There's also the software/hardware integration side.
Power management on Macbooks is unbeatable in my experience, both Windows and Linux have really serious issues dealing with sleep and low power modes.
On the Lenovo side, the only one I'm still reasonably happy with is my Thinkpad, but it pales compared to a Macbook (Air, Pro or whatever).
I've been dealing with this recently. Linux won't hibernate if you have Secure Boot enabled, even if your swap is encrypted. So I either have to leave my laptop plugged in all the time or remember to shut it down before unplugging it so it doesn't completely drain its battery while sleeping.
That's why it works for you. Enable secure boot and you lose hibernate.

> The Linux kernel disables the possibility of hibernation when Secure Boot is in use because it cannot guarantee that the swap file is unchanged. "Unencrypted hibernation/suspend to swap are disallowed as the kernel image is saved to a medium that can then be accessed."
