Bug ID: 85181
Summary: SSD is hotter when starting on battery than starting
on AC source
Product: ACPI
Version: 2.5
Kernel Version: 3.13.0-36-generic
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Battery
Assignee: [email protected]
Reporter: [email protected]
Regression: No
Hi,
I'm using Xubuntu 14.04 with TLP on a Clevo W65 and with a Crucial 120G SSD.
When I start on AC power source, the mean value of the temperature of the SSD
is around 40°C/45°C. If I remove the AC source (keeping the battery on place),
the mean temperature stay stable.
If I start the computer without the AC source, the mean temperature is
50°C/55°C, and if I put the AC the temperature stay around 50°C/55°C.
The strange thing is that the source present on starting change the behavior
and, with start on battery, the heating is more important.
I'm using TLP to manage the power consumption and I put the same setting on AC
and on battery (to reduce the heating of SSD). That's why when I change the
source, I have not differences of temperature.
Are there any process which are launch on battery (and not on AC) and
sollicitate the SSD ?
Thanks
PS: I made a bug report on launchpad, but there no evolution, here the link:
