I recently bought a computer, less then 2 months ago, brand new. As of today, it gave me a red x on my battery icon stating my computer might shut down unexpectedly and that i should consider replacing... I had this problem with my old computer, but after 2 years of so making me think that this isn't right... Both my computers were and are Acer, but the model of this one is Aspire 5750. I'm not sure weather my computer is under warranty, i will have to look into that but for now, i would like to try and figure this out before i have to spend a lot of money on a new battery, thanks!
