I did what you said, it eventually started to show the charging symbol on the screen, but then went blank and blinked red again. When I held the power on button, it's starting to power on, but I don't know if it is going to actually do it or not. :( It's still blinking red but has the power on

It says the battery is drained and now when I connect the charger it has the yellow light... but the battery was full before this so I'm confused.
