Won't turn on

The battery ran out of power because the alternator is not charging it.
Have the alternator output tested and take a look at the fuses.

You need to replace your old battery. Don't over charged your battery. If you are using your laptop in your house it is better not to use it with battery. Just use the power adaptor/supply only. Then make sure you will drain the battery let say once a week. =)

Ifthe rechargeable battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

If your iPhone's battery runs very far down, the iPhone won't turn on. That's because it's using its remaining battery life to preserve your data and settings.So, your iPhone could be refusing to turn on because its battery doesn't have enough juice. In that case, plug your iPhone into a wall charger or into your computer (plug it directly into the computer; some USB ports on keyboards don't have enough power to charge iPhones). Let it sit for 10-20 minutes. If it was low on battery and needed a charge, when it's got enough juice to power the screen, it will turn on and show you its charging status, starting with the red battery icon.During this process, you may also want to make sure there's no lint packed into your cable or the iPhone's dock connector. This isn't a hugely common problem, but a lot of pocket lint could interfere with the iPhone getting a charge.

Does the phone come on while plugged in? To me it seems that the battery is dead. If you feel the battery is fine then you must visit the BB Service Center.

Try somebody else's battery, if the problem persists, it's most likely a logic board issue. There are blackberry repair websites that show you how to do the replacement yourself, otherwise here is a service that can repair any Blackberry Bold, Storm, Pearl, Curve, 8800 for screen, lenses,
track balls, usb ports, waterdamage etc.
The website is: Blackberry Repair

The icon for the battery should change when the charger is plugged in.

If the Icon doesn't change when the charger is plugged in then it is probably the charger.

If the Icon does indicate an external power source but the battery doesn't charge then your battery needs to be replaced

ok so what u basically do is just keep the charger in the usb port. then take the battery out then plug it back in. this totally works!

Remove the back of the phone. Pop out the battery. let it sit for about 10 minutes. Replace the Battery & the back cover of the phone. If the phone starts up, then let it start and immediately plug in the charger and let it charge for 1/2 hour before you touch it again.
If the phone does not start up then do not try to start it just immediately plug in the charger and let it charge for 1/2 hour before you touch it again.

It works for my Blackberry Curve 8310...

sounds like a dead battery. Plug the origional charger into it and the front led (below the flash) should flash red. If the red led in the back of the camera flashes or stays lit, then you have the wrong charger plugged in. (the camera won't power up if the back red/green led is on when plugged in)
