Laptop is under 1year and under warrantee. So many times, I see Pre-Boot diagnostic error 0712: Fan is not working. Why would it come? I usually see this when I start it in morning which means for whole night long, laptop was idle. I am not a heavy user even though SPEC is quite high. I feel bad to see such problems after paying cost of high-end but underused laptop. Few months back laptop was completely out of action because mouse track pad was not responding, thankfully it was under warrantee and mouse pad got replaced. I need to get this Fan problem sorted too.
