FreeBSD laptop support is really specific and limited. I got FreeBSD-11 working perfectly on a Carbon X1 1st gen ... but the motherboard on it is going out and it likes to reboot randomly now (checked the ram, SSD and tried updating the BIOS .. BIOS update fails with a beep code whose only forum response on Lenovo's website is "return for warranty." :-/)
If you want FreeBSD on a laptop, check their wiki/list. There is a small subset with full suspend/resume support right now.
