[Acer Aspire V3-472G] Suspend
Understood Christopher. However, the bisection procedure that you
suggested me to do last time was not clear to me. Could you provide me
further indications about how to proceed?

Hello Christopher.
I had to replace the HD of my notebook as the previous one failed. I
replaced by a SSD, and it looks like the problem still persists. Should
I update the information of my hardware in order to continue the
debugging process?

I mean, the driver was indeed installed when I first reported the bug.
But when started to try the upstream kernels it was uninstalled. In the
recent test with 4.7.2 kernel the driver is no longer installed.
Thus, should I update the initial information of the bug?

Hello.
The driver is not actually installed. By the way, my problem is
happening at suspend rather than at resume.

Both the suspension test after using core and platform commands
reproduced the problem

Hello.
Tested with Kernel 4.6.2-040602-generic. The problem happens when
closing the laptop lid. As mentioned, the screen goes black, but disks
and fans keep working and power led does not go off.

Hi.
Tested with 4.7.0-040700rc2-generic. I tested the suspend even from the
login screen (Before logging in), and the third time I tried to suspend,
the screen goes black but disks and fans are still working and system
does not go to suspension. It requires a hard reset.
