Hi all I have a strange issue with my new 13 inch Macbook Pro. Every so often (maybe once every 5 startups) the computer uses a huge amount of power after startup (30-35 watts according to Coconutbattery). The battery meter shows time until empty of 1-2 hours and the battery percentage drops rapidly. Once I restart it, it comes back on using 8-10 watts and shows time remaining of 6-7 hours. I don't think its purely a battery measurement issue... Last week it died whilst showing higher power use after about 2 hours. There are no applications opening on startup (that I can see) so am not sure what could be causing such rapid use. Any help much appreciated.
