Laptop adapter wattage?
I broke my adapter and a store near me sells replacements.
According to Toshiba's site, my adapter draws 75 W. The store only sells 70 W or 90 W adapters. Does the wattage have to be exactly the same, or will it also work if it's more? (or less, but I don't think it'd work if it were less, would it?)
Sorry, I know very little about computers.

its far better to get the exact right one.
The Wattage is a measure of how much power can be supplied.
without getting into ramblings on this, it is important, but if you
look on the underneath of theOLD power supply it will actually
usually give an AMPS value and an Output Volts value.
these are the important things. And it will also have a graphic
to explain Which is +ve the Outer connection or the Inner
connection of the bit you push into the laptop
this is also important
to sum up then
1) check connection Polarity Graphic (inner plus(+ve) Outer minus(-ve) is typical )
2) check output volts, usually 17..20Volts this needs to be the same +/- 0.5V
....of the OLD one.
3) check the AMPS 65Watts should be about 1.6 Amps. less than this is too low
More Watts is better as the pc will use what it wants, but it must be at the correct volts
with 0.5volts preferably
Hi
it would be best to buy the 90watt version.
