Lenovo tab m8 fhd unable to sleep

2021-01-27, 19:19 PM

I have just upgraded this tablet to Android 10 and now it will not sleep unless manually push the power button. I have tried various sleep time but no effect. It drains battery if left on. Anyone seen this and has a a fix? Thanks.

Welcome to the Community Forums @bunts1!

 

Glad to have you here!

 

Just to ask, are there any app(s) that are running in the background while the Tab M8 FHD is in idle/standby mode?

 

If yes, close them out first then test it again.

 

Also, perform a power drain to the device as well even if you've just updated it to Android 10.

Press and hold the Power button for 5 seconds then turn it off.

Turn it back on again then check if it will now go into Sleep mode afterwards.

 

You may also check this previous post for other troubleshooting steps.

 

Update us how it goes.

 

Thanks,

Yes I have tried both the suggestions. 

 

1. I usually close all apps.

2. I have power down the tablet after it was updated. 

 

I leave it on stand after using and closing all apps (swipe up to close) and it remains on. 

 

Thanks.

Thanks for the update @bunts1!

 

If none of those steps worked, it would be advisable to perform a factory reset to the Tab M8 itself for all of it settings to be set back to defaults.

Please take note that this step will erase all user data, make sure to back them up first so that you can restore/use it again.

 

Once done, test if the Tab M8 will now go to Sleep mode or lock its screen automatically after the timer runs out.

 

Let us know what will happen.


Thanks,
