Minimum requirements for this?

Hey guys, so im finally back on the old train again after many years of not playing old school RS.

Been playing it for a week now but my butt gets really tired sitting up right on my pc for long hours at a time.

Decided to go ahead and invest in a laptop (Lenovo thinkpad t500)

After purchasing it however, i forgot that there are probably system requirements for this game. The laptop runs the following:

"Windows 7 home premium 32 bit installed.

Core 2 duo 2.40GHz

2GB Ram "

can i actually run this game with those specs?

I know it sounds silly, but im just worried that i bought the wrong laptop

Thanks
