Tutorial
1. Open Your GRUB File for Editing
To fix this issue, you need to edit the GRUB file. Open a terminal and run the following command to edit the file using the nano text editor:
sudo nano /etc/default/grub
2. Modify the GRUB Configuration
In the GRUB file, locate the following line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Replace it with this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi.ec_no_wakeup=1"
Save and exit.
This change disables the wakeup event from the embedded controller, which is the cause of the battery drain.
3. Update Your GRUB Configuration
After modifying the file, update the GRUB bootloader by running this command:
sudo update-grub
This will apply the changes you've made to the system.
4. Reboot Your Laptop
Finally, restart your laptop to apply the changes:
sudo reboot
Conclusion
By following these simple steps, you should no longer experience battery drain while your ThinkPad T14 Gen 5 AMD is in sleep mode on Linux Mint or Ubuntu.
