Hi , ive recently bought a laptop and it is always running at 50-112% of the cpu usage usually telling me java is using 50%+,sometimes even 90% of my cpu on things like runescape. The clock speed is also rising to 3.2ghz instead of the maximum speed it says to be 2.5ghz. Is this normal or is it something I should be worried about?
