Hi Mary. I have my laptop over one year, and i have been using it the same way as i did previously. This is an issue that i am facing in the last few months, so i did not have this issue before. I usually put my laptop on sleep mode when i am doing a break from it. and then i try to come back to use it, and i face this issue. I do a brief press of the power button, as i used to do before, and nothing happens, even if i wait for few minutes. So, today i just enabled the hibernate option, since before it was disabled, and my settings in my power plan is to never hibernate on battery or in-charge. So i would say it is not a case of the computer hibernating, right?
