Monitor problem with the HP pavilion dv6000 laptop

SOURCE: HP pavilion dv6000 ( intergrated microphone problem)

Go check in the control panel to see if the microphone is configured correctly.  Then check in skype to see if that is configured and try again.

SOURCE: no speaker sound (HP Pavilion dv6000)

there a loss connection in the speaker of your system. locate the loss connection and fix it. if hard for you fix then you should call the technician to fixed for you ..or either use external speaker so that you can hear sounds without using headset.

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,
http://h10025.www1.hp.com/ewfrf/wc/manualCategory?lc=en&dlc=en&cc=us&lang=en&product=1842155&

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)

SOURCE: I have a HP Pavilion dv6000 and the fan has started making noises

Its possible but it would require taking out all the screws from the bottom of the latop, taking out the keyboard and the screws from the top cover. Then disconnecting the ribbon for the mouse pad and any other plugs coming from the top cover. After you take off the top cover you'll expose where the fan is at and at that point you can clean it off. If it still makes weird sounds then the fan would need to be replaced.

HOW TO FIX YOUR DV6000/DV9000/DV2000
All the Problems described are Graphics Related..

Faulty Nvidia Chip..Both Intel And AMD Based Motherboards..Though More Common on the AMD..
The symptoms of the Laptop Powering on and Shutting Off Repeatedly..Or.. Powering On and Having No Video...Or... Power Strip Lights Up, Beeps,Shuts Down...Or..No Power At All...Or.. Intermittant Loss Of Wireless/Video Goes In And Out/Touchpad Slows and Freezes..
To Fix this issue, You will need to Reflow The Graphics Chip.
I will Explain In Full Detail As To The Correct Method Below....
HP DV6000/DV2000/DV9000 Compaq v2000 Video Chip Reflow Instructions
First Step Is Complete Disassembly Of All Parts And Components..
Remove RAM, Remove CPU, Of Course Remove Heatsink and Fan assembly.
Next Step is Insulating the Motherboard... You need to Protect The CPU area, The RAM area, Cover any plastic Plug ports.
Try to leave 1/4 inch area around the edge of the chip free of insulation.
To Insulate the Board.. I use thick pieces of Tin/Aluminum, you can fold up some aluminum foil (tin foil) About 4 folds thickness....
Now that you have your Motherboard Insulated... Make Sure There's Nothing Flamable Or Burnable Below the Motherboard... it will get quite hot underneath.
You will need a Heat Gun.. You can get one of these at your Local Home Improvement Store, they cost about $15 - $30.. You Will Use ONLY the LOW Heat Setting... I REPEAT..... USE ONLY THE LOW HEAT SETTING ....
Next You Will Need Some Coins.. Yes Coins..
8 Quarters and 2 Nickels... Put the 2 Nickels On the Bottom and Stack Quarters On Top...
Place The Stack Of 2 Nickels And 8 Quarters On Top Of The Graphics Chip...
The Reason for using the Coins: Using the coins serves a few purposes...
1) It Helps Transfers the heat Into The Chip More Evenly/Slowly
2) It Helps Hold The Heat Longer/Then Helps To Cool Slower
3) It Gives The Correct Amount Of Weight That Is Needed To Press The Chip

A Thing To Look Out For...
Hewlett Packard is nutorious for using the RED epoxy around the edge of the Graphics chip.. this epoxy is used to help secure the chip to the motherboard...
This is a process that is Hand Done at the Factory.. And Some Boards Will Have Only A Little Amount of this, Some Will Have Alot of it...And Some are Only Done On The Corner Edges....
If There Is Alot of This On Your Chip, You Might End Up Needing To Carefully (REAL CAREFULLY) Remove as much of this epoxy as able to....You can use a Razor Blade To Lightly Scrape This Off... DO NOT MISS AND SCRATCH THE MOTHERBOARD!!! Go SLOW...
Now Comes The Heating Of The Chip...
Start With The Heat Gun About 6 Inches Away From The Top Of The Quarter Stack..You want to be holding the gun at a 45% angle.. Aim the heat at the Edge of the chip, You Will Start Rotating Around the Chip- around the outer edge of the chip...then use tighter circles concentrating on the quarter stack, then after about 30-40 seconds, slowly move closer to the chip...
Never Move the Heat Gun Closer than the Top Of Your Coin Stack...Then Pull It Back And Slowly Repeat.. The Chip Needs To Get Hot Enough To Re-Melt The Solder Balls On The Underside Of The Graphics Chip Back Down To The Contact Pads On the Motherboard.. and this takes Quite Alot of heating to Do.... You Must Not OVERHEAT the CHip... It Is Best To Underheat it and have to Redo.. than to overheat.. It will cause the solder to break down and even crack/split.. causing failure forever...
This process will take about 3 minutes total.. Once you shut off the Heat Gun.. Leave The Stack of Coins On The Chip And Let Sit For Another 5 minutes..
Now Remove The Coins(carefull they might still be hot)
Remove All Insulation.. Reinstall RAM, CPU, Heatsink and FAN Assembly (and Of Course Thermal Pads or Paste.. Note:. If Paste Is Used.. It Must Be Silver Paste...
Now You Can Connect The Power Button Strip/ Video Cable And The DC Jack Cable.... And Plug In AC adapter .. You're Now Ready To Test For Solid Power and Video....
Upon Sucessful Chip Reflow/Rebake.... You Need To Go To The HP Website..( www.hp.com )..Click on SUPPORT AND DRIVERS, then select...DOWNLOAD DRIVERS AND SOFTWARE....Then either click the box to Auto-Detect System, Or Enter Your Make/Model Info, Once At The Page With All Of Your Drivers.... Choose The BIOS UPDATE Driver..
Choose The Newest Driver And Download/Install It... It Will Reboot The Laptop And Upon Rebooting, Your Fan Will Spin Faster And More Often Due To A Thermal Controller Update In The BIOS Update...
