When you start holding down the shift key, that is safe mode. Are you getting the dim screen in a normal boot up? What is your operating system? Try both aSMC and Pram reset.https://support.apple.com/en-us/HT201295 https://support.apple.com/en-us/HT2040 You could also try toggling the F 2 key for brightness.
