Blackberry Bold 9900 won't turn on for no apparent reason.

I had my blackberry on charge upstairs as it had been all night (the nightly charge is what I have done since I have had the phone since november 2011). I checked my messages and everything else at around 9 o'clock. I went upstairs to check on my phone again to see if I had any texts and find that the phone was blank when I touched the buttons. This had sometimes happened in the past; the phone wouldn't respond to the buttons being pressed so I would press a few repeatedly asand then it would eventually realise and everything would be normal. I then realised it looked as if it wasn't going to respond so I took it off the charger and took out the battery and then replaced it and then held down the power button. Still no response. I tried again and nothing happened. I then thought that perhaps the charger had not charged the phone so went to another plug and repeated the mentioned steps. Nothing. I thought I would then connect it to my laptop and see if I get a response from the blackberry as it would be connected by usb to the laptop. Still nothing. I;ve taken out my memory card and tried to restart it a couple of times but still nothing. 


I desperately need some help as this phone is very important to me right now. 

Any advice accepted.

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!
