Known Issues
- Bootable USB detection by the BIOS can be slow or flaky at times, need to restart the laptop again.
- Out of the box battery life is lower compared to Windows, need to tweak the defaults using TLP & Powertop.
- PCIe spams error messages in the journal, to fix this add
pci=noaer
as kernel parameters. - PCI Express Active State Power Management does not work. Use BIOS recommended defaults.
- AHCI Power Management does not reliably work for some SSD brands, especially Samsung. Use BIOS recommended defaults.
- Wi-Fi speeds can get throttled when using on battery power, in that case disable power management for the Wi-Fi chipset.
- Using TLP and
powertop --auto-tune
(run as the root user) will cause conflicting power settings and disabling of Turbo boost when plugged in.
BIOS Firmware Settings
Set supervisor password first, only then you are able to change Secure Boot option
- Secure Boot: Off
- Touchpad: Advanced
Kernel Boot Parameters
-
pci=noaer
to disable advanced error reporting for PCI devices.
Custom TLP Settings
tlp.conf
before making below changes. Do not use TLP and powertop --auto-tune
(run as the root user) together, it will conflict the power settings.- You will need to install TLP & Powertop.
- These settings are aimed at moderate-high power savings when on battery power and high performance when connected to a power source.
- Add below lines at the end of your
/etc/tlp.conf
, You will need to modify them further to suit your usage pattern.

- Type
tlp start
(as the root user) in the terminal to start TLP using custom settings. - Type
tlp-stat -c | sort
(as the root user) in the terminal to view your custom settings which should present in the end of the output. - Type
powertop
(as the root user) in the terminal, go to Device stats and Tunables tabs to view your current power consumption and parameters which need to be tweaked further.
Custom Powertop Settings
powertop --auto-tune
(run as the root user) together, it will conflict the power settings.- You will need to install Powertop.
- These settings are aimed at balanced power savings when on battery power and when connected to a power source.
- You will need to modify these settings further to suit your usage pattern.
