Lenovo ThinkPad 25 Anniversary Edition Review: Retro Style, Modern Performance
ThinkPad 25 Anniversary Edition: Battery Life, Thermals, and Acoustics
The first test up is our custom 1080p video loop test. This benchmark plays a 1080p HD video at 16Kbps bit rate and loops the video constantly with a 1-minute break in between. A timer log file records the up-time in minutes and saves it when the machine inevitably turns off from lack of battery power. It's a less strenuous test than BE Pro.
A Note On Thermals And Acoustics
One of the most annoying things for many users, with an ultrabook that packs in lots of performance hardware, is noise. Thankfully, during the benchmarking of the ThinkPad 25 AE the machine remained impressively quiet. Quiet to the point that we had to repeatedly look over just to see if it was still running. There was only moderate fan noise in our heaviest test conditions. It's obviously a machine built with an ample thermal solution and footprint to support it.
This ultrabook also stayed impressively cool. The only warm spot was in roughly the center of the bottom of the machine and it was certainly not so hot as to make a user uncomfortable if you have the machine on your lap. A silent and cool machine is a big deal in certain environments and use cases, and the ThinkPad 25 Anniversary Edition delivers in full here.
