It's ideal that you purchase the same identical AC adapter for your unit as some components may not function correctly due to insufficient power (like in your case, the Touchpad and USB ports are inoperable). If you can still return the 65W AC adapter, I recommend you get a 90W version of it.
As for forcing the laptop to use the battery energy while charging, I believe you can't do this as the unit's configured to route the power to the AC adapter everytime its plugged-in.
