Hi and Welcome to the Community!

Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain connected to a known-good wall charger (not PC USB):

  1. With the battery inside, connect your BB to the wall charger
  2. Leave it alone for 2 hours, no matter what the LED or the display does
  3. Remove the battery
  4. Wait 15 minutes
  5. Insert the battery
  6. Wait another 2 hours, no matter what the LED or the display does

This has been known to "kick start" some BBs.




It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:

  1. Obtain a known good and already fully charged additional battery...use it in your BB and see what happens
  2. Obtain access to a known good and identical BB...use your battery in it and see what happens

The results of this will indicate if it's your BB or your battery that has the problem.

Good luck and let us know!

thank you very much for your help sdgardne..appreciated it so much..i have tried what you told me to do but still the same...however i've sent my BB today to an authorized Blackberry Service Center and after a brief checks, they told me that maybe the Software has crashed or maybe the Motherboard. if the software crashed then it would be a small problem but if the motherboard had crashed, then my pocket will be empty...by the way, still waiting for them to get back to me....cross my fingers...hope it won't be so bad...by the way...thanks a lot for your help...

Re: Did you try removing the battery and inserting it back ag...

Hi,

I am facing a similar problem with my BB 9790. The phone switches off by itself (even when the battery shows as fully charged) and then switches back on (on its own) and a few minutes later switches off - it keeps doing that. The only way it doesn't switch off is if its connected to a charger.

I don't know what to do!! Please help!

Hi and Welcome to the Community!

 

You report that you tried everything, then say you only did 50% of the tests listed in the referenced post (4). Please try the other 50% of what that post recommends (the battery swap).

 

Good luck and let us know!
