View Full Version : [all variants] Laptop owners: Potential bug causes excessive HD temp

January 19th, 2009, 12:04 AM
Howdy folks,

This is a heads up/request for feedback concerning bug #318346 (https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/318346).

To provide bug assistance:
- Have an Intrepid system patched with acpi-support_0.114-0intrepid2.
- Use hddtemp or smartctl to obtain hard drive temperatures. GNOME users may also want to install sensors-applet.
- Switch between AC and battery power and monitor HD temp for several (30+) minutes on each.

- If no change in HD temp is observed, you're in the clear!

- If you experience the same issue as described in the bug report, downgrade to acpi-support_0.114 (http://packages.ubuntu.com/intrepid/acpi-support) and shutdown the system for a few moments to allow HD temp to fall.
- Boot the system and allow the HD temp to rise.
- If on AC power the HD temp maxes out lower than when acpi-support_0.114-0intrepid2 was installed, please submit the relevant info (https://wiki.ubuntu.com/DebuggingACPI#Filing%20a%20Bug%20Report) to the bug report.
- It may also be a good idea to re-upgrade to acpi-support_0.114-0intrepid2 to see if HD temp increases again.

I hope this bugs affects a small number of laptops (e.g. my HP dv6500), but I feel it should be brought to everyone's attention in case a significant number of laptop hard drives are being subjected to potentially damaging temperatures.
