Being a person who enjoys keeping up with the latest features of products and frequently updates software, I installed an update for the HP Elitebook 8730w’s Nvidia Quadro FX3700M graphics card via Windows Update yesterday. It was called “nVidia – Display – FX3700M”… upon restart, I found the screen brightness of the HP Elitebook 8730w was about 10 to 15% dimmer than usual and the colors became out of whack, even with the brightness cranked up to the max and ambient light sensor off. Only when I plugged the AC adapter in, the brightness and colors went up to normal for about 5 seconds, then it was back down AGAIN! The notebook also no longer detected the display as a DreamColor display and the “Sharpness” option (see the screenshot above) had disappeared from the Nvidia Graphics control panel. I almost panicked as there was no way to remove the update, even via the Windows Update ‘remove updates’ panel.
In the end, I uninstalled all the Nvidia drivers and downloaded the one from HP’s website. Evidently, it’s not the latest driver but at least brightness is back to normal again, colors are accurate again, and the notebook detects the DreamColor display and show the Sharpness option again. Well, HP Elitebook 8730w users, you’ve been warned. If you still feel like installing that update, do it at your own risk!
