Hello,

I have recently bought dell 14z 5423 with service tag [Amin Note: Service Tag Edited per TOU policy].....I want to know WHAT SHOULD BE ITS OPTIMUM OPERATING TEMPERATURE,,it is operating at temperature of about 50 degree C at small load..............is this OK??.......also I upgraded the BIOS to A13 (In the dell site, the upgrade for BIOS was not given under "filtered drivers for your service tag"...but was given under "all related drivers for your product")...........was this BIOS upgrade unnecessary? Will it create any problem?.....Or Is it OK?

Thanks
