> My Acer Aspire AS5536 laptop is now able to suspend/resume, after
having the BIOS update.

I saw it working with my own eyes but now it is NOT working any more...
long story short, after lots of trials and errors, I've now pin pointed
when it will not work and when it will --

I found that the suspend/resume will not work, with exactly the
previously reported symptom, when the HDMI cable is plugged in to my
laptop, that's enough for it not working. Whether I've logged into my
Xfce desktop, whether my Ubuntu 14.10 Utopic has recognized such HDMI
event, etc, etc, they won't matter. As long as the HDMI cable is plugged
in to my laptop, even it is just a freshly booted system without me
being logged into my X, the suspend/resume will not work.  I wll get the
repeating errors of `sda1` "soft reset failure", and HD light is on
forever. This is under the latest kernal.

However, if my  Ubuntu 14.10 Utopic is booted without the HDMI cable,
the suspend/resume will work just fine.

Hope this has dramatically marrowed down the scope of the problem.

Title:
  Ubuntu 14.10 Utopic suspend/resume not working for my Laptop

Status in linux package in Ubuntu:
  New

Bug description:
  The Ubuntu 14.10 Utopic suspend/resume is not working for my Laptop. I
  first tried with the Live CD, on failing that, and thinking that
  suspend might need some disk to write to for the suspend info, I did a
  HD installation. But still, suspend/resume is still not working.

  On second attempt (after HD installation), I switched to console and
  close my Laptop lid. It suspended well, as it has always been. On
  resume, I see the repeating errors of `sda1` "soft reset failure" (or
  something like that). Minutes later, I start to see all kinds of disk
  related errors, disk sector writing error, ext4 journal error, etc.

  I thus think the reason of `resume` not working is that the HD is not
  waken up.

  This is Acer Aspire AS5536, with XUbuntu 14.10 Utopic.

  Any more info that I can provide?

  Thanks
