Laptop power supply - technical question?
I have a HP laptop which uses a power supply giving 18.5V
The power supply died and I have bought a generic replacement.
The amps and watts are fine - but the multi-volatage selector only operates in whole Volt steps.
I can choose 18V or 19V - but not 18.5V
So - my question is which is better .5 volts over - or .5 volts under.
Guesses not needed - I can guess myself!

.5 under gives the chance of "brownout" which means some components do not receive appropriate voltage/ or wattage. Going .5 over allows everything to work, but, may cause certain components to fail from overload. if you must use this supply, then i suggest going .5 over. recommend however to appropriate the proper supply asap.
