Hi,
I've upgraded my Lenovo P500 to Windows 10 from Windows 8, I noticed that the brightness has become very low. Could anyone help me fixing this issue?

Microsoft added adaptive brightness to Windows 8 and 10. Most vendors disabled it in 8 (because it's annoying and the laptop vendor usually has their own auto brightness app). But if you upgraded to Windows 10, it's probably enabled again.

Same problem with my Lenovo P500. Accidentally found the fix with a normal boot, but power adapter UNPLUGGED, while holding shift-F12 down during boot.
