Fix Toshiba Satellite U400 Not Resuming from Suspend

suspendtoshiba-satellite

I have upgraded from ubuntu 10.4 to 10.10 and the issue seems to be that when I close my lid I have set the computer to suspend. When I open my lid I get a black screen with the login but keyboard is not working. I am using a Toshiba Satellite U400, and didn't manage to find something suspicious at my log files. Any ideas?

I have a Toshiba U-400, and Maco's answer here is similar to Pitto's.

In our case, it's the bluetooth module that prevents the laptop from resuming from suspend. You need to add this line to /etc/default/acpi-support.

MODULES="toshiba_bluetooth bluetooth btusb"

That should get you running again. Despite this change, perhaps 1 in every 25 or so suspends (not resumes) will fail for me. When it fails, it cycles the CPU and fanspeed up pretty high. Do not trust this laptop to suspend correctly. It suspends very quickly, so when you close the lid, keep your eye on it for the 3 or 4 seconds it takes to complete (the amber light under the trackpad should go off).

If it doesn't, you're looking at a fire hazard!

Ubuntu – Ubuntu 14.04 resume error after suspend

Solution worked for me (copied from my personal manuals without modification). I've got Lenovo T530 with Ubuntu 14.04; mainline kernel 3.14.9; nvidia-331-updates package installed (331.38-0ubuntu7).

=> suspend/resume works for me quite well. => I was solving also problem with resume after hibernation, and the solution: eject SD card from the laptop! :-|

My comments that worked for me (some months ago):

suspendResume_WORKING() {
# WIFI solution
# 1.) sudo vi /etc/pm/config.d/modules
# 2.) Replace SUSPEND_MODULES with this line:
#         SUSPEND_MODULES="$SUSPEND_MODULES uhci_hd button ehci_hd iwlwifi"

# SD card solution:
# 3.) Copy file from https://github.com/wschaub/T530-    settings/blob/master/pm/sleep.d/unmount_sdcard
#     to /etc/pm/sleep.d/unmount_sdcard
# 4.) chmod +x /etc/pm/sleep.d/unmount_sdcard

# ACPI solution:
# 5.) Replace lines in /etc/default/grub
#     GRUB_CMDLINE_LINUX_DEFAULT="noquiet nosplash acpi_osi=Linux acpi_backlight=vendor acpi_sleep=s4_nohwsig loop.max_part=63 loop.max_loop=64"
#     GRUB_CMDLINE_LINUX=""


# X.) sudo update-initramfs -u
# X+1.) sync; sudo reboot

}
