That's a good one .. have once had same issue some years ago, that I took it to my technician and he did exactly on the ram..
I trust myself all process stored in my memory.. see when you are creative person, impossibly is a very hard word to find in your dictionary, 😆😆..
So I recently had same issue, my laptop went off for completely few months, few days back it done on me I can try to fix it myself DIY😄. LOOSED the ram space and remove one of the two ram in it, I on the laptop and immediately it on.. I was happy... Creativity moves far beyond craft .. great job
