problem with APM on a Vaio FX501

[shoegoo3 <shoegoo3@free.fr>]

I have got a problem on my Vaio FX501, maybe you can help me.

APM stuff is not working fine: the battery has a very short life-time when 
I use my laptop unplugged.
apm is here and working (I can get informations about the battery) but it 
seems like my cpu fan as my harddrive are always working : so it uses a lot 
of power.

I have kernel support and I installed apmd and apm packages(I haven't done 
much more configuration).

Do you have an idea for me to solve this problem?

Thanks
