Fixing a Stuck or Broken Power Button

There may be various reasons why the power button of your phone or tablet is not functioning properly. Overuse, pressing too hard, accidental drops, moisture, dust, lint, etc., may affect its functionality negatively.

Clean Power Button with Isopropyl Alcohol

  1. Make sure your phone or tablet is turned off. If it’s on, read my tutorial to learn how to switch off a phone without the power button.
  2. Get a cotton swab or an old toothbrush.
  3. You’ll also need some Isopropyl alcohol with the highest percentage (90-99%) you can find.
  4. Dip the cotton swab or brush into the alcohol and shake off the excess alcohol.
  5. Now clean the sides of the power button gently. Clean power button with Isopropyl alcohol
  6. Ensure you get the toothbrush bristles inside the gap around the power button.
  7. While cleaning, press the power button at intervals to check if it’s loosening up.
  8. Keep cleaning until the power button starts giving tactile feedback.

Warning: Don’t use Hydrogen peroxide as doing so might damage your phone’s button.

Use Hairdryer

In case cleaning with Isopropyl alcohol doesn’t work for you, try the following on top of it.

  1. Take a hairdryer.
  2. Cover all sides of your phone with some fabric except the power button.
  3. Now blow moderately hot air on the power button.

Doing so will loosen up the stiff power button since the heat will soften any fatty or sticky deposits, the rubber/plastic component used below the button. Additionally, try these tips to remove moisture from your phone. If the above tips didn’t help you fix the broken power button, visit a service center.

I tried to mention all possible ways to lock, wake up, unlock, and restart Android devices without the power button. Getting the damaged power button fixed or repaired is the only feasible solution to make it work.
