#Sony vaio brightness control not working windows 8.1 drivers
Here's a search of Intel HD Graphics 4000 drivers from the Microsoft Update Catalog site. Unfortunately there are some other limitations when upgrading to Windows 10 on Sony Vaio laptops as they have mentioned here (and Sony has not yet released any Win10 compatible drivers & software until either late October or mid-November of 2015).Īnd Lenovo has NOT tested the Ideapad P400 touch for Windows 10 compatibility as mentioned here (if your Lenovo computer is not listed there, then Lenovo does not support the Win10 OS upgrade on older non-supported computers). Choose "display adapters" as device type and select microsoft basic display adapter. Select display adapters and right-click on intel hd graphics 4000, then select update driver > browse my computer for driver software > let me pick from a list of device drivers on my computer. Open device manager (search for it or right-click start). (i have the intel hd 4000 graphics card on a lenovo p400 touch).Īnyway i tried a bunch of methods i saw in other forums and finally came across something that worked for me. They released a beta but it doesn't work well. I searched online and it seems that a windows 10 compatible driver for my graphics card hasn't been released. The day i upgraded to windows 10, my screen went very dim, and i could not adjust it. Quote=ivandavid1 313636]i had the same problem.
Manually closed the laptop down but when i started it up again the screen was bright and readable though the graphics are slightly squashed vertically. Screen went totally black after i made the switch. I tried many other options for the post 10 dim screen on my sony vaio laptop with intel graphics but only this one seems to have worked.
