    The psu or power brick stopped working on a friends laptop so i've ordered a replacement from partsmaster.co.uk. I ordered an 18.5v 3.7amp supply and they sent me a 19v 4.7amp supply. After some googling i've found out that amperage is fine as long as its the same or higher as the laptop will only draw as required but the voltage should be the same. Will .5 volt difference damage the laptop?? please advise.

    That's safe enough not to do any damage
