The high brightness display option on the updated T400 looks excellent and doesn?t take a huge bite out of your battery under normal activities. With most high brightness screens the power consumption is high even at lower brightness settings and what we found with the T400 is the impact on the battery is minimal at worst. On the 6-cell battery we managed 5 hours and 58 minutes of battery life, right on the mark with the previous T400 that used hybrid graphics. The updated keyboard support is my favorite change, knowing that Lenovo listened to feedback from users and improved the design. Overall, if you are in the market for a business notebook that is usable in direct sunlight, the T400 with the high nit screen option is the way to go.


  • Screen backlight makes me wonder where I put my sunglasses
  • Excellent battery life even with high brightness screen
  • Improved keyboard support
  • Excellent ThinkPad build quality


  • ThinkLight still needs some work
