Default Help please...

Just a simple question. I drained the battery of my tablet yesterday (the day I got it) and when I plugged it in, the led light flashes 2-3 times, and no battery charging icon would show up. When I reached for my tablet, the screen would randomly display the charging icon (note the tablet is off) how do I get the icon to display? Cause it's a pain not knowing what level of charge it is at....
