Memory Dimm1 Red LED

hi, i have a mac pro quad 2009, today i found out that the RED LED lights on dimm slot 1 on the processor tray. and sys. profiler shows that the slot is not populated as 3 x 1GB of the ram is apple shipped stock ram. and i tried to swap the ram at the 1st slot to one another it still remain the same problem. What else i can do other than send to Apple service center?

There is another post on these forums about a red LED. The answer was that it indicated an improperly seated module. A vacant slot should not give such a warning (proviso). As delivered my device had several unpopulated slots. The problem you have may be that slot 1 specifically has no RAM. I suggest you buy another 1GB of RAM and install a total of four modules. put them in slots A1 and A2, and in B1 and B2.
As long as all the modules are of the same technical specification and that is the correct spec for your machine, then they should work.
Best advice is to use two pairs of same make but different makers will work provided they are same spec etc. If you have different makes put same makes together in any pair.
The other thing to be sure of is the seating per se. That seems to be a slot A1(?) issue in your case so you could test it by switching known good modules between the slots to test the slots. Remember to get the thing to work you should have a functioning configuration of modules.

4 Red Led Lights - Please help

the other day I left my computer on for a few hours and when I came home and moved the mouse it wouldn't come out of standby. To get it to shut off, I had to hold the power button down. Now when I start it, the fans start spinning, the DVD drive spins for a second and a few times the orange light on the monitor turned green. But after about 10 seconds, it shuts down.
I have the 4 red lights on the LED, so I swapped in a new PS - Enermax 550W with 36A on the 12v. Still same thing. So I'm guessing either the CPU or the board. I built this about 6 months ago. It's not overclocked and it was idle during the time I left it. Any suggestions?

Yes and no. I know that is confussing. However go to this first as you may have had a problem right along and did not know it nor would you without testing. Memtest86 is a great way to test memory. The no part is that it could be something else. But hey you have to start somewhere.
As for the timings in RAM you need to go to Corsairs page and check the exact model on their charts. Also be sure to read any side notes as they may have specific timings for your A64 versus other CPU's. It can be different as the memory controller is on the CPU in our case instead of on the MB.
Corsair also has tech support that can walk you through memory timings if you don't follow them at all.
You can also have some other thing in the system that went bad even as simple as a HDD cable that came loose. To troubleshoot sometimes the easiest way to find out is to unplug anything that is not needed to boot.
But start with the memory as the 4 Red LED's indicate.

K8N NEO Platinum 4 Red LED at Startup

I installed a new MSI K8N Neo Platinum mainboard in my computer in December 2005, and my computer has been a pain ever since. My problem is 85% of the time when I turn the power on it just won't boot up, I get 4 Red LED lights. If I shut it off and on half a dozen to 20 times. During one of those times it will bootup normal and work great. Shutdowns are normal.
My Family hates this and won't use it. This computer has been nicknamed the MSI Little Witch. I have had it down to barebones out of case with just graphic card, 1 memory stick, IDE harddrive, keyboard and mouse, it will do same thing. I've unplugged and replugged everything countless times. It still does it. I have tried Maxtor, Samsung, and Western Digital hard drives with fresh install of Windows XP Pro, it still does same thing. I have alternated memory sticks, same thing. It will warm reboot as long as I don't powerdown, but if I shut the power off it will not reboot until it cools down about 20 minutes. Then I can go through the same startup problems as I normally have. I have not done any overclocking.
Anyone have a fix to this fustrating problem?

I have the same problem with my K8N Neo Platinum. Except mine seems to occur after the motherboard has not had power after sometime. For example, it happened every time I moved my computer when I moved into and out of my dorm room. I don't know if its the same "cooling down" time you're talking about, but what usually fixes it for me (at least temporarily) is killing the power to the machine while it is on. Regular soft resets won't work for many tries, but when the computer is on with all 4 red LEDs i'll flip the power switch on the power supply. That usually makes it work fine. Also another thing that seemed to intermittently trigger it is changes to the BIOS. A CMOS reset would not fix that either. I would have to flip the power switch and kill the power. Then after starting it
up again it would be okay. I have also tried multiple combinations of different cpus, memory sticks, and video cards. I also made sure there were no shorts to ground anywhere.
Also after a year of solid operation (with the exception of this problem) I started to get Machine Check Exception BSODs in XP. I think this was because of a possible bad stick of RAM, because that seemed to cause lockups in the way beginning of the Windows setup (where it is loading files such as Windows Executive, etc). When I removed it and put another stick in, the windows installation would go fine. But, that did not fix the issue with this motherboard.
I've had so many problems with the multiple K8N Neo Platinums I have purchased. This is absolutely ridiculous I'm extremely POed at MSI for the widespread K8N series problems. I am usually very tolerant to companies when they have problems with products because I understand that problems and glitches can easily occur in mass production and design. It is virtually impossible to make a "perfect" product from the start. But the lack of response and concern from MSI about this is ridiculous. MSI did make an excellent motherboard here--if you can get a working one.

Red LED inside Mac Pro...

So I have this issue with constantly having to unplug my Mac Pro from my UPS and hold the power button to reset it so that it boots up with Bluetooth so I can use my mouse. I notice that there is a red LED glowing inside the Mac Pro on a card and it doesn't quit even after I unplug the system to reset it. Is this how I have to keep powering up for the rest of the time I own this 2.8Ghz Quad core? Seems so annoying. Anybody know what I'm talking about? "Do you know of what I speak..."

y'know - I thought my details were under my post, I might be thinking of another forum, but good questions! I am talking about my 2010 2.8Ghz Quad-Core Intel Xeon "Nehalem" Mac Pro, 8GB (4x2GB) 1066MHz DDR3 ECC memory, 1TB SATA HD, ATI Radeon HD 5770, (driving two Dell 23" UltraSharp 1920x1080 displays via miniDisplayPort to DisplayPort).
I am on Snow Leopard OSX 10.6.8, running FCS2. I have a hardware RAID card running a CalDigit HDElement, and I shoot on XDCAM EX and 5DmkII in terms of video rpoduction except when I also pull in some ProRes files shot on XDCAM HD and DVCPRO HD. At work (my full-time) I am on a 3GHz Dual Quad-Core running Snow Leopard and FCS2, and we use a 16TB SAS RAID also with a hardware card all from DAT Optics. I've been cutting on mac's for almost 20 years or more and very familliar with the side panel, the ram slots, the hardware and the apps. (not to sound experienced, but just so you know where I'm coming from).
I'm still at work, and my Mac Pro is newer than the one I'm cutting on here at Keystone, so I can't tell you yet what the marking is next to the persistant red LED light, but I will later on tonight or tomorrow.
Thanks for any help. -s

It sounds like some of your memory may be failing. If you open System Profiler and select memory, are all of the DIMMs listed as being OK or do some have ECC errors?
Are all of the DIMMs properly seated on the riser cards?
Make a note of which DIMMs are giving you the red lights. If you then move that or those DIMM(s) to another slot or to the other riser card, does the problem follow the DIMM or does it stay with the card?
If so, then those are the problematic DIMMs and should be replaced. Apple will probably replace them if theirs are affected (assuming they're still covered under warranty). OWC, I believe, has a lifetime warranty on their RAM. The "other" RAM you listed....is that specifically designed for the Mac Pro? If not, it will likely overheat and fail...

6970 Lightning in crossfire Red leds

So i got 4 red leds burning in both cards.. and im wondering is it normal or have i plugged em into my psu somehow wrong?
Ty

its normal, its APS feature,
dynamic adjust phases[14 (for gpu) monitored from total 18(remaining are: 3 for memory + 1 for PLL)] depend of load to save power
4 burning reds means that currently VGA is in full load [Phases: 11,12,13,14 light in red and 1-10 light in green]

Cpu or mobo broken? (four red leds and CD ticking on 865PE)

Hi folks, hope you can help me out.
My 2.5 year old system died today while using it. It's an 865PE Neo2 with a 2.8GHz P4 and 2x512MB RAM.
It doesn't POST and the D-bracket is showing four (all) red LEDs. What is also interesting is that there is some kind of activity on the CD/DVD drive (is ticking continuosly) and the keyboard Num Lock / Caps Lock / Scroll Lock LEDs blink at irregular intervals (all at the same time).
Does this indicate if it is the CPU or motherboard that is broken?
[I have disconnected all accessories + reseated the two power connectors, the memory sticks and CPU but no improvement.]
Cheers
Mike

I bought the computer "ready-made" by a computer manufacturer so I haven't been involved in the choice of PSU, but I expect the specs to be sufficient as they built lots of systems of this model. The computer is a "low noise" model (PSU labelled "w/noise killer") so this has probably affected their choice.
Anyway, the specs are:
DC out: 350W
3.3V+5V: 220W max
3.3V: 28A
5V: 30A
-5V: 0.3A
5V SB: 2A
12V: 16A
-12V: 0.8A
I thought my measured voltages looked fine, but was there something that caught your attention and indicated problems with the PSU? (Or maybe rather the failure statistics you mentioned earlier?)
Thanks
Mike

Wont turn on /blinking red led

Hi all, have my xperia z3 for about two weeks, not rooted, not unlocked, without any modifications. Yesterday before sleep it was with more than a half of akku, today as im woke up and got it in my hands it was off, im plugged charging cable, was thinking maybe the battery was drained, but nothing happens still, its just blinking red (led).
Was trying to hold power + volume up, nothing.
Reset key near sim dont works for me either - i'm just notice 3x vibrations and thats it, its just repeat vibrate 3x times again and again but nothing happens, no boot.
Solved!
Go to Solution.

You may need to perform a software repair using PC companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% battery.
Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).
Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).
All we have to decide is what to do with the time that is given to us - J.R.R. Tolkien

P7N SLI Platinum - no post - red led on board

Hi
I'm curious if you know about what that little red led light near the battery means.
I have the motherboard for 2 y now, no problems (no oc, 7 fans on the case), but tonight I got a BSOD playing l4d , reset and then it won't boot.
The fans are spinning, all of them, psu included, no Hdd activity, the monitor is black, no signal at all. And that little red led near the battery that I don't remember seeing lit till now, and i see there's another one, blue that's also lit when power on.
Pressed the little reset bios button on the back ,changed the vga and rams with working ones from my other system....same thing.
config: Antec ninehundred-well ventilated , Seasonic 650W psu , q6600 (45C medium load) , Mushkin rams , 9600gt
Is it dead ?

And that little red led near the battery
That was there before. It indicates that a swtiched-on PSU is connected.

Is it dead ?
At this point it is impossible to tell.
Please test with one memory module only, unplug the PSU from A/C power and >>Clear CMOS<<.

K8N Neo-FSR 4 Red LEDS

I put together an amd64 system:
K8N Neo-FSR
AMD Athlon 64 3000+
1024mb corsair valueselect (2x512)
When I power on, I get 4 red leds on the dbracket, which is supposedly a damaged or incorrectly installed cpu. I am 99% sure that both of the cpus that i tried were good, but I am 100% sure that one of them was. I also tried reseating them a few times. Is there anything else 4 red leds means?
Also, the computer turns on with the powers supply switch and the power/reset switches don't work at all even though they are plugged in to the correct places. Anyone got any ideas?

I had the exact same problem. Thought it was the CPU, so returned it and got a new one, and the error continued. Here's how I got it to stop:
Take EVERYTHING off the mobo. All the PCI/AGP cards and the ram. You can leave your drives hooked up, but unplug the power from them.
Then, try to reboot it. When I did that, it finally got past the 4 LEDs and gave the memory error leds. So I put in the ram, and it gave me the next error. So on and so forth. I kept putting in whatever piece of hardware it was crying about, until it got all the way through, at which point I put in my extra stuff (sound card, tv card). Yes, it's a pain in the ass.
When I was putting them back in, the only thing I did different is I put my tv card in the slot above the orange PCI slot (the one on the bottom that is "enhanced"). I'm wondering if that wasn't the problem to begin with.

Faulty Mac Pro "Red LED" on Processor Tray (not RAM LED)

Hello.
I have a faulty Mac Po and wondering if someone can advise.
There's a red LED constantly switched on on the processor tray (see photos). It is not one of the RAM diagnostic LEDS.
The Mac Pro does not load up. It does initialise the RAM and boot up the Hard Disks.
At the same time the Graphics card fan spins very fast, and no input is detected on the display. I have removed it (in the photos) just in case it overheats.
I have plugged in the graphics card and processor tray on an identical Mac Pro and they both work fine. I have also swapped out the small button-battery fo a new one.
I have also unplugged all cables, reseated the RAM and removed any non-Apple RAM, leaving the shipped RAM in place.
If anyone has any ideas what this might be I'd be grateful for a response.
With thanks in advance

PM8M-V no beep no boot Solid Red LED

I've had the PC I've been using for about 2.5 years, no problems.
Last week a lightning storm killed all the AGP/PCI functionality of my old motherboard. At first, I thought it killed my AGP video card because the internal video to the old motherboard worked fine. This is where I decided to buy an MSI PM8M-V from CompUSA.
Tried installing the board today. I literally just powered down the PC with the OLD Board in it and it all was working fine. The two motherboards seem to be similar in quality and both have internal sound and video.
With the new motherboard hooked up when I press Power the CPU fan comes on, and the LEDS on the front of the tower come on. The RED LED [Which I believe is the HDD LED, will have to double check] comes on and stays lit. After about 20 seconds or so the system powers down. I get no beeps or anything. I doubt any of the components are bad because they were all just working 1 hour ago.
Does this point to a specific problem? I don't think the CPU is overheated as I have thermal paste the Heatsink fits snug.
Suggestions?

Ok, an update.
I have an Antec PSU 300W that appears to be working well.
At the moment I have 1gig of unknown brand DDR memory
I have a P4 Prescott 3.0GHz [I don't recall any of the other details as this PC is several years old]
All hardware pulled from a perfectly working system with the exception of an AGP slot on the old motherboard.
The old motherboard has nearly the exact same features and appears to be of very comparable quality.
I hooked the old motherboard up with the processor, memory, and same PSU and it booted to the BIOS just fine.
This new MSI motherboard WILL NOT boot to the BIOS with the exact same equipment installed. I have double and triple checked.
Is there anything else I should do before contacting CompUSA for a return. I've seen some recommendations about jumping pins to clear the CMOS or something.

After falling red led for 3 seconds then dead

Hi,
after falling on the floor my blackberry 8800 will not start anymore..
When I insert battery or charger cable the red led lights up for 3 seconds then turns back off but the device is dead...it the anything I can do?
Iv found other topic's talking about red flashing light and firmware reload, is this the same thing?
Thanks for any help!

Hey mau_mau,
You can try to reload your operating system but most likely all your data will be lost.
You can try to see if the device will connect to the BlackBerry Desktop Manager to back up data, but there is no guarantee it will be able to do so.
You can consult article KB11320 for instructions on how to do the load.
If you need further technical assistance, you can contact your wireless service provider.
Thanks and have a great day!

WRE54G keeps getting Red LED

I'm having some problems with my Linksys WRE54G connecting to my WPA enabled, Linksys WRT400N. I've setup the WRE54G successfully (able to access to web setup page via 192.168.1.240 and configured it manually, I moved it to the part of house that I wanted to and was able to successfully connect with the Wireless G laptop with good connect rates (ranging between 80-130Mbps). The WRE54G had two good blue solid signals. However, this morning I noticed that it had a Red LED and now I am unable to connect via the web page to check the configuration. I reset the WRT400N and I'm still getting the Red LED. I am using Channel 1 which I've heard shouldn't be used although frankly I didnt see a way on the WRT400N to force to broadcast on a specifc channel if you're using a Mixed Network mode.
Do I need to setup a static IP address on the router for this device (I only have 6 devices connected to the network so I didnt think this would be a problem for a .240 address).
Any help troubleshooting would be appreciated.

Make sure that you have assigned the static gateway on the Range Expander.Try to change the channel on the router and range expander.On the router,change the Radio band for 2.4GHz to Standard,Change the Security to WEP.Now,Power cycle the router and range expander.Now,check.
