I have a HP-HDX18 laptop and the 120w ac adapter gave out on me and is
can't be fixed.
its specs are:
INPUT: 110-240~2.4A 50-60Hz
OUTPUT: 18.5V 6.5A 120W

i have another HP ac adapter that works but the output watts is only
its specs are:
INPUT: 120-240V 50-60Hz
OUTPUT:18.5V 3.5A 65W

So my question is, will using this spare AC adapter with a lower amount
of watt output be harmful to my laptop or just not work?

Thanks in advance.
