Notebook not displaying a single thing

Go to the hp website www.hp.com on the dv4000 computer. Enter dv4000 and then the sub model number on the label from the bottom of the laptop. Then allow the installation of the driver scanner from HP to download/install (press OK to continue to install and let it scan the unit for needed driver updates), then go to the Audio section of the then listed drivers. after entering the operating system installed (see Start>Control Panel>System>General tab for installed OS info), and install that latest Audio driver package update. I would also personally install all the other required driver(s) & the latest BIOS update listed there also myself. IMPORTANT: When installing the latest released (or highest #'d) BIOS update (the BIOS simply allows all the hardware to work together w/ the OS), make sure the computer is plugged in, and do not interrupt the install process or restart/shut down the unit until the program does it for you. (If you have never "flashed a BIOS" before...Have a techie friend do it for you instead, after downloading the proper file/& flash utility...Real patience pays here, or you can flat turn a motherboard into a useless doorstop). It can always be reflashed by the manufacturer (or others), though even if a BIOS Flash is messed up.

Free Belarc Advisor (www.belarc.com) if installed and run will inventory all your hardware & software if you have any questions about whether a specific driver listed matches your specific hardware concerning that dv4000.

There were a few HP dv series laptop motherboards that had a problem holding both Video & Audio drivers (install 1 and the other would blow out & get corrupted), install the other and just the opposite...They had a class action settlement that was only 90 days or 6 months long and really screwed many of us over in the process. If there is a choice between the dv4, dv6, & dv7 series I always pick the dv7 series to recommend to & for my customers.

You need to make the USB first boot in BIOS, or use the boot menu selection. Both are noted during start up.

Then there is the issue of the USB install is it bootable? You need software like Novicorp to make an USB Installer. gl

download from hp this driver to your my_documents folder and install the software for the driver... then restart your computer

does this work... solution

or goto start > control panel > system > device manager show up

look at your audio device in the list... does it have a yellow explaination point.. no driver installe


a red mark mean on the audio device means that the sound chip is bad... and you need to ship the board to a repair shop ... or rma the laptop for repair if still under warranty

also go under the bios to be sure the sound is turned on .. there sometimes is an option to turn off the sound functionality

Flash Recovery-Config Some motherboard makers incorporate a flash recovery-config jumper or boot block recovery jumper on their motherboards. This can often be used to recover from a bad or failed flash. On most machines a small segment of the flash ROM does not get overwritten when you perform a normal flash update. This small portion of code contains a basic boot block which can enable the machine to reload another BIOS from floppy disk.
If you have a laptop or desktop without a floppy. You can either fit a floppy in the conventional manner or in some cases a USB floppy or CD-ROM can be used.

Have you changed the resolution?
Go to control panel, display, settings, and make sure the resolution is set to more. Click on the advanced button and choose the tab for graphics or the graphics controller, choose properties, and adjust the screen area.
Please also consult this link recommended setting for HP notebooks. (click here)
If that doesn't do it, is there a possibility that the wrong driver has been installed. You can check the original product specs at hp.

do you have an external monitor that you can attach to the vga plug on back of laptop.

you can reset the bios by taking out the battery on the motherboard (looks like a watch battery) leave it out for a few minutes then replace it again.

Have you tried changing the display.
Right click the desktop, go to properties or personalize if using vista, and check that the display properties is set correctly for your graphics card. Change the size of the display from in here.

I hopet this helps.
