[QUOTE="uninfected1, post: 736935, member: 48923"] Excellent thread and it's pretty much answered all the questions I had about buying a suitable power supply. Thanks a lot for all the detailed information [USER=59833]@Digerati[/USER]. So to summarise, the golden rule is that voltage must always match what is stated for the machine, and if in doubt about amperage and wattage, go higher but never lower. In fact, my original power supply ran quite hot so going higher might be better. And polarity should never be reversed. EDIT: After I started this thread I found this article which sums things up pretty well. I should have done a bit more googling before posting:) [URL='https://askleo.com/can_i_use_a_power_supply_with_a_higher_wattage_rating_on_my_laptop/']Can I Use a Power Supply with a Higher Wattage Rating on my Laptop? - Ask Leo![/URL] [/QUOTE]
