Package: util-linux Version: 2.20.1-5.2 Severity: important File: /sbin/hwclock
Dear Maintainer, For the longest time I've had this problem where the laptop battery would drain (at a pace of ~25%/day) when the system was off. After I sent the laptop to the lab, they reported that the problem doesn't occur when they put in a Windows HD, only on my Debian system. So I searched the web, and found a Gentoo user who ran into the same issue and managed to work around it: http://www.linuxquestions.org/questions/linux-laptop-and-netbook-25/battery-drains-while-off-acpi-related-4175429035/ http://forums.gentoo.org/viewtopic-t-937674.html?sid=9d820102619ebab6feb7e725a82a9fca I changed my own /etc/init.d/hwclock.sh (the modified version is also included later): /etc/init.d$ diff hwclock.sh{.dist,} 101c101 < if /sbin/hwclock --rtc=/dev/$HCTOSYS_DEVICE --systohc $HWCLOCKPARS $BADYEAR; then --- > if false && /sbin/hwclock --rtc=/dev/$HCTOSYS_DEVICE --systohc > $HWCLOCKPARS $BADYEAR; then And the drain slowed down to ~5%/day, which the tech-support tells me is normal. I marked this "important" because it affects hardware and can interfere with usage of the whole machine, I hope that's ok. Also, I realize it's pretty likely that the problem is really in the kernel, but it's hwclock that was caught red-handed. Thanks, Shai. PS: For my usage pattern, having the clock updated properly is more important than keeping the battery full, now that the test is done, I'm going to restore the hwclock.sh script. -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages util-linux depends on: ii debconf [debconf-2.0] 1.5.46 ii dpkg 1.16.9 ii initscripts 2.88dsf-34 ii install-info 4.13a.dfsg.1-10 ii libblkid1 2.20.1-5.2 ii libc6 2.13-37 ii libncurses5 5.9-10 ii libselinux1 2.1.9-5 ii libslang2 2.2.4-15 ii libtinfo5 5.9-10 ii libuuid1 2.20.1-5.2 ii lsb-base 4.1+Debian8 ii tzdata 2012g-1 ii zlib1g 1:1.2.7.dfsg-13 util-linux recommends no packages.
