My laptop shuts down when it has to go into sleep mode, I already searched every energie save option, switched different HHDs, installed windows like 8 times. checked the bios and it got the newest version. I don't know what to do anymore. Hibernation mode works fine but when i want to let my laptop sleep, it completely shuts down. I ran different hardware tests but all say the HDD is fine and the RAM is fine. How can i fix this?
