Charging problem topic

Well, last night I was using my HTC One until the battery went to 1%, I plugged the device but it turned off anyway. I plugged the carger once again with the phone already off due to no battery remaining and it turned the screen on with the ilustration of a battery indicating that is charging, then the phones screen went off, along with the LED a like 3 times, and now the screen is off and the LED just keeps turning on and off like once a second.
What happened to my phone? Is there a way to fix it?
Please help!
