Hi, Same thing happens to me. Brightness is down to zero not only at boot but also after screen goes to sleep and it's waken up by pressing a key or after wake up from standby.
I'm on Thinkpad X200s and use 8.10 64bit. I only installed it about three weeks ago and there was no problem with brightness at the beginning and only started happening after I installed updates roughly two weeks ago.
