Hi,

I have an nc4200 laptop that needs a new power supply.  I chatted with a HP consultant and he said I could use one of the new 90W slim smart adaptors for this, but that has 19.5V output (whereas the original 65W adaptor was 18.5V).  The smart adaptors "Say" they are backwards compatible with all HP business notebooks.  How important is it to match up the voltages?  Can the laptop compensate for +-1 volt differences?  Thanks!

Hi,

 

For voltage, + or - 5%-7% is ok, for wattage 90W is much better than 65W. Should be ok to use new charger.

 

Regards.
