Hi, sorry for not being clear as I could. Please refer to
https://www.howtogeek.com/196655/how-to-configure-the-grub2-boot-
loaders-settings/ , detailed steps are:
1. To blacklist wmi module:
$ gksu gedit /etc/default/grub
Then edit the line beginning with "GRUB_CMDLINE_LINUX_DEFAULT=" as:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash module_blacklist=wmi
log_buf_len=32M"
I also added "log_buf_len=32M" here to extend kernel log buffer size
so that everything since boot will be kept. Save changes, quit gedit,
and then run update-grub to re-generate grub.conf based on these
changes:
$ sudo update-grub
After rebooted, open a terminal and save dmesg:
$ dmesg -w | sudo tee dmesg.$(uname -r).blacklist-wmi
This will run forever until interrupted (Ctrl-C). Now check if your
WiFi is back, interrupt previous dmesg command and paste the saved dmesg
log.
2. To enable WMI debug messages:
$ gksu gedit /etc/default/grub
Then edit the line beginning with "GRUB_CMDLINE_LINUX_DEFAULT=" as:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash wmi.debug_event=1
wmi.debug_dump_wdg=1 log_buf_len=32M"
Save changes, quit gedit, and then run update-grub to re-generate
grub.conf based on these changes:
$ sudo update-grub
After rebooted, open a terminal and save dmesg:
$ dmesg -w | sudo tee dmesg.$(uname -r).wmi-debug
This will run forever until interrupted (Ctrl-C). Since this only
enables WMI debug messages, your WiFi should still be hard blocked, just
go ahead to interrupt previous dmesg command and paste the saved dmesg
log.

Title:
Wireless wouldn't turn on.
Status in linux package in Ubuntu:
Confirmed
Bug description:
I used Ubuntu on this machine starting with 16.04 LTS. The network PCI
never worked but USB D-Link card did work... up to recently and then
it stopped. I installed 18.04 LTS -- it read Airplane Mode On and
nothing could be done. rfkill gave me phy0 soft block no, hard block
yes. But f8+Fn only caused a pop-up message that Airplane Mod On or
Off but not in the status bar -- there it was always on with an
instruction to use hardware switch and setting wireless never worked.
I installed KDE over Ubuntu 19 now and Airplane Mode can be turned On
and Off but WiFi never turns on.
