[Bug 1552504] Re: clicking noise on acer 131t-c1yf


bhikkhu subhuti, thank you for reporting this and helping make Ubuntu

As per http://www.acer.com/ac/en/US/content/drivers an update to your
computer's buggy, insecure, and outdated BIOS is available (1.12). If
you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

For more on BIOS updates and linux, please see

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Also, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed.

If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

  clicking noise on acer 131t-c1yf

Status in linux package in Ubuntu:

Bug description:
  My machine is solid state.
  I updated the intel graphics driver
  I update a few days ago via ubuntu udpater

  There is a subtle clicking noise coming near from the usb port.  The machine is solid state and the ubuntu is running from the sd card  The noise happnes with usb live boot too.
  The mint 17 usb makes the noise too and then warns me that that the graphics gpu will not be used and then the clicking stops.
  Lubuntu installed on top of ubuntu still makes the noise.
  Lubuntu live usb does NOT make the noise.
  Windows 10 does not make the noise.

  I suspect compiz, but ultimately I think it is a kernal problem.
  I suspect this is a CherryView Bug.

  This bug has been reported on ubuntu forums and ask ubuntu and no responses.
  I will be switching to Lubuntu in a few days unless I hear back from you.  I am technical and willing to help.
