How to make this American laptop work in the UK?

After months of searching I have finally found a HP ENVY 14 with Radiance display however the laptop is American and I'm unsure on whether to go through with the purchase.



The adaptor section of the specs say that the laptop takes 90W AC but i don't have a clue what that means and whether it will work here. Would it just be a case of buying an adaptor in England? would that fit in the laptops power port? or do I just need a plug converter?



I don't really want to have a plug converter because they look clumsy and unattractive.

Hi

You just need a two pin to three pin adapter and to change the voltage switch on your laptop to 240 volts (that is very important..or else bye bye laptop).



A shaver adapter will do (cheap),but you can spend a bit more and get a two plug adapter (plug two devices into one socket) -

Yes just a plug converter, or a new adapter would be fine
