Display dim after sleep/hibernate


I have a HP Elitebook 840 G4 with windows 10 home upgraded to windows 10 pro. I get a very dim screen whenever I put laptop on sleep or hibernate , and the dimming did not respond to light adjustment. I have to re boot the computer for the normal lighting to be restored. I have upgraded all my drivers from HP. Tried disabling automatic display adjustment, Tried Power Management options , and so many other things from the past threads,All failed. Please advise.
