Graphics card problems on Hp pavilion dv6000-6500 laptop

[gomenlo]

I have an old HP laptop, the Hp pavilion dv6000 (or dv6500), which has a problem with the graphics card; the graphics do not display correctly. The first time this happened was before I installed Linux when the laptop had Windows 10, but it did not happen again until I installed Ubuntu MATE 22.04.3 (for the first time). When I installed Ubuntu MATE 22.04.3 (for the first time), the graphics did not display correctly, and sometimes the screen would freeze, but not due to RAM exhaustion. After a few days, I installed Windows 10 and left the laptop on a shelf for almost two years. This year, when I continued my efforts, I installed the Nvidia driver on Windows 10, and when the laptop booted into Windows, the graphics displayed correctly but often at the lowest resolution, without the ability to change it. When I installed Ubuntu MATE 22.04.3 (for the second time), I chose to install graphics card drivers via Wi-Fi. The problem was solved until the next day when the graphics did not display correctly again, and most of the time, the problem is not fixed by restarting; the screen settings show a resolution of 800p*600p and do not allow me to change it. Even during the post (where the manufacturer’s logo appears), the graphics do not display correctly. The laptop has 2GB RAM, an SSD disk (we replaced an HDD it had), an Intel Core 2 Duo T7250 processor, and an Nvidia GeForce 8400m gs graphics card. Also, the processor, before I installed Ubuntu MATE, when it had Windows 10, had temperatures up to 94 degrees Celsius (we had dusted the laptop a few years ago), while now with Ubuntu MATE 22.04.3, the temperature has not exceeded 67 degrees Celsius; the laptop had overheating issues for years. The battery broke, and I removed it. For several years now, we have been powering it with a charger that is not the original (19V). Apart from the graphics card, the rest of the hardware works normally. How can I fix the laptop?

For best results when running W10, manually install the Vista Nvidia graphics driver from your notebook's support page:

HP Pavilion dv6500 Entertainment Notebook PC series Software and Driver Details

Download and run the above driver.

You will most likely get an unsupported operating system error.

Close out of any error windows.

Go to the device manager.

Click to expand the Display Adapters device manager category.

Click on the Microsoft Basic display adapter listed there.

Click on the Driver tab.  Click on Update driver.

Select the 'Browse my computer for drivers' option and browse to the driver folder that was created when you ran the file.

That folder will be located in C:\SWSetup\sp42635.

Make sure that the Include subfolders box is checked and the driver should install.

Then restart the PC.
