Hi,

I have a Sp4 i7 and lately it has been shutting down at about 30% battery without warning. I have tried doing a battery rundown and charging it back up in an attempt to recalibrate it but have had no luck. I can't seem to be able to configure the battery to go to a full critical level rundown like they suggest that you do because those options are disabled in the advanced power plan settings.

Any suggestions? Also do you think that's something that warranty would cover worse case scenario?
