view story

http://ubuntuforums.org – Hi guys, I am new to this forum as well as to Linux. (former Windows user...). Im using Ubuntu 12.10 for 64-bit. I have a brand new Dell Inspiron 15 R laptop with hybrid graphics card, Intel® Core™ i5-3317U CPU @ 1.70GHz × 4 with AMD (AMD Radeon dont know exact card name). My trouble is that when I charge my laptop the fan is noisy. I have installed Jupiter and set it to power savings mode. When I remove the charger the fan noise stops. Temps when I type "sensors" in terminal are as follows: coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +54.0°C (high = +87.0° (Hardware)
