The last time my ThinkPad 755C was in the way and shuffled around as part of re-arranging, it still booted up.

The only other device I've owned which might have that sort of longevity is my Fujitsu Stylistic ST-4110 (which I quite miss for its transflective display).

Really wish the Lenovo Yogabook 9i was in the ThinkPad line and that it had a Wacom EMR stylus....
