Laptop keeps going into standby

[coudert at clipper.ens.fr]

Hello,

I installed FC2 on my 3-years old laptop to replace my RedHat 9. The
only problem I do experience is that the laptop keeps going into standby
mode, every 2 minutes (approximately, 2 min +/- 10 seconds). And that
does not depend on what I am doing with it (even massive up2date +
Mozilla browsing + SSH connexions). I must say that my laptop is always
on a AC power, and that the problem did not appear with RH9, nor with my
current DOS installation or WinXP.

The problem is the same whether apmd is running or not. When I stop
apmd, there is no log of the standby anywhere. When it is running,
/var/log/messages shows the following:

In either case (apmd running or not), there is nothing relevent in dmesg
output, except from:

eth0: no IPv6 routers present


I hope you can help me with a solution or means to investigate the
issue. Please Cc: your answers to me as I'm not suscriber.

Thanks,
