Debian 9 Stretch - unable to reboot or shut down laptop

Postby diniwed » 2017-09-16 19:22

After upgrading from Jessie to Stretch I am unable to reboot the system. The system appears to shut down cleanly displaying the usual sequence of messages concluding with a "System Halted" or such but it does not power off and automatically restart as expected. I need to manually power off the machine and power it on again to start the boot process. The same thing occurs when I shut down the system instead of rebooting: the machine is stuck displaying the "halted" message and I have to power it off manually. As a temporary workaround I eventually found that editing the grub menu and adding "acpi=off" to the linux kernel boot paramaters takes care of this particular issue. The laptop is an old lenovo Thinkpad w700.

does acpi=off affect the laptop's usability?
if not, you can make it permanent by adding it in /etc/default/grub (and don't forget update-grub afterwards)
if yes, there is many more acpi options for the kernel; you have to find people with similar problems and try their solutions

Apologies. I realize I posted to the wrong forum. I guess I should have opened this under Help->System Configuration (?). In any case I am having other issues that could also be related to either apci or the new 4.9 kernel… and since such minor problems never get fixed in debian stable I guess that for the time being my best bet is to go back to debian 8 (oldstable) where this antiquated laptop worked more to my liking… keeping the stretch environment to look into this further if/when I have time.
