Hi everybody, I need your help. I have a Z Book that won't come out of hibernation. Also if it's turned off for a while it won't start up. When you take out the battery and put it back in turns on. Have you ever encountered same problem? Problem is because I don't know if its software or hardware problem. What I've already tried is power setttings in windows, updating Bios , new battery, nothing helps... Thank you for your answers.
