For the last month my now 4 month old Alienware M18xR2 only lasts 90 minutes on a fully charged battery. I am only doing general internet browsing and using MS Office 2007. I do have the twin 680M video cards active but doubt this will be a huge factor as I'm not doing any 3D usage.
Surely the battery should last more than 3 months.
When I first got this laptop I was getting over 4 hours usage.
Any suggestions as to how I can fix this or do I have a faulty battery?
cheers
