Exclamation LED Light In Front of The MCS 7800

What does the Exclamation mark in front of the MCS 7800 server indicates when it is light up?

Hi Shah,
Could you share the server model you are using and perhaps a photo showing where you are seeing this led?

No LED light on front and black screen when trying to start up

Not sure why started my Mac just like everyday and I noticed it had frozen on start up screen was shaky but froze none the less. I tried to restart with the button on the front and nothing but the hard drive kicking in and the light on the button won't stay on like when it is up and running but will flash if you hold it and try restarting. Tried hooking up other monitor and the other monitor won't display so I don't think it is the monitor and like I said I can hear the hard drive and computer come on I just have a black screen and no lighted button on the front. Anybody have any suggestions. My iMac G3 is a 600mhz graphite running 10.4 and classic 9.2 but very rarely do I use the classic on that one as I have another just like it and they were networked together this one is fine. Help!!
iMac G3 600mhz Graphite Mac OS X (10.4.3) also runs classic 9.2

Thanks but that wasn't it. I replaced the battery and reset the PMU, still no luck. I've tried hooking up an external monitor still nothing, in doing all of this the person helping and I noticed that when you push the button on front to power up it doesn't light but I'm also not getting a start up chime, only the click of the hard drive then in pushing the button to power it off the light will blink and I think it is shutting down. Any other suggestions.
Thanks

Front 'notification' LED light not working...

anyone else having this problem? since the 2.2 update my blue LED lights on front of the phone stopped working (it lights up when u have a call) i liked having the visual notification when a call was coming in....i get the blinking green light...but not blue or red (charged phone)....anyone?

i tried a starting the phone on safe mode (to see if it was an app that was causing the problem), then factory reset and pulled the battery,. ETC, ETC (I HATE THE FACTORY RESET SOLUTION, ITS ANNOYING!!) ..
FURTHERMORE, recieved a replacement unit (shutter problems) it was preloaded with 2.1...everything worked fine...i proceeded to update to 2.2, the light went out. I spoke with a tech support guy from verizon...he told me it is a know problem and that not everyone is expericing this. similar to what people are experiencing with their mp3s...some have the problems others dont. im glad that this is the only issue so far...but ido want all the bells and whistles on my phone...and i want them to work!! not asking for much...i want what i paid for...little blue light and all...
PS-i like my phone.

How do i re-enable the mouse pad on my Probook ? the little LED light is on and I want it off

I just received my ProBook and I prefer to use the mouse pad... not the button ... but somehow I have engaged the mechanism that turns the pad off and the button on ( the little LED light is on in the upper left corner of the pad)
HOW DO I TURN IT OFF??

Hi:
There should be user guides on your notebook's support page that will tell you how to do that.
Enter your model number in the Search Products box, and select manuals from the menu.

Blinking LED lights (possible processor issue)

I tried to turn my laptop on today but I was greeted with a blank screen and 2 blinking LED lights. According to the code thing they have here it might be indicating I have a processor issue, is there any way I can fix this or am I screwed? I've gone through google and this seems to be a bit of an issue with certain HP laptops.
I'm running an HP pavilion dv4-2145dx with windows 7. My warranty is also gone.

Hi,
I think your machine has a serious mainboard malfunction. The solderings can be ok, but have you a microscope to check it like a high-grade technician or engineer? The other point is: It can be a malfunctioning resistor or capacitor or whatever, I personally think it must be something like this since the described error points on something of the power subsystem.
You can also try another thing: If you have your keyboard removed and could look under it on the mainboard, then you can try to disconnect a flat cable which must be located on the lower section before the handrest comes. Its not a thin rather a tall flatcable which should be for the panel in front of your machine (which is for the multimedia keys and so on) and disconnect it. Check whats happening, if nothing then you have def. a malfunctioning mainboard, if the machine starts then the front panel pcb is defective and must be replaced.

Satellite P10-554 turns off, cant start again, but led lights still burning

my P10-554 shuts down after few minutes. after that, i cannot start it again, but the led lights are still burning. when i wait a few minutes or hours, then i can reboot my notebook again, but he runs for about one or two minutes and then shuts himself down again...
i thought of a problem with the fan or something like that, but why are the led lights still burning after the shutdown ? what can i do ?

Usually if the AC adaptor is connected to the PC some LED are on. For example the battery LED lights green when its fully charged.
However, its not usual that the notebook shuts down after several minutes of running and for me it sound definitely like a hardware fault.
The problem is that a common user like me and you is mostly not able to fix or locate the malfunction. You need definitely a help from a technician with much more experience.
The ASP guys could run the diagnostic tests and are able to find out whats wrong on the board.

Led In front of the Apple T V don't light up

Led in front of the Apple TV don't light up

Hi Shah,

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.

Can the HOME BUTTON(the circular button under the screen) or any other button on the front of the phone flash an LED light on notifications

pls reply and if it is 'no' then pls advice the apple company to do this in the next iPhone.

Please don't post the same question multiple times. Your question was answered here: Can the back button of an iPhone 5s flash an LED light on any notification
Not on the front, only the LED flash.

Please add indicator LED light for the HDD and sleep back, add some system hotkey

After Lenovo have announced the new T440 T540，we were shocked by the graphic card: GT720m (game card) and no indicator LED for HDD. At last we need a NVS graphic card to do some grophic related work or mobile business.
So we waited for the new w540, after coming to public we were shocked again there is :
- no indicator LED for HDD, sleep, wift and bluetooth,
- no hotkey to disable touchpad
- no hotkey to sleep
- no turn on/off screen hotkey
- no hot plug for cdrom or second HDD
these are miserable and somehow funny, maybe no indicator for apple is ok as most new macbooks are all SSD
rather than mechanical hard disk.
maybe no led for sleep for apple is ok as Mac OS goes to sleep very quick and they use SSD. But for thinkpads we close the lid and wait for the moon LED light to take thinkpad freely, also for the sake of hard disk rotation. Now we need to look at the power button which is impossible when the lid is closed.
no hotkey for sleep ? some friends said " Fn+4 acts as a suspend shortcut (I think it was added in BIOS 2.05)" , we hope it is ok.
no notkey to off display? no hotkey to disable touchpad? It is really unconvenient
So is there update for these minus? Hotkey may update by the BIOS and driver. Will lenovo do so? After testing well, it will be back really easy to use.
And is there any Modle B for w540 to add LED back ? Missing indicator LED for HDD is nightmare for troubleshooting. Miss sleep indicator in front of Thinkpad(A-Side) is miserable for bringing sleeping w540.
Miss wifi and bluetooth is also unconvenient..... And it is not a very hard work.
Also it is said there is no driver update for fingerprinter reader from AuthenTec, because AuthenTec is bought by Apple?
For thoso who do is really smart but also keep the good previous features,
PLEASE

Today on shutting down the W540, I get the Windows blue shut down screen with the comment:
"Operations are in progress, pleases wait. The machine will be turned off automatically after the operations are complete."
OK, so I waited 20+ minutes.... Mouse logo spinning, but no idea what i/o's are going on. Fast disk access? Slow disk access, intermittent disk access? Or is it locked? CtrlAltDel has no action. Mouse cursor does move.
So did a cold boot/restart (still not knowing what was happening in the Black Box). Must have locked up restarting, as I waited 10+ minutes with NO IDEA what was going on, a REAL "black box".
Cold booted again, and tried a Safe Mode. Worked!, and did a check disk - said not errors????. All OK now.... but WHERE IS THE HD LIGHT!!!!!!!
Now I just cheked, the Dell, ASUS, TOSHIBA, SONY workstations have them..... We need to review this carefully at the R&D level, AND NOT LISTEN TO MARKETING! T'was, my fault for deciding on the W540, I never checked that specification, and just ASSumed all the indicators lights would be there! Now I'm stuck with a $2,500 toy - never feeling secure in the work being done. I need rwo more workstartion, but it will be a nuissance to be on two types of workstations.
When I run my Stat package, it takes sometime 1+hr of analysis, I have no idea if the program is waiting, paused, or locked.... no HD activity light, no heartbeat no idea if I need to reboot, or wait. Maybe it's an act ot terrorism to waste US worker's time ???? <g>

My iPhone 5c rear camera won't work and the led light doesn't work either

At first just snapchat wouldn't work and then I tried my actual camera and neither camera worked. I turned it off and on again and the front facing camera works but the rear facing one doesn't. Snapchat wont use either one. Then I pulled up my settings bar thingy and the led light button is all greyed out. I rebooted my phone and it did nothing. Im not sure what to do, help please!

Set it back to factory settings without using any backup data. If the camera does not work after that, you'll have to get the phone serviced.
Use iTunes to restore your iOS device to factory settings - Apple Support
iPhone - Contact Support - Apple Support
If the camera works after that, use the latest backup to restore your data on the phone again. If the problem comes back, your backup contained damaged data, causing this problem and you'll have to start allover again, but without the backup data.

Front LED Light Flash Once Every 3 Seconds

As what I read from the previous post, the front LED light flash once every 3 seconds meant that rams were not installed. However, I can turn on the G5 (Tower) couple days ago. After I came back from vacation, it did not allow me to turn it on. In addition, I have already tried to reseat the ram, and it did not work. Any suggestion to fix this problem?

Hi Teddy, and a warm welcome to the forums!
After I came back from vacation, it did not allow me to turn it on.
If it was unplugged from the AC that could drain the PRAM Battery, 4 years is close to their lifespan...
See which one your G5 has...

Since I installed Lion on my macbook the LED light does not pulse when I close the screen - the sleep function does not work.

Since I installed Lion on my macbook the LED light does not pulse when I close the screen - the sleep function does not work neither when chosen after pressing the button nor chosen in the apple menu..

I have had the same problem but on another forum it was suggested that disabling internet sharing would solve this. This fix seems to work on my machine - why it works I do not understand
