I have a Dell Vostro 3500 laptop with Windows 7. I’m a computer professional with decades of experience but I don’t know the answer to this question. I left my laptop running when I left the house, Firefox was open. I came back <2 hours later and all the tiny light were off. It was still plugged into power. I’m sure of these facts. When I booted it booted normally without any error messages. I have had a dog unplug the power more than once, it is configured to sleep or hibernate within minutes. If Gotradio is playing it will run the battery dead first, then hibernate. Neither happened today. The battery was 100%. I checked the event view, nothing. There is a 5 minute time to Lock the screen. I left it unlocked. Could it have crashed? Keep in mind it booted normally.
My question is this: Was it a computer error or crash? Or did a human shut it down after I left? This issue here is Lying.
Let me know if you have any questions?
