Dear Ubuntu people,
I'm using Ubuntu 10.04, but I had the same problem with 9.10. Both of these
systems were installed on a partition.
Previously, I used Ubuntu 9.04 without problem, but this was NOT installed on a
partition.
My laptop came with Windows Vista pre-installed: I do NOT experience this
problem when running Vista.
(1) After a few minutes from a "cold" start, my laptop overheats and
automatically shuts down. The "Core Temperature Sensor" indicates that it
shuts down at 100 deg C. Other temperature sensors do not report any
abnormalities.
(2) If I re-boot IMMEDIATELY, the cooling fan starts and the Core temp quickly
drops to approx 45 deg C, and I can run my laptop all day without any problems.
(3) If I fail to re-boot immediately, or if I restart my computer before the
sensor indicates at least 95 deg C, the computer will again suddenly shut down
within only a few minutes due to overheating.
My laptop is an Acer Aspire 5315, but I've seen lots of posts on various
forums. Toshiba computers seem also prone to this problem when running
Ubuntu - and I have noted that Acer computers use Toshiba fans.
Everything I've read follows the same trend:
(a) it seems that, when everything is cold or only warm, Ubuntu fails to
instruct the fan to run, so it doesn't.
(b) if the computer is already hot when it's switched on, the fan works
perfectly. Presumably the computer has a separate thermostat to control this,
since we know that Ubuntu isn't switching it on.
I'm sure this has been reported millions of times before. It is a major
problem, and certainly one which prevents people recommending Ubuntu to
others.
Thanks & regards,
Tony
