Ccc Posted August 14, 2012 Share Posted August 14, 2012 My Laptop is dell inspiron 1464 with 10.8GM. With hibernatemode = 1 ( write memory to /var/vm/sleepimage then shutdown ), when trying to resume(press power button), chameleon log gives an error Reading image file /var/....../ blah blah blah, 512 bytes.. blah blah... Header read size 200 Incorrect Image Signature and then goes to normal boot. With hibernatemode = 0 (keeps memory active while shutdown LED and harddisk), and wakeup is perfect. In org.chameleon.Boot.plist there is darkwake=0 USBBusFix = Yes smbios is set as MBP61 2 USB highspeed recognized as extended(EHCI?)。 chameleon version: r2033 In Windows 7 i can confirm that the power management S3 mode is supported while S1/S2 not, and the hibernate works with Win7. But in BIOS settings there is no option for this. Why it does not work on 10.8? In 10.6 the deep hibernation works fine on my laptop. I do not know if the info is enough, please let me know if more info is needed. CPU i5-430m, speedstep works with ssdt, audio alc269 working with patched applehda, ati 4330m works with modified ati4600controller.kext In the attach there is my DSDT file.

HUSABER Posted August 14, 2012 Share Posted August 14, 2012 Try this: fsck -fy mount -uw / rm /var/vm/sleepimage reboot 1 Link to comment Share on other sites More sharing options...
Ccc Posted August 14, 2012 Author Share Posted August 14, 2012 Try this: fsck -fy mount -uw / rm /var/vm/sleepimage reboot I thought this is used for when booting into -s mode. Anyway, I will try this, first boot into single mode, delete the sleepimage and reboot, and then try deep hibernate. Link to comment Share on other sites More sharing options...

MontMac Posted April 3, 2013 Share Posted April 3, 2013 Hey, Ccc... sorry to revive a dead thread but did you fix the issue? I fixed it on my computer by manually removing the sleep image file. Link to comment Share on other sites More sharing options...
