It happened to me once, I hadn't realized that I would have to put the laptop to charge so when the message came that it was turning off I didn't even have time to plug it in.
Result, what I had done, I lost everything... I thought that everything I was writing in the article could be saved, but it wasn't. Very frustrating...
This is what I do as a "draft" in Word and then send it to the blog page. This way I don't run the risk of losing everything.
That's what I used to do you know, but haven't in years cause I usually just get it posted immediately. I saved the draft cause I had to walk away for a few minutes and didn't want to lose it, welp lol
