|Does it misbehave in any other way?|

Make sure the vents are clean because overheating can cause this. Are you using it on a flat surface, ironically using a laptop on your lap can block vents.
Better let us have the make and model number of your lappy - it might help.
Always pop back and let us know the outcome - thanks
