I've never had a Lenovo before but I recently picked one up for great price at Office Depot. Man, the screen beau-ti-ful and it runs like a trooper. Happy owner here. :) That’s some pretty cool battery life!

I'm happy to know there is a device that is capable of giving ab battery life of 8-10 hours. There are only few devices that can give long batter span. Another device i knew is from Samsung. It could last up to 11 hours. Long batter span is really important for me because I often travels with a laptop always with me. I’m interested to see this model of Lenovo.

Even though you won't get that full 15 hours, 10 hours is still a pretty nice battery life. Holy crap. Even though you won’t get that full 15 hours, 10 hours is still a pretty nice battery life.

Hope that helps - Spencer Hey Orlando,

Here’s my configuration:

Intel SL9400 CPU @ 1.86GHz
160GB 5400rpm HDD
4GB DDR3 RAM
1400×900 LED screen
Bluetooth
Intel 5300 WiFi
Fingerprint
5-in-1 card reader
(with modem)
Windows 7 Professional 64-bit

A few thing that have helped my battery life:

Installed all the latest Win 7 drivers from Lenovo: http://www-307.ibm.com/pc/support/site.wss/MIGR-70656.html (in particular the power management driver)

Manually configured the “battery settings” for “power source optimized” power profile:

Max CPU speed is Low
CPU deeper sleep enabled
optimize fan control to balance all parameters
display brightness fairly low

Dim display after 1 minute
Stop HDD rotation after 3 minutes
standby after 10 minutes

PCI express link state power maximum power savings
desktop background slideshow paused
system cooling passive

It looks like you have Windows 7. Would you mind sharing your configuration, please? I'm struggling to get 7 hours on my 9-cell and am looking for insight from others. This is my sig line from notebookreviews.com - - Lenovo X200s (1.2Ghz|500GB,7200rpm|4GB|1400x900 LED|BT|Intel 5100 Wifi|FingerPrint|5-in-1 card reader w/modem|Windows 7 Ult) Hope to hear from you.
