USB suspend/resume in linux

2006-10-12 Thread Kaburlasos, Nikos
Does anyone know whether the linux USB drivers support the suspend feature on idle USB ports (i.e. the port has been idle for sometime and so the driver transitions it in to a low-power 'suspend' state) while the system is active and in S0 state? As far as I know, Windows don't support that, I was

Thanks. But is 80C safe for a CPU? As I mentioned, 70C is considered dangerous for an Opteron chip. What type of temperatures can the Turions and the C2D support? On Fri, 13 Oct 2006 05:53:39 +0100, "Matthew Garrett" <[EMAIL PROTECTED]> said: > On Thu, Oct 12, 2006 at 09:41:15PM -0700, Mathew B

Thanks Matthew. Just out of curiosity, how did you find out about this feature (forcing the fan at 80C)? Also, is this specific to HP or do other vendors also support this? Finally, is 80C safe for the CPU (Intel or AMD?)? I read that Opteron chips could be damaged if their temperature reaches

Thanks for your reply Rafael. However, I was looking for a generic solution. I don't have an nx6325 but was thinking of purchasing a laptop and was afraid that ACPI could damage / overheat by CPUs. I think the link you provided is specific to the nx6325 unless I'm mistaken. Is there any generic
