You should be able to find the error blink codes on Toshiba's support site to tell you where the issue is.

I think it is your charger or battery going bad.

First, try a reset. Remove battery and from AC. Press and hold power on button for 30secs at least. Put back battery back and plug into AC then Power ON as normal.

If that does not help, try it with AC only (remove the battery) or the other way around.
