Dell Inspirion 1300 doesn't wake up

[Chen Xu]

Dear list,

I searched but could not fine enough information. Here is my problem:
zzz or acpiconf -s 3 both seems working, i.e. put the laptop into
standby mode. However, it doesn't wake up -- open the lid or press on
the power button seem to have some disk activity, but nothing is on
the display.

Hardware: Dell 1300, everything works except sound card and resume.
FreeBSD: 6.2-prerelease

Anyone can point me a direction what to check?

Thanks,
-Chen
