I'm using a laptop guiminer setup and I am getting a 3.7 MHashes/s rate. Is this accurate, as I've seen a max of Hrates in the high KHases per sec for GPUs, so I am doubting the accuracy of this value. Attaching the screenshot

Those higher rates are with high-end desktop ATI cards. GPU mining is on its way out anyway; probably best to not mine and give your laptop some rest.
