Help needed for Lenovo Ideapad S145

Just bought this laptop, cause my old one is about to die. I have disabled secure boot. Trying to install Fedora 30 KDE, the touchpad is disabled, I could only use the TAB key to navigate. But I managed to install Fedora. Thinking that once installed, I would have full navigation keys. Not so.
With Fedora now installed, only the TAB key works. I cannot activate wi-fi, nor the touchpad. Basically this is just a pretty brick.
Any help that could get me going would be appreciated.

If possible, update BIOS/EFI firmware and collect some hardware information :

lspci -k -n -n
lsusb

Try to blacklist vendor specific kernel modules if any:

lsmod | grep -e ideapad
sudo rmmod ideapad-laptop
echo blacklist ideapad-laptop | sudo tee /etc/modprobe.d/ideapad-laptop.conf

Thanks for replying, I have to locate an external mouse then I’ll give it a try. My only tool so far has been Krunner and that hasn’t been easy.

I have realized the major blunder I made, buying this laptop. I knew that Realtek was a problem in linux. But all the posts that I have read concerning Lenovo, were not too scary. It seemed that eventually the issues were resolved, albeit after a bit of work.
This laptop comes without an ethernet interface, so installation of drivers and the like offline is not trivial. To cut my losses and regain some peace of mind, I have decided to purchase an wireless dongle (known to work with linux), the Panda 300Mbps Wireless N USB Adapter.
So anyone considering buying this laptop, I suggest take the easy road, plug an external mouse, get a wireless dongle. Better still, stay away from it.

I was/am thinking about buy a laptop in the future, I did read a bit about some companys with good support of linux like dell but I am more interested in Lenovo and I did find this link --> www.lenovo.com/linux

I am sorry it is coming too late and now is not helping you, but sure you will solve the issue you have what a bit of work like you said. This communty has good experenced members (I dont talk for me :sweat_smile:) that sure will you in the way.

I wish you the best of luck!
Regards.

Thanks for the kind words. It is always “Buyer beware”, I was a bit rash. I got fed up with my current laptop acting up and did not want to wait until its demise.
Have a nice day. :sunglasses:
