Hi- Could you please post some screenshots? You measured that temp (48C) using which program? Please try and use RealTemp (google it) or CoreTemp (again google) and report back. Karan The laptop is hardly a week old. The BIOS is A10 version. How do I check if the heatsink is seated properly? Wait for the engineer to come to my place and do a diagnostic? Fans are fully operational... thats for sure.
