I have a Lenovo Ideapad 3, and have been running single boot KDE Neon (20.04 focal) for years. Yesterday my desktop froze. Upon reboot, I found myself with no touchpad, no function keys (with the exception of the Volume keys that continued to work), and no WLAN.

Except the Function keys, there are no other keys on my laptop that can control hardware.

According to the BIOS, WLAN as well as Function keys are enabled.

I disabled the ideapad_laptop module with modprobe -r and by blacklisting in /etc/modprobe.d/blacklist.conf which briefly got the WLAN working. At this point, I updated my sources and upgraded my packages. Upon reboot, I found that my WLAN was now once again not working, but touchpad is working.

Further experimentation with the ideapad_laptop module yielded no results. Disabling it removes the ideapad_wlan and ideapad_bluetooth entries from rfkill list, leaving hci0 Bluetooth and phy0 WLAN. This has no effect on Bluetooth functionality. As per the title, phy0 is hard blocked. As expected, rfkill unblock all does not change this.

The lshw -c network command tells me that I have an Intel Dual Band Wireless-AC 3165 Plus Bluetooth network controller, and the lspci command tells me that my Kernel module and driver in use is iwlwifi.

I've tried running Arch and Neon live from USB, but phy0 continues to be hard blocked, and no function keys. Any thoughts?

SOLUTION: remove battery.
