I just got my new laptop Dell Vostro 3560
The issues is that bottom center portion is getting heated. suspected some issue with HDD. So installed crystal Disk info and saw hdd temperature getting up to 47 C without any activity on laptop.
Called up dell support they ran a hardware diagnostics and refuse to listen to any issue if diagnostic is not detecting anything.On the inside, the Vostro 3560 can have either an Intel Core i3 or a Core i7 third generation processor
