DV9700 Windows 7 32bit Brightness & Driver

[Ushilives]

Hi there.

I installed Windows 7 32bit and have tried allsorts of Nvidia Graphics Drivers for it to display coloured lines down the screen once rebooted. I gave up and thought i would stick to the standard VGA graphics driver but i cannot adjust the brightness. I tried Windows XP and even though i didn't have the correct graphics driver i could at least change the brightness.

Please help someone!

Thanks.

Hi:

When the graphics driver is not installed, you cannot adjust the brightness.  It is stuck on maximum.

The only suggestion I can offer would be to install the Vista graphics driver.  That always works.

If you still get colored lines down the screen after you install the driver, then the nvidia GPU has overheated over time, and is damaged.

That happened a lot with the dv6000 and dv9000 model series.

You have to manually install the driver as follows...Run the driver.  You will most likely get an unsupported operating system error.

ftp://ftp.hp.com/pub/softpaq/sp38501-39000/sp38834.exe

Close out of any error windows.

Go to the device manager.  Click on the standard vga adapter needing the driver.

Click on the driver tab.  Click on Update Driver.

Select the browse my computer for driver software option, and browse to the driver folder that was created when you ran the file.

That folder will be located in C:\SWSetup\sp38834.

Make sure the Include Subfolders box is checked, and the driver should install.

Then restart the PC.

Thanks! It worked! It accepted the installation and rebooted, i spent over 10 hours trying to sort this out and it's finally fixed.

Do you know a good website to get any missing drivers for this laptop? I have 3 base system device missing, 1 coprocessor missing & 2 unknown devices.

[Paul_Tikkanen]

You're very welcome.

You need this driver for the coprocessor...

ftp://ftp.hp.com/pub/softpaq/sp37501-38000/sp37730.exe

You need this driver for the base system devices...

ftp://ftp.hp.com/pub/softpaq/sp37501-38000/sp37809.exe

I would need you to post the hardware ID's for the unknown devices, because there are too many devices that Windows labels as unknown for me to try and post drivers for those.

Use this guide for how to find the hardware ID for a device...

Thanks I can check out the hardware ID's a bit later and I'll send the relevant info.

Hi the hardware ID's are as follows:-

HDAUDIO\FUNC_02&VEN_14F1&DEV_5051&SUBSYS_103C30CF&REV_1000
HDAUDIO\FUNC_02&VEN_14F1&DEV_5051&SUBSYS_103C30CF

ACPI\HPQ0007

Hi:

I think the first one is the modem...

ftp://ftp.hp.com/pub/softpaq/sp37501-38000/sp37725.exe

The second one...see if this driver works for you...

ftp://ftp.hp.com/pub/softpaq/sp44501-45000/sp44777.exe

Thanks the drivers worked so now I have all of them. There's just one little issue I have still and that is the display, when I change the resolution to the highest and apply it seems fine but then when I reset it goes back to lowest resolution, I noticed in resolution settings it is on 1/2 multiple monitors and if I change it about sometimes it doesn't display a pic once rebooted. I've had a fiddle with Nvidia control panel for picture and same thing happens 🤔

You're very welcome.

Unfortunately, I don't have an answer for you regarding that problem.

You do know that you can go into the BIOS and adjust the amount of video memory, correct?

I think there are two memory levels you can select...64 MB and 128 MB.

Maybe you need to set the video memory to 128 MB.
