Scheda tecnica
Installazione
Consultare la relativa guida.
Nel notebook è possibile installare un disco aggiuntivo, poiché è fornito internamente di una porta SATA oltre allo slot per SSD m2. Sono supportati sia quelli SATA sia quelli PCIe.
Impostazioni Uefi
Per installare Ubuntu disabilitare la funzione di Secure Boot.
In caso di dual boot con Windows, disabilitare anche la funzionalità Fastboot all'interno delle impostazioni Uefi, per consentire al boot loader GRUB il corretto avvio di entrambi i sistemi (l'avvio del computer sarà più lento di alcuni secondi).
Rilevamento dell'hardware
Dispositivi connessi
Per verificare il corretto rilevamento dell'hardware del portatile, digitare in un terminale il seguente comando:
lspci
Il comando precedente restituirà una schermata simile alla seguente:

Processore
Per visualizzare i dettagli sul processore, aprire in lettura il file /proc/cpuinfo, digitando in un terminale il seguente comando:
cat /proc/cpuinfo
Il risultato sarà simile al seguente:

Interfacce di rete
Con Ubuntu 18.04 lo strumento Driver aggiuntivi rileva la scheda di rete wireless Intel 8260 come non funzionante. Tuttavia durante ripetuti test non si segnalano malfunzionamenti della stessa.
Touchpad
Risulta non funzionante il tasto fisico con cui è possibile disattivare il touchpad tramile il doppio click (posizionato in alto a sinistra del touchpad stesso), nonché il relativo led.
Tasti rapidi
Bluetooth
