HP Pavillion dv6000 laptop computer will not power on

My HP Pavillion dv6000 laptop computer (s/n CNF72132WJ, p/n GH783EA#ABU) will not power on - it gives 1 long beep followed by 3 short beeps and then does nothing. I've been told that the problem is the NVIDIA graphics card but am unable to find this part in the HP Parts Store. Is the NVIDIA graphics card a separate purchasable item for an HP Pavillion dv6000 laptop computer or is it integrated into the system board (p/n 443774-001)?
Where in the UK can I purchase either a replacement NVIDIA graphics card or a replacement system board (p/n 443774-001)?
Thank you in advance for any help you can give me with this problem.

The Nvidia graphics card is soldered on to the motherboard and you need to replace motherboard for the Notebook to work according to your diagnosis.
The Part# - 443774-001 is Out of stock and curent not available in HP Parts store however I just did a search for you on Ebay UK website and was able to find it in search results over here

Ouch, not much more you can do, I think you'll have to have it looked at.

HP Pavilion dv6000 will not power up.

I have had an HP Pavillion dv6000 for a few years, and suddenly, it will not power up at all. I can not determine that anything at all happens when I press the power button. What's weird is that when I connect the power, the AC LED (the one with the lightning bolt above it) lights, and stays lit for 30 seconds, and then turns off. During that time, and thereafter, the power light will not come on at all, and the computer will not power up. I have tried removing the battery and power cord and holding the power button for 45 seconds, multiple times, but nothing seems to work. I hope you can offer some advice on things to try.
Thanks,
Zach

Well, I've had the problem for a while and was just looking around to see if anyone has had any success stories.
I will tell you how I get mine up and running, but first some background. I was gifted this computer DOA and asked to retrieve data which I was able to do but in monkeying around, I discovered a "fix".
You see, I live in an area where we occassionally lose power for a day or two or three so the weakened battery never outlasts the outage. That's when the unit becomes unstartable.
Now the fix:
It is a variation of all the other suggestions about undoing the power cord and disconnecting the battery but here's the twist: After removing the battery and power cord, wrap your laptop in one then another plastic shopping bag and place it in the freezer for about an hour or two. Now, when you take out your shivering laptop, plug in the power cord and fire her up. It has nearly always started for me after this trial by cold but once or twice it needed more chillin'. Once it is started, insert the battery. I've never had any issues with this sequence.
You will have a lot of condensate on the screen but gently wipe it up with an absorbent cloth and let the rest of air dry as you let it run.
As long as I leave the computer plugged in and not reliant on the battery, it has never died on me.
Hope this helps!

Need Help HP DM3 (DM3-1130us) Laptop will not power on. No power at all except for light on a/c jack

Hello, I need some help.
I have a HP DM3-1130us Laptop that will not power on at all.
the only thing that happens when I plug it in is the power jack lights up.
When the power button is used absolutely nothing happens.
No power, no fans, no leds, no on/off cycles, no beebs, absolutely nothing
just the light by the power jack that says the cord is plugged in.
The laptop has Windows 7, 320gb hdd, 4gb ram.
I have tried new power adapter and still nothing.
I have taken the battery out and tried and nothing.
I've tried the option where you take the battery out and hold the power and nothing.
I have tried with different hard drive and no hard drive and nothing.
I have tried reseating the ram and tried new ram modules still nothing.
So I am kind of stumped on what to do, the laptop will just not turn on.
Its not under warranty anymore so cant send it off.
It has not been exposed to any elements(extreme heat or water).
and its never been dropped or anthing.
Im kind of wondering maybe the power button board its self is bad?
If feels fine, its not loose or anything but could it
have just stopped working? for those who are not familiar with this model.
the power button is on the side and is a kind of drag and release button.
Its also on the same board with the Wifi button and 2 Usb ports.
But Im wondering before I buy a new one if this is what it could be.
Or could the motherboard its self be bad?
But even if the motherboard is bad would it still power up
just not post?
Also does anyone know of any other way to try to power this laptop up
without using the slide button. I mean kind of like off a Dv6000 you can power the laptop on by using the Quicklaunch buttons on top but this laptop does not have those.
If anyone can provide any information I would appreciate it.
Thank you.

Hey Tyler,
Unfortunately it is difficult to troubleshoot this type of issue. The majority of the time when the computer wont power on with the same symptoms you described, the power supply board is faulty. Most of the time if the motherboard is bad it should at least turn on or so some signs of life. Like I said, this is most of the time. Sometimes it could do exactly what your experiencing. I would suspect the power supply board has failed since you are not receiving any sort of lights, sounds, etc.
You could check the motherboard for swollen capacitors or loose solder joints but sometimes you wont be able to find anything.
I hope this helps answers your questions,
Sean

Acer Aspire V5-571 will not power on

Apologies - just posted this question in Welcome Forum by mistake.Computer will not power on, was working perfectly last night when I shut down. Have tried all suggestions in Knowledge Base with no success. Any help very much appreciated. Thanks in advance.

I have had this problem twice now. My system is working just fine. I power it down and take it to work or home. I get to my destination and plug in my system and i get NO lights of any kind. It will not power up at all. I get NOTHING. My laptop is all of a month old. I pull out my screwdriver and take off the bottom cover. I check connections etc. Everthing is tight and clean. BUT note that I have touched several metal components. Did I just ground out any stray charges? I don't know. But Now after doing nothing more then looking and touching I put the case back together. Turn if over and plug everythign back in again and NOW it powers up. The second time same thing only this time it gets to the Acer screen and nothing. I power off/on and try again. Acer screen. After 2 cycles of this I swap out the power block (19V @ 3.42A acer just like the original). After 2 more cycles I swap back to the original. I try #5 and i'm getting ready to power off again when I get the floting balls wait sign and I wait.... now up until now boot up on windows 8 has always been less then a minute. This time its taken like 6 minutes to boot up. NOTE It updated to 8.1 last thursday (I HATE auto updating! it is now turned off!). So any ideas here? is this a static buildup issue? Is this a design issue? Power board or plug issue? What is the problem here Acer. I LOVE my 1st acer aspire 5210z until the screen died. So I buy the awesome new one and ACER HELP!!!!

Compaq CQ62z-200 will not power on

I have a Compaq CQ62z-200 laptop which will not power on. I have tried removing the battery and powering it on using only AC Power and I can get the PC to turn on and go to the red Compaq screen but it then powers off in less than a second. When it does power on briefly it makes a click before shutting down. Any idea as to what this could be and how to repair it?

Unless you know how to replace the motherboard and can save the labort charges I would say it is just time to get a new laptop. With new ones at record low prices and considering how much better laptops have gotten in the last 3 years, the decision seems easy.

IBook will not power on suddenly, weird noise from CD drive

Hello!
My iBook G4 (800 MHz, 512MB RAM) was working fine yesterday, then suddenly this morning it wouldn't power on. When I press the power button, I can hear the hard drive start spinning, but there is no chime and no screen. It just stays black.
The optical drive also makes a strange noise. Usually when you start it up, you can hear the CD drive make noise like it does when it ejects a CD. But now, it sounds very strange. If I had to guess, I would say that it sounds like it is going out.
I have tried to start without the battery and have reset the PRAM and PMU multiple times without any luck. Any thoughts would be appreciated.

gjortega ,
Here's the troublshooting guide from the service manual:
"Startup
The computer will not power on
1. Remove any connected peripherals.
2. Try known-good power outlet.
3. Try known-good power adapter and power cord.
4. Remove battery.
5. Reset the power manager by pressing the key combination Control-Option-Shiftpower.
Warning: Make sure you do not hold down the "fn" key when resetting the
power manager.
Warning: Resetting the power manager will permanently remove a RAM disk, if
present, and all of its contents. You will also need to reset the date and time
(using the Date & Time control panel).
6. Disconnect internal keyboard completely. Inspect connectors. Restart with keyboard
disconnected.
7. Remove any additional RAM and AirPort Extreme Card.
8. Try known-good DC board.
9. Verify power button is connected properly to logic board, if power button is not
functioning correctly or damaged, replace the top case.
10. Replace logic board."
Now that #10 would be about U28 or the GPU. U28 is that site I sent you. The GPU sits under the option-Apple key and you can put pressure on it from underneath that area. There is a large heat spreader that sits on top so you have to come from underneath.

Hello, My white McBook (2008 or 2009) recently stopped turning on. When I hook up the Magsafe power adapter, the light shows green, but the computer will not turn on, or make a sound. I've tried the re-boot option, but nothing works. Please advise!

Hello,
My white McBook (2008 or 2009) recently stopped turning on. When I hook up the Magsafe power adapter, the light shows green, but the computer will not turn on, or make a sound. I've tried the re-boot option, but nothing works. I first thought I needed a new battery because the lights at the back are all off, but shouldn't the computer turn on once the power adapter is hooked up and the light on the Magsafe adapter shows green? I'm a computer doofus, so please be kind. Please advise! Thanks in advance.

I recently bought a new laptop because my old one crashed. The only backup I had for my music was on my ipod. My new computer will not recognize the ipods music and I can't transfer anything. What do I do???

I recently bought a new laptop because my old one crashed. The only backup I had for my music was on my ipod. My new computer will not recognize the ipods music and I can't transfer anything. It keeps asking me to sync the ipod to this computer, but I'm scared to lose all my music. I want to transfer some of the music onto my iphone but I can't. I'm very frustrated and wish I knew more about computers at the moment!?!? What do I do???

You will need the help of some sort of 3rd party software to help you copy the content from your Shuffle back to your PC. Once you have done that, you can reimport this music into iTunes and configure it to sync to your new Shuffle.

My ipad will not power on after update. I have tried connecting to computer which doesn't recognize it. I have pushed top and circle buttons at same time. It had a battery charge before it died. I tried to stop the upload and am afraid it 'crashed'

My first genteration ipad will not power on after update. I have tried connecting to the authorized computer which won't recognize it - does not acknowledge a device is plugged in. I have pushed top and circle buttons at same time. It had a battery charge before it died. I tried to stop the upload midway and am afraid it 'crashed'

Try putting it into recovery mode.
Connect iPad to your computer via USB while it's turned on.
Open iTunes
Hold the iPad's Sleep/Wake switch (power button on the top of the iPad) down until the "power off" slider appears.
Power off the iPad completely (wait for the progress spinner to disappear).
Hold the Sleep/Wake switch AND the Home button down for a full 10 seconds.
After 10 seconds (the second time you'll see the Apple logo on the screen) release the Sleep/Wake switch while still holding the Home button.
Continue to hold the Home button for another 10 seconds until the USB connection image appears on the iPad's screen, then release the Home button.
A pop-up message will appear on iTunes saying it has detected an iPad in recovery mode, you must restore...
Click on the "Restore" button and the process will begin.

Computer doesn't recoginize iPod nano 7th Generation and it will not power on

My iPod Nano 7th Generation was working I plug it inot the computer and computer would not recoginize it and now it will not power up.

Try:
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
