I recently bought a laptop in a firesale for $50, the power supply the guy gave me to power this Panasonic is Dell in origin (19volt), and the PS unit is of higher voltage than the notebook yet I was not aware of this and the notebook (Pana Toughbook old P3, 15.6volt) runs fine for days and continue to do so, was there some tweak before hand or am I missing something? I thought voltages must match.
My bigger question is can I somehow do the same tweaking and use a mismatching PS to power an LCD I bought from a junk dealer? The $10 junk computer/composite LCD is working I verified that with a PS needed for another LCD so can't just use that.

I purposely took the battery out, for reason that previous owner killed it with too serious memory effect not this, some change of reality with this?

Charging a laptop battery with an overvoltage power supply would scare me. Especially if they are lithium batteries. At least you have the charger circuit between the adapter and the battery.
For the flat panel there is no battery, you are providing a voltage directly to the circuits. If you use an adapter that is too high a voltage you stand a good chance of permanently damaging something.

If you supply too much power you run the risk of overheating and burning out a component which will ultimately spells disaster. I would look into getting the correct ps and save the heartache. As cheap as you got the laptop for, a few extra $$$ for the correct ps is worth it.
