This is a Gigabyte AERO 14 laptop (http://www.gigabyte.com.au/products/product-page.aspx?pid=5902#kf)

When laptop goes into hibernate mode, the trackpad will no longer work. Rebooting will not make the trackpad work again.
The only work around I've found so far is to reboot into windows and then reboot into ubuntu.

It is similar to bug 1490130; however here it's with hibernating and can't be recovered with rebooting (additionally, the kernel patch provided there doesn't work)
Suspend works just fine.

So after hibernating, the Eland trackpad no longer appears into the list.

Also tried with 4.7.3 kernel-ppa and it makes no difference.
