i bought a dell latptop from egypt . dell inspiron 5520 core i3 third generation
the laptop came with ubuntu , but with ubuntu 11.10
ofc all drivers work , even i have dell recovery too on the ubuntu . as u can see on the middle
now i want to upgrade to ubuntu 12.4 or 12.10 . or even 13.4
sooner or later the support will stop ...
this is my hard disk
my questions :
1: how to upgrade ubuntu and keep the dell recovery and the drivers ofc?
2: should i be worried that ubuntu drivers update's miss with original drivers ?
3: can i install new fresh install and make the dell recovery on the new install ?
4: where is the power setting like windows 7 ?
5: where is touchpad setting like windows 7 ?
