Samsung Galaxy S5 won’t turn on unless the battery is pulled out and placed back in

For Samsung Galaxy S5 owners, the Android 5 Lollipop was the most anticipated update until they discovered it was accompanied with bugs, problems and whatnot. One of those problems is power-related; the phone turns off without apparent reason and refuses to turn on.

In this post I will address one problem reported by our reader that is related to this issue. According to her, the device did an update to Lollipop in the morning but turned off without apparent reason in the night of the same day and the kicker is it wouldn’t turn back on.

Drained battery? Maybe. But let’s try to go beyond that. Here’s the actual message of our reader…

Yesterday it did a software update in the morning. About 9pm last night it shut off and wouldn’t turn back on. I took battery out and turned back on which took awhile. Today it has already turned off 5 times and then vibrates but wont turn on until i take battery out and put back in. I have missed important calls. I now have to look at phone constantly to see if its still on. HELP!

Troubleshooting

The purpose of this troubleshooting is to know what happened to the phone, what caused the issue and how to fix it. As far as the statement of the owner is concerned, the problem is caused by the firmware update. But then again, let’s try not to overlook the obvious.

Step 1: Charge the phone

The owner didn’t mention she tried to charge the phone after it went dead so this must be the first thing that needs to be done as it could be just a drained battery.

This step would also give us an idea about the integrity of the phone’s hardware. If the charging signs show, like the LED indicator and the charging icon, then the phone must be okay. Just allow it to charge for, at least, ten minutes.

Step 2: Attempt to turn it on after charging

Ten minutes of charging is more than enough to power the phone if the issue was a drained battery. So, attempt to turn it on after a few minutes of charging.

If the phone turns on, continue the observation if it turns off on its own but if not, then read this post instead: How to fix Samsung Galaxy S5 that won’t turn on [Troubleshooting Guide]

Step 3: Wipe the cache partition

Assuming the phone turns on just fine but shuts down on its own, then you must try wiping the cache partition considering the fact that you just updated it to lollipop.

During updates, some caches and data become corrupt and if the new system continues to use them, that’s when conflicts are created. Clear these files so the phone will be forced to create new ones and aren’t obsolete.

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Step 4: Verify the Power key isn’t stuck

This is optional but also important since the owner said the phone turns on and turns off on its own and then vibrates. She didn’t really say if it goes into a loop or how frequent the phone shuts down but it’s necessary.

Don’t worry, it’s easy to check if the Power key is stuck or not; just press it and if it snaps, then it’s not stuck. Otherwise, try pressing it multiple times to see if you can fix it. If not, then you really need help from a technician.

Step 5: Perform the full hard reset

If the phone turns on and turns off by itself, it’s either the hardware that’s causing it or the firmware. But the owner said the problem started immediately after an update. So, hardware issue is out of the question.

Since you’ve already followed the previous steps to no avail, then it’s time to give the phone a fresh start–reset it. But before you actually do that, make sure you backup all important data and files saved in the phone’s internal storage.

If you have a microSD card mounted, un-mount it as it may be corrupted during the process.

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.
