Lenovo E320 is in airplane mode, says toggle hardware switch, but has no hardware switch and WiFi is still hard locked

Yesterday, my laptop (Lenovo E320) suddenly enabled "Airplane mode" after reboot, saying I should toggle my hardware switch to enable wifi (and bluetooth) again. The thing is I don't have such switch on my laptop.

I was running Debian testing when the problem first occured, and tried to reinstall the whole system on a brand new drive, but the problem persists. Wifi is enabled in BIOS.

I have followed several tutorials, mostly from askubuntu, but none of them worked for me.

• rfkill unblock all only fixes soft blocks
• power off, removing battery and bios reset do nothing
• reinstall (purge) firmware-iwlwifi package and restart doesn't work
• restart network-manager doesn't work
• adding "blacklist wmi" to /etc/modprobe.d/blacklist.conf doesn't work

Output of rfkill list all:

0: tpacpi_bluetooth_sw: Bluetooth
    Soft blocked: no
    Hard blocked: yes
2: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

I am getting desperate, as I am starting to think that my wifi card is broken, and I can't use my laptop with cable connection only. Any help will be appreciated.
