I had similar problem with Asus laptop (motherboard: ASUS N501JW).Turned out to be a motherboard software problem and got fixed after a bios/uefi update to latest version available.

The flashing program I used was the one that came on windows. It have auto detecting and downloading of new updates. For your specific model, this is your drivers page. BIOS-Utilities are the Windows executable, while BIOS are the actual files to flash.

However, I have no experience in trying a flashing process outside of using windows' exes that OEMs distribute.

I was having the same issue with my Lenovo laptop running Linux mint 17.

Please update your kernel with the latest one. It will solve your problem. Follow How to update kernel to the latest mainline version without any Distro-upgrade? to update the kernel.

There may be one of the following problems

  1. Check your swap partition size using command

    # free -m

    The swap partition size should be greater than physical memory for the hibernation to work correctly.

  2. Check hibernate logs it may tell you the problem.

    tail /var/log/pm-suspend.log

  3. Add resume=/dev/your-swap-partition (of for UEFI systems resume=UUID=<partition UUID>) to GRUB_CMDLINE_LINUX in /etc/default/grub

    Regenerate your grub.conf with grub2-mkconfig -o /boot/grub2/grub.cfg (or for UEFI systems: grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg)

    Reboot -> Hibernate -> Resume. See if it works or not.

You should update BIOS with the latest firmware by using WinFlash tool. It was a solution for me, when I encountered the same problem with the sleep mode was not working properly on my Asus N501jw.
