After using it for few days there's a few issue I've detected:

1) The LAN port
I always goes online by using LAN cable. After done with work I shut down as the normal way it is and go some places. Next I go a place with WiFi connection and I boot up my laptop. My laptop would not recognise any wireless nearby and it thinks that It still connect with the LAN Cable. I've to restart the laptop and boot up again and then it will recognise nearby WiFi. Is that normal?

2) Capslock Button
I try to press the capslock button during the windows interface. The small LED light would not turns on. Instead I've to let it loading a few program first, then it is ok. Have you guys encoutered this?

The problem is not serious but it does bother me. Thats not including the low brightness of the TN Panel as I've come from Lenovo previous flagship Y580. The screen is quite OK if compared to this one.
