Default laptop AC adapter tolerances

Thanks for that, I wasnt su I knew that the 6A wouldn't be a problem
as the unit doesn't consume any more amps than it needs but didnt know
that if it only needed 19v, the adapter wouldnt just keep on pumping 20v
into it


Regulation on a lot of supplies is within a volt anyway. Unless the
charging/distribution electronics of the laptop are poorly designed
I wouldn't anticipate one extra volt being any problem. I've been using
an HP 20 volt supply on a Toshiba that ran on 19 and like I said no
problems after a couple years. I'm also using a 19 volt Dell supply on an
Asus that takes 19 volts. However when measured the 19 volt supply
outputted almost 20 volts. There are no + - tolerance specs printed on
the side of the supply. If it were plus or minus 5 % that would be pretty
close to one volt either way on 19 volt output.

I've used a 90 watt 20 volt adapter on a laptop which requires 19 volts
at 55 watts for maybe 2 years now with no apparent damage. 1 volt isn't
likely to be an issue and the laptop will not consume more power than
it needs.
