Question about HP Pavilion dv6000z Notebook
I have run into this many times and have found several solutions for your particular case.
The 1st and easiest thing to check (and fix) is whether or not the laptop's cooling fan has become clogged. Sometimes blowing compressed air through the cooling fins on the back will blow the dust bunnies out that are holding the fan still. The trick is to blow the air in the opposite direction of the exhaust. If their happens to be a bunch of lint trapping the fan then a more advanced procedure to get the debris out may be needed. Sometimes a paper clip from beneath (between the grills) and you can fish the worst out.
The other problem could be your power supply has given up the ghost. I recomend doing this little test... Take the battery off leaving the power supply on. Try to POST the computer (where the HP logo comes up and you see a bunch of DOS style letters at the base of the screen), if it gets there and then shuts off, you may have a bad power supply. Grab a friends (if you can) and try it in place of yours. Obviously, if you can boot into Windows, problem solved. If NOT, then there is a serious issue deeper into the system than can be easily walked through in this forum.
The best case of this scenario would be that the CPU took a hit and replacing that could remedy the situation. Otherwise, its a same voltage regulator mounted on the motherboard and not really within repair parameters, but replacement of the actual motherboard; which may not be cost effective for you.
Hope this helps...

The only internal power for a laptop is the battery. The external power is the AC adapter. (Charger)
If you're asking for the schematics, for the circuitry and component layout of the motherboard, to my knowledge only HP trained authorized technicians, have access to this. In truth, if they have a problem, they just replace the entire motherboard. It's more cost and time effective.
Which leads me to this. The main issue of power problems for a laptop, is the DC Power Jack, right after a failing battery. This is the round port on a laptop, where the AC adapter plugs in. Although replacement of this jack, is no 'Walk in the park', it isn't that tough. However, there aren't that many of we tech's around, who do this anymore. There are just a bunch of 'Parts Changers' out there. Still, from a laptop manufacturers point of view, it may be more time and cost effective, to just replace the motherboard. Less chance of that laptop coming back for the same issue.
I state, that the DC Power Jack is the main source for laptop power failure, right after a failing laptop battery because, the jack receives a lot of accidental abuse. When the AC adapter is plugged in, and the plug of the adapter receives a heavy 'bump', the DC Power Jack can break, or it's solder connections can break, very easily.
This is an enlarged photo of an average DC Power Jack, http://us.st12.yimg.com/us.st.yimg.com/I/yhst-42877593004970_2046_1476209 You can see the 'body' of the jack, is not much larger than the plug that goes into it. The body is also made of plastic.
The thick pin in the center is the Positive connection. The outer metal shell inside, is the Negative connection.
Sometimes the plastic body can break. Sometimes the connection at the end of the center pin, can break. Sometimes the cylindrical metal outer shell, inside the body of the jack, can break.
There is also another issue. In the photo the DC Power Jack is upside down, in relation to how it sits on the motherboard. The flat metal pins that are sticking up, go down through holes in the motherboard, and are soldered to the motherboard, on the backside.
(The flat metal pin in the middle sticking up, goes to the center pin in the jack. One of the flat metal pins on the sides, goes to the metal shell inside the jack. The third flat metal pin on the side, is just soldered to the motherboard, and helps to give strength to hold the jack in place)
Sometimes these solder joints for those pins can be broken. They develop a crack in the solder joint.
In a case like this, just re-soldering the solder joint/s, puts the laptop back in business.
I posted all of this, in case this is the issue you are having.
The following is a link to a Maintenance and Service Guide, for the HP Pavilion dv6000. Don't let the name 'Guide' fool you. This is really an extensive Service Manual.
It tells you, and shows you how to disassemble the entire laptop down to just the bare motherboard in your hand. Also tells you and shows you how to remove and replace all the hardware components inside. It also has all the part numbers. It also has exploded illustrations of the entire laptop.
This is HP.com/Support>Manuals, and the page to download the manual I stated above,
Just go down to the blue ->
HP Pavilion dv6000 Notebook PC Maintenance and Service Guide <- , and click on it.
This is a PDF file you download. You have Adobe Reader on your computer. Adobe Reader uses PDF files.
After you copy and paste the link above into your address bar, press the Enter key.
For as much as 30 seconds, you may not see anything happening. The file is downloading, I assure you. The first page may pop-up after ten seconds. IF So, you should see a green Adobe download
bar below to the right. It will show the progress of the download. I suggest you let the file fully download, before you look through it. If you start looking through it before it is fully downloaded, you could break the download connection.
After it has fully downloaded, you can save it to your computer if you wish. This way you can have it to look at, anytime you want. You can also burn it to CD disk.
Just go up to the top headings, and click on the floppy disk icon. It is the second icon from the left.
Hovering your mouse cursor over it will briefly reveal, "Click to save this file to your computer or another location"
(IF you take the laptop apart, remove the battery and the AC adapter first. Also so I suggest using an ESD wrist strap. They are cheap, and help to insure that you relieve your body of Static electricity)
