Hello!
Because other operating systems have no issues? Even Windows works with some workarounds, so I dont see how your point is valid.
Could be a faulty RAM and/or NVME. I had the same caused by faulty hardware.
Could be a lot of things. If Linux is also affected, maybe a faulty motherboard.
If not, a broken Windows install, missing drivers, bad configuration etc. Could be at fault.
So you have a portable windows setup on your lenovo carbon? Else you compare apples with oranges.
Yes, the Framework laptop has a few early adapter issues. But most are not caused by the Framework design or firmware.
