You are right.
Mine's actually an SSD drive, but got a black screen very eary on.
Lenovo fixed it remotely, but from what I remember, they made boot/os as an hdd partition.
I was relieved then to have had the problem fixed.
I think if I could redo the boot/os to ssd, my fan noise problem (mentioned in another thread) will be mitigated to a large extent.
Thing is am very reluctant to tinker now. It's just some kind of tedium i guess.
But will get to it one day. Hopefully soon.
Thanks for the insight, Czar. Actually reminded me of a real issue I need to get down to fixing.
