This is fun stuff, I put this together from another couple posts - people had been doing cool things like creating a new power profile, setting the options, and applying it - I couldn't make that work in the 15 minutes I wanted to spend on this - so here you go:
powercfg X -monitor-timeout-ac 90
powercfg X -monitor-timeout-dc 45
powercfg X -disk-timeout-ac 0
powercfg X -disk-timeout-dc 0
powercfg X -standby-timeout-ac 0
powercfg X -standby-timeout-dc 0
powercfg X -hibernate-timeout-ac 0
powercfg X -hibernate-timeout-dc 0
powercfg X -processor-throttle-ac none
powercfg X -processor-throttle-dc none
This will set the CURRENT power profile to the settings listed. Run as administrator..
