  1. I recently damaged my genuine laptop charger and couldnt find a charger with the same specs, the only one I found had a lower standard, it works fine but I am afraid of damages on the long run, any ideas?

    Hp pavillion dv4
    old charger output 19V 4.74A 90W
    New charger output 18.5V 3.5A 65W

    Thanks....

    your risk is to the charger, not the laptop.
    old charger output 19V 4.74A 90W
    New charger output 18.5V 3.5A 65W​
    the voltage difference is only 0.5v , the big difference is the
    current output.

    googling for Hp pavillion dv4 I found the hp dv4 spec to be
    Power

    * 65 W AC Adapter
    * 6-cell Lithium-Ion (Li-Ion)​
    which is IDENTICAL :)

    I guess you have a match with the new charger and the original was just a bonus
