you guys should be ashamed you rate these new Lenovo laptops this high without a powerbridge. You basically endorse it at this point. Goodbye to modularity and hello to inflated rigid hardware.
The T590 stays on longer than a T580 with 105Wh, the giant cylinder battery, so my first impression is that your argument is bunk.
However, I agree that we should encourage modularity--although, I seriously wonder why this newer internal battery outlasts one nearly twice the capacity.
For one thing, THE MATH DOES NOT ADD UP between the power consumption and battery runtime. I calculate the expected runtime using the "load average" power consumption and battery capacities, and compare to the actual runtimes:
T580 calculated runtime: ((105 W*hr) / 58.3 W) * 60 min/hr =
108 minutesT580 actual runtime:
158 minutesT590 calculated runtime: ((57 W*hr) / 61.6 W) * 60 min/hr =
56 minutesT590 actual runtime:
209 minutes !!
At some point we just have to question these measurements because they are absolutely contradictory.
At the same time I believe the "actual" runtimes because a stopwatch is more foolproof than a power meter, and so I still think that as long as the runtimes on the T590's internal battery are longer than the T580 with the largest possible external battery pack that it is fine to say goodbye to the power bridge.
