I have a y560 with a quad i7 Q740.
Looking for an extra power adapter. I know you can run into problems if you don't match up the Voltage properly, but will you have problems if the Wattage is low?
The stock adapter runs at 120 W 19.5V 6.15A
I've seen some decently priced replacements at 19.5V & 90W.
Don't want to damage my machine.

That was my plan, but I was looking for a more scientific explanation. I mean, from what I can tell, less Watts would mean the battery would charge faster, as long as the Volts are up to par.

Hehe, that would help =]
Sorry if I sounded offish. I appreciate your help here and all over the forums.
Just trying to understand the science a little bit =]

Yes, from what I've read, less wattage would be perfectly fine, but once you start revving your CPU/GPU, it is potential you would start draining your battery WHILE plugged in.
So, OEM it is, since no one else sells the 120W variant that I can find.
