I have recently installed windows 8.1 and its working fine. but the brightness was not working at all. then i did the following to find a solution..
- I opened the device manager and click on the display adapter.
- I click on update driver option.
- then I click on the 2nd option "brows my computer for driver software"
- I click on "let me pick from the list of device drivers"
- I select 'microsoft basic display adapter" ( as it was the only available driver) and click on next...
as it was updated but still the brightness is not working.. any solution please???????
