I am looking to purchase a new laptop in the near future. I currently have a Lenovo Thinkpad S431 and it has been great. They told me it wouldnt be able to run AutoCAD efficiently, but it has had no problems with it. Only issue I have had with it is overheating when doing more than using the internet. This is something I would like to improve with my next laptop. I am thinking it is related to the CPU? Any specific or general recommendations would be appreciated.
