Front Panel Power Leds

Hello Community!
It has been a couple of weeks now that I have been experiencing the following issue:
The on/off power button does not light anymore, neither in blue (operating) nor in orange (stand-by). My PC is working properly, no further issue.
What could the cause be and how can I resolve this problem?
Thanks for your help.
System: HP Pavilion p6747CH-M/i7 2600/W8.1/8gb/1TB/ASUS HDMI 2GB

Hello lusstik,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that you are having issues with the LED light indicating the unit is powered on or in standby mode is no longer working. I suspect the Power LED indicator is no longer working and needs to be replaced. You can order the Power LED holder assembly (Part Number - 499769-ZH1) from the HP Parts Store and replace it. If you do not feel comfortable doing this yourself you can contact HP Technical Support for repair options as well.

X-Fi Platinum Front panel Power QUESTION

? Hi All, I have X-Fi Platinum. Does the front panel require A power connection. If so what kind of connector do I need? Run from the card to the front panel? Cant find manual on line!? THANKS IN ADVANCE

This requires a four pin floppy power connector. If your case does not have one you can find a molex to floppy adapter very simply on online retailers.

Front panel led connectors cables problem

Anyone knows how to connect the cables for the front panel power and hdd switches and leds to the jumpers on the board? The cables have wordings printed on one side of the cables (power led.. hdd led.. etc).. i'm not sure which side should be facing up on the board ... is it the side with the wordings facing up or the opposite side without the printed wordings ? i'm worried that i may end up short circuiting the board if i connec them the wrong way round ... thanks

The are just switches, so there is no polarity to worry about. the led's are polarity sensitive, so If they don't work, just reverse the connection; no damage will occur.

Front panel and audio header pinouts required for Lenovo 3000 J200p 9689

I have re-cased my computer as I love the PC but the Lenovo case is but ugly! The problem is I gave the Levono case to my mate before checking the pinouts. I assumed it would be in the tech manual but it's not. I have got the power switch connected so all I need are the leds and audio.
Would be greatfull if someone could take the time to do this for me.
Many Thanks.

Hi,
I have this same issue. Can we get a motherboard manual for 8705-G6U? I was able to figure out Front Panel power switch, PWR LED and HDD LED but audio is still a problem.
Thanks in advance.

That has nothing to do with front panel connections nor HDD LED. There is no HDD LED on the MB as far as I know, at least there is not after looking through the manual. Does the front panel HDD LED light up?

LEDs on front panel

Employed my Vista Pavilion for several years without incident until last night when I noticed the top "on/off" button which usually glows a light blue was unlit.   I originally assumed a power glitch, so I just restarted the machine to note the following:
    Fans come on and the power supply seems OK, but the system did not boot.   The screen was just black with no characters or image/background. In fact, the screen's power saving mode soon engaged indicating the video card was not sending a signal. Never get to the BIOS screens.
     Now here is what I think may be significant: the green LED and blue LED in the front console were on continuously.
Sometimes, hardware manufacturers provide diagnostic information by way of the lights (e.g., washing machines).   In other words, turning on LEDs can provide state information. Is this true with HP hardware?
Some more clues which tell you what is not the problem. I happened to have a new power supply handy, so I traded it out with the same results.   In normal operation, the green LED indicates disk activity, so I just removed the disk entirely to see if the green light would go out.   Nope, still on steady.   The blue LED typically implies the WiFi operation but I rather doubt at this pre-boot state the WiFi would be working.
I traced the power button line (two grey wires) to a half-sized board in the rear. No breaks in the wire or bad connections.
Any ideas?

Don't understand this reference to a half-height board.
The Front Panel Header (9-pin, 2x5) on the motherboard is where those front panel LEDs and buttons are terminated.
EXAMINE Pictorial in the Internet link to motherboard (above).
HOWEVER, some HP Desktop models have a front LED to show the user of LAN or Wi-Fi connections.
That wire would connect to the network card or motherboard via a different connector.
Some Media PCs of this era (2008) had Infared connections (option) for remote control of TV tuner option card.
LEDs do not last forever (have a long, but finite life) and can fail due to DC over-voltage or surge conditions (environmental, component failure).
In addition, this Desktop PC is now 7 years old .... a long-life for any desktop.
IF the motherboard has failed (component failure, such as capacitors), then replacement may be best advice.

Can I Bind a Front Panel LED to a specific element in an array of booleans?

In LabVIEW 2010 I have a string of LEDs. I have and array of boolean values that contain the values that the LEDs should indicate.
What is the best way to connect the LEDs to elements in the array of booleans?
Can I Bind a Front Panel LED to a specific element in an array of booleans?
How is this done?
Can anyone show sample code?
Solved!
Go to Solution.

Imagine that you have an I/O card that provides 128, 256 or 1024 digital inputs and the requirement is to have an LED on the front panel to represent the state of each digital input. This frequently occurs.
Wiring that many digital inputs individually is a royal pain and then some !
It would make sense to have one shared variable as an array of Booleans that represents the status of all inputs and then use data binding instead of wiring each individually. The individually wiring would violate all recommendations on diagram size and fan out.
Frequently scanned For loops to update all of the LEDS would take alot of CPU time.
Wouldn't it be MUCH better if PSP could be used to update the LEDs whenever the data changed (as it is supposed to do) ?
In my case I have a LabVIEW Yaskawa servo driver that provides me information about 16 servo drives that may be connected. I have LEDs on the front panel to represent some of that status for each individual drive. But Yaskawa provides the information on the drives as an array of clusters of information for each drive, which I perform some business logic on and turn into shared array of Booleans to feed the LEDs (and some banks of switches as well).
Unfortunately LabVIEW does not seem to have any way to bind the LEDs (and Switches) to individual elements in the shared array of Booleans. It is just not that smart. Even with only several banks of 16 LEDs and Switches, wiring them individually using Decimate Array of Index Array functions is a royal pain and makes the block diagrams very large. It would be much worse and almost unreasonable to do if the size of the information was much larger.

How to set front panel size to be same as one led?

Hello All,
LV2010
In documentation reads that minimum front panel size is one pixel. I need to create front panel which have same size as one led (see attachment). I'm not able to make front enough small just by dragging window borders. I also tried to change front panel size from File->Vi properties ->Window size but that didn't helped. How I can set front panel to smaller size?

Small_front_panel.vi ‏6 KB

I think I got it
In the window apperance option I removed everything except "Allow user to resize window" And the Run options. Then I ran the VI (continuosly since there is no loop) and resized it. After I stopped it, I then removed "Allow user to resize window" from the window apperance options.
P.S! If you try to resize my Vi now, it will pop back out for some reason.

Can I use a colour palette control to set the colour of an LED on front panel?

Hi,
I want to allow the user of my LabView program to be able to set the colour of an enlarged LED on the front panel using a colour palette control also on the front panel. Is this possible or can the LED only be the colour it is set to in its properties dialogue box?
Thanks,
Dave.

The question is of course: "Does it really need to be a boolean LED that has a True/False and all the boolean logic???
If you just want an LED lookalike where the color can be easily controlled programmatically I would recommend a color box indicator instead. You can even customized it to look like an LED! The attached example (LabVIEW 7.1) shows both methods, but the color box option is programmatically much less messy (no bundling, no array building, no property nodes!).
(To make the LED color box indicator, I customized a plain color box and simply imported the graphic elements from the regular LED indicator.)

How do you control LED lights on the front panel to identify the number of steps a stepper motor has taken?

I am controlling a stepper motor that is coupled with a valve with four outlets (using an Arduino). I've got a general understanding of how to control the motor, but I want LED lights on the front panel to light up that indicate which outlet the valve is currently at after the steps are taken. The method I'm thinking about involves a lot of repetitive code. I'm not that experienced with LabVIEW, I'm assuming I need some sort of loop structure but I don't know how to set it up in order to control the sequence of the LEDs. I've attached my current block diagram for a visual aid if needed.

I was thinking about using the Stepper To Go and Stepper Write functions four separate times, using the same constants for the steps each time since the distance between each outlet is equivalent. The only difference would be what's connected to the "steps remaining" node, which would be the function that activates one of the four LEDs (if that makes sense). I was thinking that doing it this way would be a little counterintuitive since the only thing that needs to be changed is the LED indicator.

Accessing front panel LEDs in several subVIs

Hi, I'm new to LabVIEW! Ok, what I'm trying to do is create a front panel with 9 LEDs. Then I have a Menu Ring, with three different options. These options determine the order in which the LEDs are lit. So what I was planning on doing was creating three subVIs, one for each of the options...but how can I do that when I only have one boolean for each LED? So basically how can I relate the LEDs on the front panel into the subVIs? I tried using globals - but it seemed like that just passed on the state of the boolean instead of allowing me to actually change the boolean in the subVI. I hope this makes sense...I'm really confused! Thanks for any help!

Initially, you might just hook your ring to a case structure to
determine which frame exe
cutes. You can put the terminals for the
Booleans in the different diagrams and about the only other thing to
keep in mind is that you probably want a delay in the loop.

Satellite A200-1N1: "Satellite" LED on the front panel is not shining

Hi folks!
I notice that my LED with "Satellite" word on the front panel doesn't shine.
Do you have any assumptions about causes?

Hi Maresha,
The front 'logo' LED is enabled or disabled using a BIOS option 'Display Front Logo' which can be set to ON or OFF as you require. Access your BIOS settings (F2 during boot up) and check that this setting is set to 'ON'.

NI DC Power Soft Front Panel Error - 200247

Hello All,
I am having trouble opening the ni DC power soft front panel. The error message I repeatedly am seeing is below:
When I try to run the vi mentioned in the error above, the same error occurs:
How can I go about getting my soft front panel to work? I have been using the DC power API to execute tests over the past week using the example VI's, but am at a point where the soft front panel would be very helpful to my workflow.
I am using the following:
NI PXIe-4139 SMU
NI PXIe-1082 Chassis
NI PXIe-8360 Controller
Windows 7 64bit
Labview 14
MAX 14.5.0f0
DC Power 14.2
I have tried running the soft front panel using clean installs of DC Power 14.1 and 14.2 and see the same error message. I have uninstalled the other modular instrument driver packages on my computer, NI-Fgen and NI-Scope, reinstalled DC Power, and still I see the error message. It could be that I am not uninstalling these software packages 100% correctly (I use the windows add/remove to NI Remove software dialog process....)
I appreciate any help getting this DC Power soft front panel working.
Thank You,
Andrew Goett

Hi Andrew,
Can you possibly give me a MAX technical report for your system? The instructions can be found here. Use Method 1.
Also, can you check which version of niModInst.dll you have on your system? This file can be found here: <Program Files>\IVI Foundation\IVI\Bin\niModInst.dll
Right-click on the file, select Properties, and then click on the Details tab. The information I need is the "Project version" field. See the image below:
In addition to the MAX report, could you send me a ZIP file of the contents of this folder: <Program Files>\National Instruments\Shared\niModInst
I've attached a simple program (NI-ModInst Code.vi) to test if NI-ModInst is failing across the board or if it only is failing to identify NI-DCPower devices. Open the program, select a driver that you have installed on your system, and run the program. The code should tell you the number of devices you have in the system that are associated with that driver, as well as list out the model numbers for those devices. This list will include simulated devices. Test the code with various drivers in your system to see if you get the same error.
Let me know how this works out.

The PWR MGMT LED on the front panel of the sup720 is off. What happen with this?

The PWR MGMT LED on the front panel of the standby sup720 is off (But the active engine is on). We check the switch guide which states "The SYSTEM and PWR MGMT LEDs on a redundant supervisor engine or RSP are synchronized to the active module.". What happen with this? Thanks!

HI @bingxiong.feng,
This is not a cause for concern as Cisco says in the following link:
