Re: setting sensor limits fails
Dne, 01. 03. 2010 23:55:43 je s. keeling napisal(a): I don't think this should be a threat to your laptop, the sensors only read temperature (and other data) they don't interfere with the working of the CPU, hard drive or other components. I think you have no reasons to worry. They sure help here, otherwise the fan makes it sound like my Sun U30. If failing to set sensor limits is what I think it is, then it's no joke. You should check whether this means that your thermal trip points are messed up (or absent altogether); if they are, your laptop may eventually overheat and die. (However, your fan being so loud is actually a good sign.) The *passive* trip point is particularly crucial in this context. I jotted down some indications about trip points and such on the website you'll find in my signature (once there, look for the heading Laptops In Heat). -- Regards, Klistvud Certifiable Loonix User #481801 http://bufferoverflow.tiddlyspot.com -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

I once worked on an OS which we ran on PC hardware for development purposes, and the CPU would regularly 'disappear' off somewhere for a millisecond or more, making it impossible for a modern PC to even keep a bog standard 115kbit/sec serial port UART from underflowing. :-( -- Tixy -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

If you send me your laptop, I'll be glad to document it for you ;) Seriously, I've messed around with trip points a bit, but never went as far as to let my laptop actually take fire (for obvious reasons). There *might* be an upper hardware critical limit that you aren't allowed to override in software, I don't know. It probably depends on your particular hardware and the vendors particular ACPI implementation. What I do know is you *are* allowed to play around with the thermal module trip points, at least to a certain extent.

I'm not sure if an IBM ThinkPad 600 qualifies as a modern laptop, since it was originally introduced in 1998; but I run Lenny on one of those. In fact, I created a web page devoted to running Lenny on it: http://www.wowway.com/~zlinuxman/tp600.htm. If I recall correctly, the lmsensors module recognizes the particular sensor hardware on this laptop as unsupported and refuses to load! Yet I have had no thermal issues with it. Of course, I haven't deliberately stressed it either, such as wrapping it in a blanket. But I have used it extensively, with no problems. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org
