charger for a laptop?

mine says its an 18v, but its a bit wobbly on the connection...i have another one, HP brand, that fits the socket but is a 31,5v... i plugged it in for a second and it began charging - but the screen went black - it didnt go off though (i could still see the web page in the darkness) and when i wiggled it it came back on and was fine...

i am not going to try it again

but would it actually do any harm? or just not work very well?

cheers

i would have thought the answer would be obvious YES
if you want to b****r your laptop up carry on

I'm surprised you haven't already done harm!

You should be thankful they build protection into modern equipment!

[MarkRae]

Indeed. No doubt the screen going dim was simply the machine trying to protect itself...

Bit like putting a Ferrari engine in a Fiesta...it`ll go faster but won`t stop as good

To clarify..

Power supplies generally have three ratings that are important, volts, polarity and watts.

Volts and polarity are very important, using a power supply that does not supply the correct volts is a recipe for disaster. If it's over expect burning, if it's under it probably wont work.

Watts are only important one way, as long as the power supply can provide more than the item connected to it requires it will be fine, less and you risk the power supply over heating.

I'd be very suprised if the laptop didnt have some sort of power level detector/fuse that would kick in if the incoming power level was over a certain tolerance, and turn the machine off or at the very least block the power input
