I see this too, but only when I plug in power when the laptop is running. If I boot up with AC connected, the disk does not spin down. Probably the system just misses the transition from battery to AC here. I assume it has something to do with laptop-mode missing the event. After I plug in power, laptop mode is on state "2" (whatever that means). After running the laptop_mode program, it jumps to "0", and the disk does no longer spin down:
$ cat /proc/sys/vm/laptop_mode 2 $ sudo laptop_mode Laptop mode enabled, not active $ cat /proc/sys/vm/laptop_mode 0 -- [Dell M1330] Hard drive spins down often, even on AC power https://bugs.launchpad.net/bugs/362047 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
