@ Randy,

I replace dc jack on HP ZD7000 laptop . And now when i hit the power button all the top lights flicker it wont power up . It did power up before I worked on it, This is real what do think went wrong ,,only I did notice one pole didnt have a complete connection so i scrap the green away to see cooper and add more solder to bridge it but that did nothing to improve it the lights all flicker when i press power button

Maybe this problem is not related to the DC jack?
You said all lights flicker and it means the laptop is getting power through the jack.
I really cannot tell what is wrong without looking at the laptop.

Check the video cable connection on the motherboard. It’s possible the video cable not seated correctly. Try reseating the connection.

Jasmin, your battery is probably dead and unable to take a charge, so try a new one.

cj2600, thanks for the info in your article. I’ve salvaged the connections on a few damaged vias myself but they usually don’t come out looking as good or reliable as yours. The last laptop DC jack I worked on came out well, but you must admit that it’s easy to lift out the vias when the joint won’t heat up with a lower wattage iron, especially when you’re working with ground shields/planes which dissipate the heat too quickly.

My compaq presario CQ40 is currently out of warranty. And i found that when i plug in the batteries without AC, it cannot be turn on. Only when i plug in the AC then it can be turn on. But even when i turn on, i doesn’t appear BIOS and everything was blank. One of the thing i could notice is that, the both LED white light keep on blinking after the laptop was switched on. 1st LED light is located on top of “Num lk” key, and 2nd LED light located on the side of “Caps Lock” key.
can u help me figure out this problem.tq

Jon,

I have a Compaq Presario F700. When I plug the DC adapter into the laptop port the blue ring led on the port comes on solid and stays on. However, the laptop does absolutely nothing when I press the power button.

1. Possible memory failure. Try removing memory modules one by one. Test the laptop with each memory module separately, try different slots. One of the modules could be bad.
2. If replacing memory doesn’t help, this could be motherboard failure. Probably related to the graphics chip failure.
If you have nothing to lose, you can try this trick: http://www.laptoprepair101.com.....hics-chip/

However, the laptop does absolutely nothing when I press the power button. I’ve attempted the hard reset methods and everything else I can think of. I know the jack on the mobo feels a bit loose when I wiggle the plug, could it be the jack even though I get the charger connected light still?
