I have a similar problem on my laptop (Fujitsu=20 P2110). Using the acpi_video DPMS patch posted by jhb a while ago=20 helps out quite a lot and allows me to suspend for almost 24 hours=20 vs. about 9. This is still way less than Windows 2000 on the same=20 system which can be suspended for a week with just over 25% power=20 drain. I've tried with a stripped down kernel that is just enough to=20 boot eg. no USB, Firewire, network, etc.do_power_nodriver=3D3 and I=20 still have the same problem. You can try a stripped down kernel test, but I doubt it would solve=20 the problem. If anyone has anymore suggestions I'm sure there are=20 plenty more people that would like to hear them. =2D-=20 Anish Mistry --nextPart1374028.SaXNun9JZ2 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQBD7mQExqA5ziudZT0RAve2AJ9EVZq74va3FG+mGorUbnU4cY5GMgCfYh9W WOS7GuRkMRkLHyZK0b630gU= =T9ip -----END PGP SIGNATURE----- --nextPart1374028.SaXNun9JZ2--
