the right one. If you haven’t noticed any signs of your LG K40 malfunctioning before, the problem could be as simple as a lack of charge in the battery. To solve this problem, try the following tips.

Check the connections First of all, check the obvious points. Have you remembered to charge the LG K40? Is the charger partially detached from the power outlet? And is the power outlet turned on?

Clean off dirt and dust Next, make sure there is no dust, dirt or other impurities clogging the USB port of the charging cable or the charging port of the LG K40. Remember that connections are delicate. The best way to remove dirt from the ports may be to use a can of compressed air.

Check the cable USB charging cables are notorious for malfunctioning on a whim. You can check the integrity of your cable by using it with another device and seeing if it works.

2. Power cycle the LG K40

We’ve all experienced a frozen phone. The screen doesn’t respond and none of the buttons work. But did you know that it’s also possible for an LG K40 to freeze when it’s turned off?

If your LG K40 won’t turn on, one solution is to perform a power cycle. Press and hold the LG K40’s power button for several seconds. You may need to hold it for 10 to 30 seconds.

3. Check the LG K40 battery

If your LG K40 has died and won’t turn on or charge, but you’re sure your charging equipment is working and a power cycle hasn’t solved your problems, it’s time to turn your attention to your LG K40’s battery. It could be the reason why your LG K40 won’t turn on.

Most phone and tablet batteries start to lose quality quickly after a few years of use. Eventually, they run out of power completely. Other types of damage can also irreparably affect the battery. Liquids, drops on hard surfaces and extreme temperatures can render a battery useless.

Check that the battery is receiving power. After plugging the LG K40 into the charger, wait a minute to see if the battery icon appears on the screen.

If it does, the battery is fine and you can proceed with the next steps. Alternatively, you may see a small red (or other colored) light flashing. If so, it means that your battery does not have enough power to turn on or display any content on the screen. Let it charge for 30 minutes and try again.

Don’t see the battery icon or a light? That could mean your battery is dead and needs to be replaced.

4. Check the LG K40 screen

You may be frustrated that your LG K40 won’t turn on when, in fact, it may be on without you even realizing it. A cracked screen can give the impression that there’s no power.

Fortunately, it’s easy to tell if the screen is the culprit. Press and hold the power button for 30 seconds to make sure the LG K40 turns on for good, then wait at least two minutes for the boot process to complete.

Now, call yourself from another phone. If the LG K40 beeps, your screen is to blame. Remember that sometimes you can replace the screen yourself, but it will void the warranty.

5. Use a computer to turn on the LG K40

If you still can’t turn on your LG K40, you may be able to force it on your computer. Google provides a somewhat convoluted series of steps you can follow. We’ve simplified them below:

Connect the LG K40 to the computer using a USB cable.
Let it charge for 15 minutes.
Disconnect the cable from the LG K40 (not the computer).
Reconnect the cable within 10 seconds of disconnecting it.
Charge LG K40 for another 30 minutes.
Press and hold the power button for five seconds.
Press Reset on the screen.
If Reset doesn’t appear, press and hold the power button for an additional 30 seconds.

6. Factory Reset (erase data) LG K40

If connecting your LG K40 to a computer has not solved your problem, then performing a «Factory Reset» may work. This technique requires you to first reboot your LG K40 into recovery mode and then perform a «Factory Reset». Remember that this method will erase all the data on your LG K40, so do it only if you are willing to risk losing your data.

Here’s how to fix LG K40 won’t turn on at all with a factory reset:

Step 1: Enter your LG K40 into recovery mode after turning it off.
To do this, you have to press «Volume Down + Power» at the same time. Keep holding these buttons until the LG K40 logo appears and the LG K40 restarts again. Step 2: Now, you can factory reset your LG K40.
Use the «Volume Down» button to scroll up until the «Factory Reset» or «Wipe Data» option appears.

7. Your LG K40 might be unusable

If none of the above has worked, it may be time to face the reality that your LG K40 won’t turn back on and you need a new phone. Remember that some phones are specifically designed for use in dirty or difficult areas. If you find that you keep encountering stuck ports, one of these devices might be the best solution.
