[edit] Troubleshooting
[edit] Suspend to ram
Some R51 models might have a problem with power-drain while the laptop is in S3 (Suspend-To-Ram) mode. In order to have S3 working properly, do the following:
- Activate the following settings in the kernel:
| Linux Kernel Configuration: ACPI Configuraion |
Power management options (ACPI, APM) ---> ACPI (Advanced Configuration and Power Interface) Support ---> <*> IBM ThinkPad Laptop Extras [*] Sleep States |
- Before suspending, disable the ethernet adapter and the UltraBay. The hibernate-script can be configured to do this. A simple script to achieve this:
| File: suspend-script.sh |
echo -n eject > /proc/acpi/ibm/bay ethtool -s eth0 wol d sleep 1 echo mem > /sys/power/state |
- If problems persist, the graphics adaptor might not be suspending properly. Applying this patch to the kernel may help:
Note: This patch is written for 2.6.13.4. It might need to be applied manually.
