Get onlineand got to www.google.com In the google search box type: "HPSupport" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operatingsystem when requested. Look for Manuals an see if any give you any instructions on taking the laptop apart.You can do it without a manual. Just have come small paper cups that you label to hold the screws and a digital camera to take photos.
Turn the laptop over and start removing screws from the bottom. Then remove the battery, the hard drive, the memory, the wireless card, the dvd drive. Look inside the battery case and there might be screws inside it to remove. There might also be some inside the hard drive or dvd case to remove. Take note of the screws that might have the icon of a keyboard beside them (these hold the keyboard in place).
After the screws and devices are removed from the back, turn the laptop over and remove the strip (be careful there might be a cable under the strip) that is just above the keybord (sometimes it might be attached as one big piece to the palmrest). One the strip is removed, remove the keyboard (be careful there is a cable under the keyboard). Next remove the LCD Screen by removing the screws that hold it at the corners and also pull the cables from the wifi and lcd cable. Afterwards remove the palmrest there will be cables attached to the palmrest. Once the palmrest is removed you can start removing screws that hold the motherboard to the bottom base, then lift out the motherboard.

I have a hp pavilion dv9000. and i need the screw for it.


Check out page 86 for the display schematics. Page 120 outlines the dis-assembly. Page 154 actually describes the screws of which you speak. You may be able to purchase them locally.

There is one screw on the bottom of the machine that removes the CD right above the memory cover. It may even have an icon of a CD for it. then it should slide out the side.

No Display


First make sure everything else is getting power and operating okay, and that it is only the LCD display that is non-functional.

If you get no video signal or power at all, even at boot time, you probably have a dislodged ribbon cabling or power connection. Usually when LCD monitors go bad they show colour banding or all white, etc., but usually continue getting power.

As a last resort, try disassembling the lower case (with the power disconnected and the battery out of course) to expose the LCD monitor mounts, and then following the wiring from the screen into the laptop and check for anything loose or disconnected. You could also have a loose ribbon cable going into the LCD array, which will require disassembling the LCD cowling and mounts.

If you are handy and comfortable with electrics and find nothing loose, put the battery in and test the power line going to the LCD backlight, which should be getting above 7V (I think). Below that and you either have a bad video controller or bad wiring/solder joints somewhere. Otherwise, if the unit has been dropped or had a hard life generally, it could also be the connections between the LCD connector bus on the monitor array and the array itself. As a last resort, try unplugging and reconnecting all ribbon and connector cables, cleaning the exposed brass coloured runners lightly with rubbing acohol or even a pencil eraser.

Good luck...
