Bold 9790 keeps restarting for no reason?

Hi,

I have a BB 9790. The first weeks when I bought it, it still works perfect. But it's been a year and my Blackberry keeps restarting for no reason. Last night i plugged in the charger and leave it charging through the night. And at the morning when I turned it on, the battery symbol shows that it's on full state. But when i tried to turn on wifi, the blackberry died and there's a red light in the top of the BB. I thought that after a restart it'll be fine, but actually, no. After that I tried to make a call. Then it happens again. Up until 3 times. And for the third time, the battery is finished. It says "battery drained. Shutting down handled". I haven't even used it for like 10 minutes. It's dead in 5 minutes. What is wrong with the newer BB? Can someone get me a fix?

Re: Bold 9790 keeps restarting for no reason?

Hello!

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

  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 an 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. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.

Good luck and let us know!
