hey guys so i purchased my Lilliput recently and now i am looking to get a carnetix cnx-1900. The only problem is that i dont know if the cnx will work with my laptop. It is a Compaq Evo n1020v and the stand alone power says 14.4V. So if i want to use this as my primary (cnx has 18V 19V and something else) and the screen as my secondary (12V) and something usb as my add on (5V), am i able to use the CNX primary to my laptop even though it is only 14.4V?
here is where i got my info from: http://h18000.www1.hp.com/products/q.../11455_na.html
Pumping 18V (P1900 minimum) into your 14.4V laptop isn't a good idea. Safest bet is to try to get a car adapter for the laptop and connect that to the 12V source on a P1900 or other power supply/regulator. If that doesn't work, you could probably work out some sort of resistor circuit to cut down the 18V but the easier way is to power an inverter from the PS/regulator and just plug the laptop into that.
hmm, then i cant connect the screen into it bc its also a 12V source
Sure you can...as long as you don't try to pull more than the 140W it can supply.
I meant if you were running a 12V car adapter or an inverter for the laptop, you'd just run everything off the 12V (a different PS would probably be cheaper/better but this is what I'm doing with the P1900 in my car and it works great). Otherwise, I'm not smart enough electronically anymore to tell you how to drop the 18V down to ~14V (you'd then run the monitor off the 12V source).
do you by chance aim or some sort of IM
do you mind explaining the inverter thing again; by it did u mean...connect the inverter to the 18V?.....the screen to the 12V and what ever else i used to the 5V
