Re: [gentoo-user] Power Drain during Suspend to Disk
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, i just wanted to finish this as I found a solution and want it get archived in the list archive. If you experience power drain during hibernation check cat /sys/power/disk On my machine it was set to platform, wich means the bios takes care of everything. After installing a new harddrive into my machine this did not work anymore and there was a small but noticable power drain during hibernation. Setting it to shutdown (echo shutdown /sys/power/disk ) solved the problem for me.

[gentoo-user] Power Drain during Suspend to Disk
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi all for some time now, maybe since I updated to Kernel 2.6.23, I experience power drain during suspend to disk (yes, you read correctly DISK). I'm using an IBM Thinkpad X30 and the problem is recent. I assume that its some kernel option keeping the ethernet alive for wake on lan, or something like that. Has anyone experienced this, and/or knows kernel options that can be responsible for that ? thanks Thomas -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHq11UrpEWPKIUt7MRAvB8AKC1/hUoFopd911rPRcYk4NhUOFwqACgreOD QKSvo/RWbWfOd3M4X2ZyY60= =x11K -END PGP SIGNATURE- -- gentoo-user@lists.gentoo.org mailing list

Are you sure you don't have the same drain when powering off? in my experience, WOL is always a bios setting - did you look there?

Are you sure you don't have the same drain when powering off? in my experience, WOL is always a bios setting - did you look there? Yes I'm sure, I disconnect the power after everything shut down properly. And, it is time dependent. 1 or 2 Percent per hour. What happens if you suspend to disk, then take the battery out for a few minutes or more - can you resume? (put it back in of course) Yes it does come back. I have to see if there it is eating battery after putting it back in.
