I am a AD designer. Sometimes I should take my dell 15R to my customer office.
I use CS4 to edit and show the ad photo for my customer, after using for 30 minutes the laptop become very hot and battery only can last 1 hours. I Also bought a battery replacement from starmall , why the CS4 so hot, I always must close the CS4 when It exhaust too many CPU and reopen it. Is there any better if I upgrade to CS5?
If this did not happen when you first got the unit and you have used it a lot it might need a cleaning to provide better airflow, I assume you always make sure that you are not obstructing the airflow by putting on a soft or padded surface. Generally upgrading adds more features which require more code which would require more CPU power. I do not know if this is true in Photoshop as this forum and my experience is with Premiere. Maybe you need a laptop cooler!
