Hi!

I searched the X60/X60s notebooks and find some notebooks working more than 3 hours from the 4 cell battery.

Is it an improvement in the technology, or it has bigger capacity accumulators (prismatic->cilindric is 2000->2600mAh, which is 33% improvement in battery capacity)?
I dont believe that T2500 procesor equipped notebook consumes less power than L2300....and working 4.1h from the same battery as mine with Vista. I managed to work 5 hour from 8 cell battery with Vista....and I think everybody ran this bigger power consumption issue under Vista...

Core Duo T2500, 4.1h (Vista Business)

T7200, 3.6h (Vista business)(this cant be! Vista runs about 5 hour from 8 cell battery)

L7400, 8.4h (8cell) (Vista Business)
http://www5.pc.ibm.com/cr/products.nsf/ ... enDocument

How can this be?
If it is real, I need the power manager settings from that Vista Business.... because it works more than my Xp with notebook hardware control (maximum battery settings, minimum speed) :)

Is there anybody here with X60/s with Vista Business from Lenovo?

Good question i read some reviews on the net and they seem to be able to squeeze so much more power out of the x60 then i can. Some setting they must be using may be the reason.

Perhaps they used brand new batteries and yours is older. Also, whether the wireless card is on and the brightness of the display can make a huge difference.

My thinkpad x60s is brand new...

There is 3 cycle in my battery. It is 105% factory default (30,3Wh).
I use the TP since 15:20 and now 17:30, and it seems to have 30 minutes left (20%).
This is 2:40. Brightness is on 4, wireless on, internet browsing....

I think 4,1h is impossible with Vista from the same battery.
I installed Vista on my last x60 in january, and I installed all the driver from the lenovo site. The maximum time was 5 hour from 8 cell battery. The 8 cell battery is about 75wh. So the Vista consumed 15w.

The same system lasted about 7 hour under windows Xp. So the Xp consumed 10.7w.

So:
1: the power management driver is better than XP. It is possible with 7w power consumption.
2: they used 60Wh battery :)

I cant beliewe the system with T2500 consumes only 7w!
