I did notice on this list, apparently Y480 model also not included for upgrade purpose.
But mine is without the SSD+ HDD configuration.
Actually i tried on those drivers available from the support website, but seems certain software are not compatible with windows 10.

I suspect it was due to network adapter which is auto configured during the installation process (clean install windows 10). May i know which network adapter you installed in your Y580? i tried to use the Windows 8 version but it can't work.

By the way, i'm having Broadcom 802.11n & Qualcomm Atheros AR8161 as displayed under my device manager.

Tried both ways, not working still 
Same like mine in that case, did you manually install your Broadcom driver? or windows 10 auto detect it?

Guys my y510p restart when I'm enabling SLI with nvidia control panel, anyone with this problem? Previously no problem. This issue arise this month.

I'm on Window 10 for a long time despite knowing they not supporting it. GG? 

I tried many version of nvidia driver, including the latest driver. The only one that is working is 355.80. So if any other y510p owner have this problem can try this version.
