I plug in externals and headphones all the time to too many laptops.
I recently purchased a Toshiba Satellite L650-S5060 laptop. I am finding it somewhat difficult to hear the speakers. Would it be possible for me to use the speakers from my 5 year old desktop with my new laptop? The speakers have their own power supply and the laptop has a headphone jack where I can plug in the speakers. I'm afraid of damaging my new laptop with older hardware. Should I be worried?
