Re: Fan control ?

Hi Rogério
You ask ... correctly .. whether I really do net those services,,, and yes! there are a few that can be stopped ! But the intention of using an old Powerbook was ..... as this _is_ a mail-server, web-server and file-server..... that it would be quiet!

I also have a "Mystic" (dual G4 450 Mhz box).. that might be more suited.. in particular as the fan is on all the time...
but not so noisy as compared to the TiBook

But definitely.... will try the various suggestions.. when I am back ...... _close_ to the TiBook! ;-)

The best thing is to isolate the unneeded parts all at once and go on
turning them on one by one.

Also, it would be useful if you could drop into single user mode to get
rid of all those Desktop Environment crap.

Do you need appletalk?

I'm not sure if parport on such a notebook is needed.

Do you need autofs4?

Unfortunately, the ondemand and conservative drivers most probably won't
work with your computer (it may complain about too high latency to
switch speeds---heck it even does that on my Pentium D 805).

Which filesystems are you using? Ext2? Ext3? You can drop the unneeded

I'm not really sure about lm75 on an Apple Mac.

Are you using Firewire for the moment?

dm_mirror              20608  0

Are you using any kind of redundancy (RAID) on your powerbook?

50,1% ( 53,9)       <interrupt> : 1    Level     VIA-PMU
7,8% (  8,4)       <interrupt> : 1    Level     ide1

You seem to have many access to the disk. Perhaps, you could track down
what is using the disc with:

echo 1 > /proc/sys/vm/block_dump

(Warning, this may generate copious amounts of output!)

1,4% (  1,5)            mysqld : schedule_timeout (process_timeout)

Do you need an SQL server on your notebook?

0,9% (  1,0)           apache2 : schedule_timeout (process_timeout)

A webserver?

A mailserver?

A spam classifier?

A DAAP server?

An anti-virus checker?

Those suggestions from powertop are very good measures to take if you
are chasing something that you don't really understand.

Anyway, I suggest that you think about the points that I listed above
(after all, you know your needs). There's no need to justify your uses.
I'm just bringing them to your attention.

OTOH, seeing if the fan is turned on even when you remove some modules
and in single user mode would help a lot (as root, run: "telinit 1").
Running powertop while in single user mode would also help.
