So I returned my first sp3 i3 because of the horrid yellow streak. Everything was perfect with that machine but that yellow haze. The battery lasted a lot longer than my replacement which was brand new because I returned it for another one. My new i3 does not go into connected standby and as a result my standby battery life is taken a hit. I can't figure out why. I set the replacement one up identical to previous sp3. Any ideas?
