After screen replacement, brightness cannot be changed to save power

After replacing the LCD en digitizer screen on my Lenovo Yoga Pro 1370, the power saver does not adjust the brightness anymore. The brightness control in Windows 10 is also greyed out so I cannot adjust in manually either. I have reinstalled the drivers but this hasn't resolved the issue. Does anybody know what could be the issue?

Is this a good question?

Hi,

Can you try a system restore to just before you replaced the screen and see if your brightness controls work again? Alternatively here is a link which allows you to run diagnostics on your laptop. Click on diagnostics. http://support.lenovo.com/au/en/products...
