Studio 1557-battery

otto1357 · 03-02-2010, 11:52 AM

I recently got a studio 1557 with a 9 cell upgrade. I was told that the aprox usage would be 5.5 hrs. The other day I used it for the first time and got less than 3.5hrs.

I wondered what other peoples experience is.

Is there a utility to see what batter you have in the machine? It does not appear in the system hardware.

I'd just pop the battery off and check the Capacity value that should/will be printed on the bottom. If it's ~56Wh then it's a 6-cell, and ~85Wh it's a 9. I'm guessing a bit at the values - but my old 9-cell sat in front of me is 85Wh (it now lasts about 20 mins...

)

I would suggest that battery life claims by manufacturers are alwys hopelessly optimistic. It assumes your not actually doing anything that uses any power.

I've recently bought a Studio17 with a 6-cell battery. I get around 2 hours of wireless internet, so 3.5 hours from a 9 cell would be about right.

I'll have a look at checking for battery info tonight, are you on Vista or 7?
