My tablet won't turn on

[Blackh]

When i left my house my tablet was fine when i got back it was off. I tried turning it back on but it only went to the Dell logo, a dulled dark screen . then after it just turns back on and does the same thing over and over again. When i plug it in it
Just says "no command" then it starts turning off and on again. It doesn't even show that its charging. ( on the no command part it shows the andriod logo robot laying down. Above it is a red triangle with a exclamation mark with the words command)

Did you perchance install any new apps (or updates to apps) just before this happened? I ask because it sounds like something is preventing it from starting/working.

If not, then it may not actually be charging. If there is any problems with the charger cord, charger port, or the battery, then they may need to be fixed and/or replaced.

If none of this does the job, then you may have to consider doing a "Hard Reset" which will remove all your data, so only use as a last resort.

Lastly, if you don't want to do the "Hard Reset" or if it and all the other things don't work, you may need to take it to a local tech and see if it repairable or not.
