Freezes usually once or twice a day and have to unplug. No black or blue screen, just same screen I was on, but cursor will not move. Maybe memory problem( I have 2 GIG memory which is max available for this model) but I think more likely is overheating. I installed SpeedFan. However, I am not sure how to interpret SpeedFan results,but think problem is in first of these numbersGPU 96 C Temp1 85 C Core 80C (per Speed Fan as I write this message) Does this model have history of overheating? Is there anything I can do ? Thanks
I agree about the over heating. I have to take my laptop apart about once a year and clean the dust out of it. When you do this, you have to remove the fan and inspect the shroud (once I had a dust ball that had obviously been rolling around and around in the shroud. It finally got do big that it stopped the fan). Also most of these laptops have an outlet that is vented. After all, if it wasn't a kid would stick something in it or a bug would crawl in it or whatever. The last time I cleaned mine, a layer of dust had formed over this out-vent. It formed so neat and perfect that at first I didn't know what I was looking at. It looked exactly like a manufactured filter. And then it hit me - "THERE AINT NO FILTERS, ANYWHERE!" lol........ There are in-vents all around. But only one outvent. If it gets stopped up, it doesn't matter what kind of fan you have. Your computer is going to overheat.
If you find that your out-vent is not stopped up, a good experiment would be to find four things to use as spacers and open up your computer. Block the top half (keypad-screen) up and watch what it does when running open.
Another thing that just came to mind - If your computer is overheating, you should hear your fan laboring (running hard and fast) way too much. If it isn't, maybe it's the fan control circuit/program. Under normal conditions, after start-up, it should slow down and become almost inaudible.
I hope you'll let me know what you discover.

You can make an alternate filter that reduces some of the lint fibers. On a DV6000 & DV9000 as well as the F500/700. a used drier sheet, under the fan, can reduce the amount of fibers and dander that is drawn in. Though the airflow will be somewhat reduced.
Another alternative is to never use the DV series on bed, blanket, or on carpeted floors. and to get some rubber bumpers (at Dollar Store) to raise the rear of the unit some.

I believe it's the DC Power Jack, that is causing the problems. This jack is where you plug your AC adapter into the laptop. (Power adapter)
There can be many unseen issues with the jack, or it's mounting on the motherboard, that cannot be seen from the outside of the laptop.
The jack itself, is a small rectangular object, and the inside body of this jack is made of plastic. Then there is a rectangular metal shell, that surrounds the plastic inner body.
Let me show you,
http://www.megaemarket.com/dcpojacoforh6.html
(You can click on the photo to enlarge it. It isn't the clearest example of an image, when enlarged, but gives you more of an idea of what the component structure is)
The thick round metal pin in the middle of the jack, is the Positive connection. As you can see from the rear view, the pin attaches in the middle of that plastic inner body. Also looking at this view, the
L shaped flat metal prong, that is connected to this metal pin, is soldered to the motherboard. (It looks just like the L shaped prongs on the side, but you are looking at a rear view of it, not a side view)
The metal 'frame' that surrounds the plastic inner body, connects to the round outside shell, that surrounds the thick metal pin. To help explain further, the outside part of your AC adapter plug, fits tight up against this round outside shell, that I'm trying to explain.
This shell is the Negative connection.
Looking at the back view, the two flat L shaped metal prongs sticking up, are soldered to the motherboard.
I felt this explanation would help give you a better grasp, of what I'm about to explain.
Perhaps this jack is damaged.
Perhaps the thick metal pin's attachment to the inner plastic body, has broken loose, and has now cracked the solder joint for the L shaped prong on the back. (Solder joint to motherboard)
Perhaps the outside metal frame L shaped prongs, have had their solder joints cracked.
If a solder joint is cracked, (Broken), there may be no connection, or an intermittent one.
One more item. Some laptop motherboards had a bad design. Let me explain with this crude example.
For this example, think of the laptop motherboard, as being a 1 foot square. (It isn't. It's irregular shaped)
Now along one edge, attach a 2 inch square. (It's all one piece though) In this 2 inch 'Peninsula', attach the DC Power Jack.
Sometimes this 'Peninsula' can crack, and break away from the main body of the motherboard. If it does, it can break circuit traces.
Circuit traces can be thought of as very flat, thin, copper wires.
These traces connect the power jack to a circuit, that charges the battery, and senses when the battery is fully charged. If there is a problem here, the sensor circuit will read faulty information.
It will sense that the battery is fully charged when it isn't, and also sense that there is no AC adapter plugged in, therefore it will result to using battery power. (Battery isn't charged. Power fades out quickly)

Sounds like the harddrive went bad.
Some people call it the click of death.
Put the laptop to your ear near the harddrive and you will hear the clicking coming from there.
Good news is that it's easy enough to change the harddrive.
Bad news is you lose all your data to this point.
I hope this helps and i'm sorry that happend to you.

it's windows problem
format your system or reinstall your OS
may be virus on your system

If your 9000 is under two years old, you should contact HP customer care and have unit serviced under warranty.
HP has had allot of problems with the 6000 and 9000 units and in response has offered an additional year from date of purchase.
Its worth a shut. Doesn't cost a dime.
Hope this information has helped you.

Sounds like you need to take it in for repairs, clean outs and/or replacements.
This product is known for it's heating issue and power consumption. Maybe the fan is starting to wear out and it's affecting the rest of the system. I would suggest checking the warranty on the system, if it is no longer valid, then I would look for a local tech in the newspaper.
