Public bug reported: Hello,
I have a Brand New (3 days old) Lenovo Ideapad model 2PU. The computer suspends fine, and goes to a blank screen from X, however, the hardware lights never turn off and caps lock flashes. After it flashes and harddrive spins down, the computer is unresponsive, and no key combination results in a reboot. However, the fan never turns off. I am forced to hard reboot. I have the same problem when I attempt to suspend without X, i.e. press Ctrl+Alt+F2, then type pm-suspend. The computer does not generate a pm-suspend log. This computer has no driver installed for its graphics card (Nvidia Geforce 9300M). In fact, this is a completely new install with NO new software whatsoever. There is no partition on the disk, and the swap size 7.1 GB with 3Gb of ram. Previously, I had installed ubuntu with the proprietary drivers from Nvidia's website, and I had a similar problem there, except at that time the computer would power down for a split second, and then return to a screen with a blinking cursor. In this case the computer did generate a pm-suspend log, which indicated success. I have a post about this here: http://ubuntuforums.org/showthread.php?t=1140717 ------------------------------------------------------------------------------------------------------------------------------------- Attempting to suspend using the method listed here https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume gave no results. Enabling no_console_suspend did not change anything and entering the commands: setfont /usr/share/consolefonts/Uni1-VGA8.psf.gz sudo pm-suspend did not make any extra text appear on the prompt. ------------------------------------------------------------------------------------------------------------------------------------- Attempting to trace the error using the method here: https://wiki.ubuntu.com/DebuggingKernelSuspend gave no results. The dmesg file only had the "Magic number," listed once and there were no "hash matches." This method did not work either http://lxr.linux.no/linux/Documentation/power/s2ram.txt ------------------------------------------------------------------------------------------------------------------------------------- Attempting to use the s2ram method listed here http://en.opensuse.org/S2ram gave no results. Every combination I tried did not work. ------------------------------------------------------------------------------------------------------------------------------------- Attempting to look add "quirks" manually as they do here http://people.freedesktop.org/~hughsient/quirk/quirk-suspend-debug.html gave no results. In fact I ran the script listed at the top of the page and it said that my computer will suspend correctly. ------------------------------------------------------------------------------------------------------------------------------------- Attempting to use the debugging here https://wiki.ubuntu.com/KernelTeam/SuspendResumeTesting gave no results. The computer had the exact same systems under this test, and no report was generated with apport. ------------------------------------------------------------------------------------------------------------------------------------- The bios has no power settings either then allowing the screen to dim, or to allow the computer to use Wakeonlan. I disabled wakeonlan and tried to suspend and there was still no difference. ------------------------------------------------------------------------------------------------------------------------------------- I have attached a few relevant logs. Please let me know if you need any more information.
