Slimline DVD power

gboy · 06-20-2005, 07:23 AM

Hi,
I have a Compaq slimline dvd rom that is in my glovebox. However, the power cord that come out of it plugs into the wall. I need to hardwire this into the car. So I cut the wall socket off the end, but I can't seem to find power anywhere in the car. HELP!!! Where do I hook this thing up?

Oh, this is the right thread...ok. Slim optical drives require regulated 5V which you can get from the PSU.

I have my screen hooked up to the molex, but I don't think I know where to get the 5v power. Please be more specific. Thanks.

molex =

+5v
gnd
gnd
+12v

I think the +5 is red, and the the +12 is yellow... so just tap into the other one from your screen (assuming the screen is 12v)

RoyN has it right. +5v is red and +12v is Yellow.

The red one is 5V and the black one right next to it it's 5V GND.

how do I know which line coming out of the slim line DVD is pos. or neg.? Will it say on the cord? And what if I run it into the 12v. Is that going to damage the DVD Rom? Thanks.

Have a compaq slimline DVD...USB and a power cord. I cut the wall plug in outlet that comes out of the DVD and wish to tap into power into the car. Where do I get the power? Some say the 5v molex is fine. However, after I cut the end I don't really know which side is positive or negative. Can anyone help me. When explaining pretend you are talking to a child!

Also, please look at the wall cube, and tell us everything it says. If you ca nscan it, and upload it, it will be better. Next, get yourself a volt/multi meter. You will need this now, and in the future.

Then get back to us, and we can help you out, Mostly because you asked nicely, and posted in the NOOB forum.

The back of the DVD unit only has one ide male coming out from it. I am assuming power and data go into this one pin slot. It looks to be 34 pins in the back and that is it. I do not have the wall cube anymore. (I am an idiot and threw it away). So I am left with a power cord and a usb coming from the back of the DVD. HELP PLEASE. I need to power this thing. Thanks. The model number of the DVD unit is N533. It is a Compaq.

Hmmmmm, well. That is gonna make it very difficult to connect. The housing has a certain power requirement. Not only that, there are 2 contacts for power in the housing, the pin and the shield. One of them has to have positive power, and the other has to have negative. The question is, which one is which. USUALLY, positive is the pin, and negative is the shield, but that is not an absolute, I have seen it the other way.

Also, the housing may have internal voltage regulation, or it may not. Feeding it too little voltage, and nothing will happen. Feeding to much, up to a point, will blow it.

I would suggest the following. Contact the Compaq , and ask them. GO to the store and find the same housing, and look at the box. Sometimes they say the power requirements on the box. Ask them to open the box, and look at the power cube to see what it says. OR, open the unit up, and find the board. Look at the board for voltage regulators, and try and determine what voltage regulator is in there, if possible. Then "ohm" out the pins of the voltage regulator to the power jock to see which is negative and postitive.
