Since the recent updates, my SB (i5/8/128) is working very well. The only real issue that remains (other than the odd freeze) is that when I open the lid in the morning, sometimes (not always) the book will not wake from sleep. The power is on, because I can detach the keyboard and reattach, and the keys light up, but the screen stays completely black. Nothing will wake the computer - I have to power down by holding the power key and then reboot. Event viewer only shows that the previous shutdown was unexpected. Any ideas?
