Your asking about the end that goes into the wall correct?

99% of the line cords I have seen (in the US) Have a green, white, and black wire where:

Black = Hot
White = Neutral
Green =Ground

I would suggest you use a multimeter to find which wire does what without checking it directly I would need More specifics about the laptop/power supply

The XPS M1330 has no video card, the video circuit is integrated into the motherboard. To determine if the video circuit or LCD display is the culprit, try connecting an external monitor to the 15 pin VGA plug on the side of the laptop. If the display on the external monitor appears normal then your LCD on the laptop is the problem, if not then you need a new motherboard.

Which wire out of blue and brown is the ground on a Toshiba charging cable


The standard according to 17th Edition Electricians Guide is;
Brown = live
Blue = neutral

There is no ground with that colour using mains cable.
If it is a secondary supply, it could be either way around as it is non standard.

No power, no lights on laptop


I think you should check the real power supply ... 120 V in and what comes out ... volts (ac - dc) and amps or what fraction of an amp.

Please compare the old with the new power supply. The new power supply should be the same volts - same kind (AC or DC) and at least the same amp rating. You can use higher amp rating but not lower - lower will burn up - literally)

Volt meter ... always set it above the suspected voltage. Batteries are always DC. Houses, buildings, etc always AC. Power supplies - could be mixed - ac in and dc out.

So if you were measuring in your home, you set the meter to 130 or higher on the AC scale. If you were doing your auto, 24 volts DC (or so).

House current, probe color doesnt make any difference. Should read about 120 Volts between the narrower (or right side/ground down orientation) or the two slots and the wider of the two shots (wide should be the neutral side - ground on the bottom). You can prove the hot side by measuring to the ground. White wire to ground = no reading. Black wire to ground = 120 volts. (The black and white are INSIDE the electric outlet. You can use either probe to do the measurement.

I hope this helps you.

If you have more question, please let me know.

to identify them. power supply wire is easily identified by checking voltage.
ground wire u may ceck by continuty from ground.
rest wire u may test by try basis one by one. there will not any fault for doing so.

Dv6500 adaptor pin connection


Color code is probably not the solution. Look in the manual for the pin out. Borrow a volt meter and power up power supply. With meter on dc volts measure voltage and notice polarity. My guess is blue is positive and bule stripe is the return for that supply, Hope this helps.

To turn on an HP, make sure you have the AC adapter plugged in properly, and press the power key. But since you imply it has been a while since this was on, I suggest removing the battery BEFORE you start the first time.

The power key is identified by an ICON best described this way: a circle with a vertical line in the center. The vertical line is sometimes centered in the circle without touching any edges, and sometimes it is crossing the top of the circle slightly.

Once you have started the laptop and get to an OS desktop, you should check everything out to make sure everything works.

Then SHUT down, remove the power supply, insert the battery, reattach the power supply and start again.

Monitor the battery charge progress carefully. If the battery fails to charge, it will need to be replaced. This is because no matter how new a battery is, if it is left for extended periods in an uncharged state (or worse, fully depleted state) the battery will usually be defective. It cannot ever be recharged because at least one cvell will be dead.

As for the power cord, using a three-prong plug will be useless if you do not have a 3-prong jack and 3-wire cable. but if you do, you can cut off the useless 2-prong euro plug, strip the 3 wires and install a 3-lug grounded plug. Pay attention to the polarity then, because it is critical on 3 wire connections. In USA, black, white and green are the color codes. Green is the ground. In Europe, the colors are different and varies widely. Blue or brown will be the ground. You will need a VTVM to trace the continuity to the other end, to identify which is load, neutral and ground (earth). Be careful. Ifr you connect AC load to ground, you may damage your PSU -or the HOUSE !!!! :)
