Does hybernate/wakeup work?

Rate this Message:
I tried to make system hybernate with 'acpiconf -s4' on my laptop.
It quickly turned off, but when I press the power button it boots like no hybernate and begins to check disks. What can be wrong?

OS S4 is not implemented, but BIOS S4 is possible on some machines ... And on 8.0 and 9.0 i386 SMP doesnt resume properly (amd64 works). _______________________________________________ freebsd-questions@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@..." |

Power button begins to flash, when I press any button there is some disk activity, power button light turns on. And nothing happens. 'apm -z' produces similar result. Maybe it's better to ask what works? Is there any way I can use suspend/sleep mode? Any basic way to make it sleep?

It matters, which is why we ask for uname -a .. obscure your hostname etc if needed. Some Atom models (230 and 330, I read) have feature 'LM' and so can run amd64; others don't and must run i386. > Laptop is Lenovo S10-2, single CPU, Intel Atom. But with hyperthreading enabled or not? How many CPUs launched (dmesg)? Again, it matters. As I understand it, on 8.0 amd64 SMP suspend/resume (S3) should work, i386 SMP is currently broken, i386 non-SMP should (still) work, but I'm really not sure about the Atoms. head -50 /var/run/dmesg.boot (or so) should clear this up. We don't need the whole thing, but show anything to do with ACPI and CPU(s). > --- sysctl hw.acpi output --- > > hw.acpi.supported_sleep_state: S3 S4 S5 > hw.acpi.power_button_state: S5 > hw.acpi.sleep_button_state: S3 > hw.acpi.lid_switch_state: NONE > hw.acpi.standby_state: NONE > hw.acpi.suspend_state: S3 > hw.acpi.sleep_delay: 1 > hw.acpi.s4bios: 0 So, hibernate won't work. There was talk of someone doing that for a Google SoC project but I've heard no more about it for a long while. > hw.acpi.verbose: 0 > hw.acpi.disable_on_reboot: 0 > hw.acpi.handle_reboot: 0 > hw.acpi.reset_video: 0 > hw.acpi.thermal.min_runtime: 0 > hw.acpi.thermal.polling_rate: 10 > hw.acpi.thermal.user_override: 0 > hw.acpi.thermal.tz0.temperature: 43.0C > hw.acpi.thermal.tz0.active: -1 > hw.acpi.thermal.tz0.passive_cooling: 0 Slightly surprising, but again I know nothing about Atom BIOSes. > hw.acpi.thermal.tz0.thermal_flags: 0 > hw.acpi.thermal.tz0._PSV: -1 > hw.acpi.thermal.tz0._HOT: -1 > hw.acpi.thermal.tz0._CRT: 102.0C > hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 > hw.acpi.thermal.tz0._TC1: -1 > hw.acpi.thermal.tz0._TC2: -1 > hw.acpi.thermal.tz0._TSP: 300 > hw.acpi.battery.life: -1 > hw.acpi.battery.time: -1 > hw.acpi.battery.state: 7 > hw.acpi.battery.units: 1 > hw.acpi.battery.info_expire: 5 > hw.acpi.acline: 1 > hw.acpi.cpu.cx_lowest: C1 If this is either i386 uniprocessor or amd64 SMP, suspend/resume should work, though possibly needing some settings tweaked and/or some modules unloaded/reloaded in /etc/rc.{suspend,resume} to do so successfully. If so, I'd next try the freebsd-mobile@ list where several people who should be able to advise on this tend to hang out. If not, you may be out of luck at this stage. cheers, Ian _______________________________________________ freebsd-questions@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@..." |
