Hi all,
My work laptop seems to be having issues, is this normal:

It's 22 weeks old, 14 load cycles, health is 96%.

While using it for some light internet surfing, screen brightness low, fans running slow, no CD in or anything, my battery dies in about 1.5 hours. Would being connected as a network user have anything to do with this? Any ideas why?

Just wondering if it's worth IS looking at it. I have not done a full calibration yet, should I try that?

Thanks

I did that, nothing more than what I posted above.
Two things I see in there:

1) Skype is running and on your MBP it will force the use of the dedicated graphics which will reduce your battery life.
2) Flash is running on your Mac. Flash is, always has been, and always will be a battery killer.

Both of those are addressed by the tips in the Battery FAQ I posted, using gfxCardStatus and ClickToFlash.
