R-series battery life (is it shorter than for T-series?)

[superiorlobe]

I can but either an R-series notebook or a T-series notebook through my school at a discount. It appears that the T-series uses centrino processors and gets a much longer battery life. Is this true? Can anyone make any certain pronouncements on the battery life a mid-level R-series vs. a mid-level T-series?

Thanks.

I should first note that Centrino is not a processor. It is a platform for notebooks consisting of the Pentium M Processor, 855 series chipset, and Pro Wireless WiFi mPCI card.

You can look at all of IBM's ThinkPad offerings here:

IBM offers the Centrino platform in both R and T series machines, as well as machines that use just the Pentium M and 855 chipset and non-Intel wireless cards.

I know some versions of the R40 use Pentium 4 or Celeron processors, but these are pretty much on their way out.

Identical.

Hey,

Can you post what models you are looking at. I was taking a look through the psref sheets and noticed that some r40's have 8 cell batteries and the t40's have 6 cell batteries.

These are both Pentium- M machines. Only things that I could see that could have an affect on the battery is possible the wireless card that comes with it..maybe also the video card. I know some of the R series have 1394, maybe they count that.
