Lenovo ThinkPad L470

Hardware Overview


NBC tells that L470 finds its place in the lower midfield: below the T series, but above the E series and highly recommends this low-priced business notebook. I've used it briefly on a business trip. It leaves okayish impression, but few things were of a constant annoyance:

Good things:

The best part is battery life, it's really impressive (10-12 hours); overall this laptop is not FreeBSD-friendly.

Boot-up and bare console behavior

Boots recent 12.0-CURRENT-r330450 more or less fine, but is unable to switch the screen to native resolution (with or without i915kms.ko modules loaded). Suspends, but does not resume properly (well, sometimes it kind of does, but with a blank screen). Often even cannot shutdown or reboot itself (hangs hard and requires full powercycling with the power button). X.org starts but I haven't tested it beyond that (e.g. hardware acceleration or behavior of OpenGL programs).


Apparently it fails to initialize properly:
