That's the weakness with laptops, very hard to upgrade. Can't even change the knackered battery on this one
Mine was quite good (i7)... the battery is knackered and I have to keep it plugged in all the time.. I could change the battery but it only runs Win10 and the upgrades are killing it...
This new one comes with a little carry case so you can take it with you and plug it into the hotel telly or whatever...
