    I've disabled SpeedStep, took out the battery, and changed power options to high performance yet here it is running at a measly 800mhz according to cpu-z. Even with an SSD everything feels really sluggish on the 15 because of it. What's going on here?

    On what performance plan is your laptop?

    Well the CPU only steps up if you need it to...that said disabling speed step should get it running at the normal speed. Did you disable turbo-boost?

    @synce and madmattd,

    For laptops, disabling SpeedStep in my experience led to a constant 'downclocked' CPU state, turn it back on. The CPU will not be used fully unless it is under load.

    @madmattd,

    As far as I know, one cannot disable turbo mode unless through a non-BIOS means.

    I know in Dell BIOS disabling Intel Speed Step will lock CPU at the lowest state. You are probably experience horrible throttling issues. Are you on the correct wattage power adapter?

    I really do think synce disabled SpeedStep from the get go. I don't know about him/her but coming from a desktop years ago I made the same mistake since it was second nature to disable SpeedStep for OCing purposes LOL.

    @zjacobss,

    That was the non-BIOS method I was referring to, thanks for posting that.
