Re: BOLD 9790 not working

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!

Re: BOLD 9790 not working

Since don't work for the Service Center nor for BlackBerry, I have no idea what the service center will or will not do, nor do I know what the exact terms of your warranty coverage are.

Good luck!

Re: BOLD 9790 not working

Sir, I did it twice. 2 hour and 15 mins and then 2 hours without taking out the charger.

But it still doesn't work and both phone and battery are fine.

Pls suggest what to do?

Re: BOLD 9790 not working

Did you do the 2nd part of what I suggested? Find someone with an identical BB with no problems, and trade batteries...see what happens on each?
