My laptop's got a mysterious extra button on it that doesn't cause any keyboard messages -- I've verified this with a low-level keyboard hook. It appears that it's an "ACPI Fixed Feature Button". Any ideas how I'd go about responding when it's pressed? I found some discussion of how it works in kernel mode. Does this information percola...
Is there a Windows standard way to do things such as "start fan", "decrease speed" or the like, from C/C++? I have a suspicion it might be ACPI, but I am a frail mortal and cannot read that kind of documentation. Edit: e.g. Windows 7 lets you select in your power plan options such as "passive cooling" (only when things get hot?) vs. "a...
I have an ssh connection to a linux machine which is hibernated after some non-activity time. I want to make it resume, how do I do that? (writing to /dev/mouse to simulate mouse movement didn't do the trick) ...
On most newer computers you can shutdown the hard way by pressing the power button for a couple of seconds. But I want to prevent this completely. You're able to prevent some soft events like the sleep, suspend, hibernate and "Press power button" events in Windows control panel; you can also use some Win32 and WDI programming to catch a...
In my Fedora Core Linux (kernel 2.6.16.11), I've been trying to test the auto-shutdown mechanism associated with the CPU temperature. It does not automatically shutdown properly. If my current processor temperature is 50 C and I set my ACPI configuration to shutdown at 55 C by executing the following commands at the prompt: echo -n "5...
Firstly, please don't move to serverfault. It is indeed a programming question :-) We are developing occasionally connected applications. These applications reside on laptop and handhelds. In my case, the application runs on a small servlet container (like jetty). The requirement is that if the system is idle, the application should su...
Hi, is there any simple way to disable processing ACPI power button events (Shutdown) temporarily using the Windows API in Visual C++, so the user isn't able to shut down the computer using the power button? ...
What's the best way to programmatically cause a Windows XP (or above) machine to wake up at a specific time. (Ideally a lot like how Media Center can start up automatically to record a particular TV program) I've got a Windows service (written in C#) and I'd like this service to be able to cause the machine it is hosted on to start up a...
I am writing device software for a PC and for that, I want the PC to be usable as a device. When power is supplied, it should switch on without requiring to press the power button. There are power options in BIOS settings but it starts the PC only when its uncleanly shutdown. The other concern I have is how would unclean shutdown affect ...
What I wanted to do is take a log on battery percentage. I know the equivalent in linux is sysctl(hw.acpi.battery.life). However when I went through the man of sysctl in mac os x I did not find the equivalent code to find it. Can some one point out how to do this using objective c. I can call sysctlbyname but that doesn't have this as in...
I have MS-DOS 6.22 running on a Pentium based computer (motherboard supports ACPI), and would like to know if there was an assembly language routine I could use to shut down the computer, or is it a little harder than that (i.e. motherboard specific)? Basically, I want to create a small program to shut down the computer from the command...
I'd like to communicate with an Embedded Controller device in a Notebook through I/O ports 62/66. When running on XP, the communication might collide with "Microsoft ACPI-Compliant Embedded Controller" driver which does the same thing. Therefore, I’d like to know whether (and how) I can communicate with I/O ports 62/66 using this driver....
I've a netbook that is running the fan a bit to early for my liking. I've found a Windows-only solution to reducing the fan noise but I'm using Ubuntu on this computer. In the Windows solution the guy is using a program called Notebook Hardware Control (NHC) which, from what I can make out, is reading and setting ACPI values. (http://hp...
Hi, I want to use a PyQt application to display an image when some acpi event is triggered under linux. I already setting up the configuration for the event and the python scrip is executed when the event is triggered, but when program reach the creation of the QApplication app = QApplication(sys.argv) it stops without error. I tri...
Is it possible to change the power-saving behaviour of a laptop computer on lid close from hibernate/standby/shutdown to Do Nothing from the .NET Framework? Edit: it would appear that by setting the value to Standby and blocking the standby from my application, the lid close event can be detected, which is what I'm really after. I foun...
Is there any Win32 API for waking up a system that has been shut down, at a specific time? I have seen a program named Autopower On which is able to power the system on at a specified time. ...
