Lenovo ThinkPad T400s Multi-Touch Notebook
Our T400s Multi-Touch arrived with a standard, removable 6-cell battery. Lenovo claims that the battery is good for up to 5.5 hours of use, but we found that claim to be dubious. In fact, we think that estimation is nothing short of wrong. While using BatteryEater Pro, which does a great job of simulating a "real-world" work environment, we only squeezed out 2 hours and 37 minutes of usage.

Even with Wi-Fi disabled and the screen brightness dimmed to a minimum, we could only imagine getting another hour or so of life, and we honestly cannot fathom a situation in which you could see 5.5 hours of use; maybe if you were doing nothing at all on the computer.

This seems like yet another case
where the PC manufacturer is making numbers up based on in-house
testing; all the user is told to expect is "5.5 hours," yet we've no
idea what kind of circumstances surrounded that figure.
