Does anyone have the experience of modifying a typical laptop power brick so
that it may be used to power a non-laptop ATX motherboard?
I have a home-made "set-top" box which usually has the following components
connected and nothing else:
one microATX motherboard with on-board video and on-board sound
one 600 MHz Celeron CPU,
64 MB PC133 RAM,
one 4GB laptop hard drive (adapted for use in a non-laptop environment),
one character LCD display (connected via a serial port),
one external USB keypad
Right now, I have modded a regular ATX power supply (replacing the bulky
metal case with acrylic covers for protection), put the insides of the PS in
my box, and mounted the PS back-panel at the back of my box. Everything
works great.
My "dream" is to get rid of all this ATX PS stuff and see if I can take a
"laptop" approach to powering. To be more specific, say I have a Dell laptop
power brick with the following specs:
AC input: 50-60Hz, 100-240V, 70-90VA
DC output: 18.5V, 3.8A
Would it be insanely messy to derive all the power lines needed for the ATX
power plug on the motherboard from the laptop power brick? All suggestions
will be greatly appreciated.
