Bold 9900 Won't Turn On

Recently, I've been experiencing trouble with my device. 

I'm currently with Bell, and my warranty has expired.


The problem:


My Blackberry Bold 9900 is not turning on.




  • A battery pull has not fixed my problem.
  • I tried using another 9900 battery, however it did not work.
  • My battery does not work on other 9900 devices.
  • There are no signs of moisture, nor has there been contact with water.
  • The LED light doesn't show, nor does anything on the screen.

Are there any solutions to my problem?

Re: Bold 9900 Won't Turn On

Hi and Welcome to the Community!


I cannot quite tell if you have done exactly these steps, especially anything related to "known good"...hence, 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 (you may need to do the above 4h15m process, if your battery has gone completely flat)

The results of this will indicate if it's your BB or your battery that has the problem. It may also be both...that would be unusual, but not outside the realm of possibility.

Good luck and let us know!
