Oh no I can’t tell you how to fix it! Sorry! Gave the wrong impression there!
Don’t worry I wasn’t expecting how to fix it from what you had posted but did think giving a bit more info was a good idea. My thanks were for taking the time to look at your setup.
I’m equally not expecting someone to dig around looking for answers. So many knowledgeable people on here in lots of different walks of life so always think it’s worth a punt asking here just in case before hours of internet searching and I try and do the same where I can.
I’m only really trying to work out if it’s worth the trouble of making a usb install stick on the other computer or just punt it back to Asus (rapidly becoming preferred option!).
Thanks also @sharkbait I’ll probably try warranty before Ubuntu. But if they won’t fix it then that may be a plan.
Thanks again folks.
