How to Improve the Display’s Brightness Sensitivity in Vostro V131?

In many ways, the

notebook is quite superior to its predecessor, the V130. Especially considering the battery life, where V130 had a non-removable battery plus the battery life was also quite short but V131 has a good battery life (and it’s removable as well).However, in order to reduce power consumption, when running in battery, the built in GPU (Intel HD 3000) applies few optimizations of its own, thus the sensitivity of the brightness of the LED display is somewhat aggressively reduced. For instance, when switching from darker images to lighter ones, the LED display takes few seconds to lighten up properly (vise versa).This is quite irritating while watching videos too, as when switching to a “bright” scene from a darker one, it takes few seconds to lighten up. And also when viewing darker images or videos, sometimes it’s too darkish as well :).But luckily we can easily fix it using the Intel Graphics configuration window. However, this might reduce your battery life a bit, so consider creating a “Profile” (or you can manually changes the settings using the settings window), so you could easily switch between the customized configuration and the default settings with ease, whenever you want.I’m using Windows 7 (came pre-installed with it).Okay, let’s do it …1. First right click on your desktop and from the menu choose: “Graphics Properties…” as shown below (make sure that you’re running using the battery, otherwise you cannot test if its working or not).2. Now this should open a window similar to the below one. But depending on your previous settings, after the above first step, it might take you to the below third (3) step directly.Anyhow, if you get the below window, then choose either “Advanced” or “Basic Mode” and click “OK”.3. Now this should open the Intel HD 3000 GPU’s configuration window as shown below.4. Now from the left side, click on the “Power” button.5. Once inside of that window, from its upper right corner, make sure the “On Battery” option is selected.6. Now from that same window, under the sub heading “Power Plans”, choose “Maximum Performance” by clicking on it.7. And in the next step, in the same window, under the third sub heading “Power Conservation Features”, make sure you’ve enabled (applied a check mark) “Display Power Settings Technology”.Under that you’ll see a slider and it by default should be located closer to the right edge (close to “Maximum Battery Life” option).This is what forces the GPU to lower the brightness “sensitivity” thus creating this anomaly ;-).Now just move that slider to the left edge (“Maximum Quality”), then click on the “Apply” button and when asked, choose “OK”.Now, wait for few seconds, and you should immediately see the brightness goes up and it’ll stay up and when done, click on the “OK” button at the bottom to close the window. That’s it!.If you don’t want the brightness sensitivity to be too aggressive, then you can test and achieve your preferred level by moving the slider slightly towards the left corner and clicking on the ‘apply’ button.But as said before, this will shorten your battery life a bit, so when you don’t really need the best possible picture quality, you can follow the above steps and move that slider towards the “Maximum Battery Life” option to disable or reduce the brightness levels.This actually should work for almost all the Intel HD 3000 based GPU’s if you’re having the same issue, not just the Dell Vostro V131. Good luck.Related Posts
