This is usually a problem that can easily be solved if there is no secondary cause of the problem coming from within the device.
All you have to do is to make sure that you charge the device vigorously for at least before trying to switch it on again. Continuous trial would only result in an even worse condition where the battery may die below the expected limit and this would cause serious problem.
On the other hand, if the battery has been inside for a very long time without usage, it can cause the battery to automatically run so flat that it may refuse to charge. In this case you would have to replace the battery with a new one.
