Battery icon not working?

Hi everyone, i have a Toshiba laptop and im unsure if the battery indicator is working correctly. When the battery is nearly empty and plugged into the power, the battery indicator moves up and down about 4 or 5 times when it is first plugged in & then it stops. When i hover over the battery icon it says "**% available, plugged in, charging" but the battery indicator icon doesnt move up and down and it appears as though the battery is nearly empty, even though it says it is charging. However the battery still charges and after it has been plugged in for a while it reaches 100% charge but while it was charging the battery indicator icon was not moving constantly up & down. Does anyone know if this is correct?

On previous laptops i have had, the battery indicator icon always went up and down continuously until it reached 100% charge & once it was fully charged it would stop moving and the battery icon would be completely full.

Does anyone know if this is normal or is it a fault with my new laptop?

 

What's your complete model number?

If it's a newer model, make sure it has the latest software updates which can be found at the Toshiba support site [assuming your in the US]: Toshiba Support - Homepage
