** Description changed: What happens: Under Ubuntu 12.04, the system's power consumption is around 32 Watts idle, which is unbelievably high compared to the 12 Watts consumed by Ubuntu 10.04. I believe this could be a kernel problem. What should happen: The system's total consumption should be around 12 Watts. Software: - Ubuntu 12.04 LTS - fresh install Kernels I've tested are all affected: - 3.1.5 - 3.2.0 - 3.2.5 - 3.3.3 + - 3.3.4 - 3.4.0-rc4 Hardware: - HP nc6320 - Intel Core Duo T2300 - Intel Graphics 945GM + + The bug is also present on the following hardware: + - ASUS U24E + - Intel Core i7-2640M CPU @ 2.80 GHz (Sandy Bridge) + - Integrated Intel HD Graphics 3000
