I also have the same problem as other have posted. Definitely a hardware issue. The last thing I did prior to the issue was leaving was disabling sleep mode due to a download. The issue is still visible in the BIOS as well. I've tried all options to rectify (pin in the hole etc). Interestingly, the fan doesn't seem to work at the moment and the issue comes and goes. Right now, as I type, the issue is barely noticeable but if I open the start menu it is very noticeable. My product is registered and I've tried to follow the options to getting my laptop repaired but the Acer website keeps stating that my S/N SNID isn't valid. How do I get this laptop replaced? It's only 5 months old. Not good Acer.
