Set the max power to zero?
|

From my understanding it will not necessarily turn off the device power.. its more like a “recommendation for the hub. (i.e if a device claims its max usage is 10ma but you use 100ma it might disconnect the device)
I'm willing to test it again (on several computers) if you’ll point me to a working test application..

now i want to get some informations about the local Floppy Driver. the information may content Vendor ID, Product ID ... or some thing else~
can anybody give me some hint?
if C/C++ can do this tell me how, if not give me some explaination.
thanks ~~~

For a floppy drive? There isn't a way to do this. The Device Manager in Windows doesn't care. As far as I know, most of them come back as a Generic Drive on a Standard Controller. About the only ones that would come back with any information are the old 120MB Super Drives.

Hi there, does anyone know in what memory location I can read the CPU tempreture\fan speed. I am guesing it is a memory location, as that would be the most logical...but it could also mean that every motherboard is different. In my case I want to read this information on an IBM Anyplace Kiosk. Google has let me down...Please help!!! Thanks.

There isn't any. This is usually polled from an I/O port in the machines chipset. The location (port#) changes from manufacturer to manufacturer. It's not Google that let you down, it's IBM because they don't publish this kind of information easily.
You're best bet to to crack open the box, get the chipset manufacturer and ID information, then start Googling around for that instead. You might actually come up with a couple utilities that will return the data for you.

I need to do this in software from C#. But after my initial search there seemed no way to do this...this was why I posted in the hardware forum because I thought would have to do it the hardway. HOWEVER it seems I am in luck, the temperature reading is implemented in ACPI and is available as a WMI object, provided the correct drivers are installed. Found a great example on this site:
http://www.cicoria.com/cs1/blogs/cedarlogic/archive/2006/11/29/404.aspx[^]
Works well on my HP laptop, but not on my desktop which has an MSI i975 motherboard which is about 3 years old... Holding thumbs it will work on the kiosk...(have not got one to test this just yet). Now I just have to find a way to get the fan speed.

That's right! So long as the WMI providers are installed AND that they actually provide the data you want. Sadly, most don't! From IBM, don't count it working.

If you can find out what the BIOS for the board is you can use speedfan to get the numbers. There's an option to get user created mappings for most major mobo designs, if IBM used something wierd in the kiosk you might have to figure the locations out the hardway, but otherwise you should be good to go with it.
PS if the board's a few years old you could also try motherboard monitor, but MBM has been abandoned by the developer and doens't support newer boards.

Is the Win32_TemperatureProbe class of any help?

Only if the WMI Providers for the MoBo have been installed. Most of the manufacturers don't bother creating the providers for this stuff. Other stuff, like the motherboard and manufacturer details, yes, but not the fan and temp counters. Pity, 'cause I would like to use them myself.

I was given a machine to work on, but found that the video card (it's a VGA/S-video/DVI card with an AGP connector) was faulty. To get the machine up and running, I simply pulled the original video card out and replaced it with one of my own (it's a VGA card with a PCI connector). That all worked fine. After I got the machine done, I swapped the video cards again, and, no surprise, it did not work. I just wrote it off as a bad video card and told the owner that he simply needed to buy a replacement. He took the old video card with him to ensure an exact match. He tells me later on that the new card does not work. His LCD monitor has both VGA and DVI connectors (as does the video card) so he tried both. I looked at it again, tried both connectors, several cables, all to no avail. Each time, the monitor would simply display, "No data. Check connection." I tried my VGA video card again, and it worked fine. So...
At this point, I don't know if it's the new video card or the AGP slot on the motherboard that is bad, or if I am just doing something completely wrong. Ultimately he could just buy a VGA video card with a PCI connector and be done, but that still does not solve the mystery.
Any ideas?

Check the bios. There might be a manual setting for the video adapter to use as a primary display, and that might have changed to "PCI only" when you removed the AGP card and used a PCI card instead.
Cheers,

Thanks. I'll check the BIOS settings this evening.

As was mentioned, check the bios, especially if there is an onboard video that was disabled. Often the bios does the interchange between the onboard graphics and the AGP slot activating or deactivating one. Similarly there is sometimes a PCI slot near the AGP that is on a swap interface in bios, either-or, not both.
Strictly on the AGP side, you can set a 4X AGP to 8x only via Bios if you put an updated bios into an older motherboard, resulting in a non-functioning AGP slot due to timing irregularities from the BUS.
When you are not sure of an AGP issue, drop the timing back to 1x or 2x if available and test upward. It is possible a voltage flux on the motherboard as changed the timing on the BUS making 8x AGP unusable even on an 8x board, but 4X AGP might still be available because of the wider timing, or 2X.

Most of this is Greek to me, Jeffry. The owner indicated that the computer used to work, but has sat idle for several months, if not longer, because it had Windows Me on it and was thus very slow and sporadic. Rather than fight with it, he just pushed it aside. He asked me if we could resurrect it by installing Windows 2000 on it. I did and it screams now (although it's a bit hard to see!).

which is what I expected. Basically my answer was the longer version of check the bios. There are many possibilities with AGP depending on the bios and configuration. Sitting idle long enough to get an interruption in CMOS backup battery (or a "minor" static shock) would result in a default CMOS setting, factory defaults, whatever those are. That would effectively change the settings from working to possibly not working....
Also a stronger static discharge to the VGA port could A) take out a card B) take out an AGP slot.

an? I wasn't aware of any 2xagp boards in existance. What would the point've been. AFAIK there were no nongfx cards the used the agp bus, and PCIe predated the rebirth of SLI, so there wouldn't've been a need there either.

it was my poor english way of saying that a static discharge any time during the idle of the computer, could have resulted in killing either the original graphics card, or the slot that the graphics card was sitting. I'm just a country hick who does 3D graphics.

I checked the BIOS and it indeed had a setting for selecting PCI or AGP. Even though it was already set to AGP (which is odd since the PCI card is the one that works), I tried toggling it back and forth between the two but still could not get the AGP card to work. There was no setting for speed (e.g., 4x, 8x).
Another anomaly I found was that with the machine working using the PCI card, I could simply insert the AGP card into its slot, power on the machine, and it would immediately start beeping.

You could also try inserting and removing the OLD (might get damaged) AGP card a few times (with the PC switched off, of course). That might help to remove potential oxidation from the contacts. Also, you could try vacuuming the AGP-slot or cleaning it with compressed air.
As for the BIOS:
Does it work if you select "Load Fail-Safe Defaults" (or, depending on the BIOS, a similar menu entry)? The CMOS might have been lost over the time.

Sebastian
