I have a Toshiba Tecra M4. It works well under Fedora 16 except that
the fan is constantly on at high speed now. I don't know if it's
because of something I've loaded, a setting I've modified, etc.
If I add the option "acpi=off" to the boot command then the fan stays
at a reasonable rate.
Unfortunately this also slows down the CPU. My guess is that the CPU
speed information is contained within the ACPI interface.
Does anyone have experience with controlling the fan on a Toshiba
Tecra M4? I didn't always have this problem so it's either something I
changed or something that was changed by an update somewhere along the
way. Since I run the machine in various temperature environments and
with different loads I thought the problem was just the CPU running hot
but booting into a SLAX off USB showed the machine running normal - fan
running slow, occasional speed up, then back to slow.
Any help, pointers, etc appreciated.

List, good morning,
Experiencing difficulty in connecting from a netbook to a mobile phone
using Bluetooth PAN. And may I say - up front - before people waste
time they cannot spare, the netbooks are running F13 and F14; I do
realise these are out of date and I understand if folks choose not to
reply - if at all - in anything other than fairly general terms.
Objective is to connect to internet through a mobile phone using PAN
connection over Bluetooth. Bluetooth - generally - is working on both
netbooks, ie, under F13 and F14. Previously used Bluetooth in 'Dial
Up Networking' style of connection which has worked fine. (The phone
and Bluetooth works in PAN mode with this netbook (and with other
devices) using different OS, so the mobile side is - probably - ok.)
Network Manager sees the phone, and lists (on its menu) it as a device
that it could 'connect' to; everything seems to be 'paired' properly.
(During pairing, I selected the 'connect using PAN' checkbox - I
imagine this is 'how' Network Manager 'knows' that the device is
When I click the NM menu item to connect to this phone, one or two
seconds later the netbook reports - in a pop-up message - that the
network connection has been 'disconnected'. On the phone, the
Bluetooth icon changes from idle to 'connected', then a second or so
later reverts to idle, so some kind of communication attempt is being
made from the netbook to the phone, but the PAN connection is not
Honestly, the best advice I could hope for - if anyone can help - is
to advise where I could find a log just to see what's going on. I'm
pretty sure that once I have a clue from the log, there'll be various
posts in various places where people have encountered this before, and
solved it; initial searches haven't thrown anything up for me and I
need to search using more specific keywords, I think.
I'm also wondering whether some base configuration information is
missing from a file in /etc/bluetooth. On the F14 netbook, there are
only two conf files:
and neither contain entries describing the PAN service.
Thanks for reading this; I wouldn't expect anyone to recall what the
F13/F14 Bluetooth configurations were, but if anyone could point me
towards a log file that might show what didn't work, I'd be very grateful,
