My 9220 restarts and switch off itself and service center can't fix it.

Question

I'm in need of help. My BB frequently turns off by itself, even if there are no applications running. I tried to restart it by pressing the power button, but that never worked. I had to hard restart it by taking off the battery and then putting it back on again. I need to do this around 2 or 3 times (only once if i'm lucky) to get it to turn back on. The frustrating part is when it shuts itself down again only a couple minutes after I had managed to turn it on again.
I took it to service center and there they collected it but since last 1.5 Months i am trying to get my phone but they say that we didn't fixed it.
Please help me.

Without the device in your hands, it's rather useless to have advice since you cannot carry it out. But, since you desire it, here are some things you can try. I do not know which, if any, will work for your situation.
I recommend that you attempt to boot into Safe Mode:

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.
If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.
But if the behavior continues in Safe Mode, then you may need to consider more drastic actions -- WIPE, OS Reload, BBSAK Wipe/Reload, and the "Bare Bones" OS Reload Process. To prepare, you should be sure that you have a full backup to your PC...please review the Backup link in my auto-sig on this post for instructions.

On the chance that your battery may be causal, 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):
With the battery inside, connect your BB to the wall charger
Leave it alone for 2 hours, no matter what the LED or the display does
Remove the battery
Wait 15 minutes
Insert the battery
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:
Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
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!
