I currently use a Thinkpad T530 with Ubuntu 14.04 and TLP power management and it works great. I modded mine by replacing the 900P screen with a 1080P IPS screen and putting a bigger SSD (128GB vs 500GB). Highly recomended.

Specs:

Intel Core i5-3320M 2.6Ghz (Dual-Core) Intel HD4000 Integrated Graphics 8GB DDR3 RAM 500GB Samsung 840 Evo SSD 15.6" 1080p IPS Screen Blacklit keyboard

Price: About 1200€ after replacing the screen and SSD.

Forgot to tell that with TLP and a 9-cell battery I get about 7.5 hours of battery life using the ondemand profile.
