Dell T3500 Blinking Amber 1-3 (4x) issue

This question is answered

I have a problem with my Dell Precision T3500, the issue is that whenever I try to start the computer the power button it blinks amber 4 times and gives the number code 1 and 3 however it does turn on after a while. I assumed that it was something to do with the motherboard hwoever I am not sure since there isn't many problems like this on the internet where I could find a solution. I looked in the manual and the closest thing I could find was that it was a PSU or PSU cable problem. If anyone has a solution or answer for this I would be very grateful. The T3500 currently has a Nvidia GTX 260 installed with 4GB of ram. In addition if it is a PSU problem could you please list what PSU are compatible with the T3500 such as a T5500 PSU or a T7400. Thank you for your support.

  • I hope your machine is still under warranty :)  I've had this happen to 5 of my T3500s.  The fix is a new power supply.  Each time they've sent out the power supply, they've also sent out a new motherboard.  I think there's obviously a big problem with the power supplies in these T3500s, as each one from our initial purchase has had the same issue (we have a bunch of newer ones that haven't shown the problem, at least not yet).

    Each time it happens I request that the tech person try to make this a known issue (and perhaps trigger some kind of extended warranty/recall), but so far no progress there....

    Leaving it unplugged for a bit seems to fix it temporarily, but then we're scared to turn the machines back off.

  • Hi Brandon980,

    Lights 1 and 3 indicate a RAM problem. Try reseating the RAM. If that doesn't help, try removing one module at a time, making sure the remaining modules are used in the correct slots.

  • Thank your for your response but yes I have tryed reseating the ram, removing them 1 by 1 and also placing them 1 by 1.

  • When you replaced them, you're putting them back in starting with slot 1? You tried each individually?

  • Yes I have and it still does not work.

  • You said it starts eventually. Have you tried running the Dell diagnostics or memtest?

  • Not at the momment, I'll try the diagnostics tests, I'll get back to you with the results, Thanks for your responses and help so far.

  • I have just condcuted the Dell Diagnostics tests and there were no problems to report from the memory.

  • I'm still having issues with this 1-3 amber blinking light, Dell diagnostics reads nothing does anyone have any ideas about what is causing it?

  • Ok, time to get back to basic troubleshooting:

    1. Try resetting the BIOS to its default values (but make sure you go into the BIOS and write down the current settings)

    2. Remove all peripherals and unnecessary add-on cards.

  • The tech support person I just talked to gave me this part number as a "known good" replacement part (ie. no repeat problems) for this issue: 6W6M1 (it's a 525W power supply).  They're creating a dispatch for me right now...

  • Ok, let me know how it works out.

    I've seen this one other time for a different model. It was caused by a high-power USB device. When the device was removed, the system booted fine.

  • Since this morning I am facing the same problem with a T3500, it has a NVS295 videocard.

    The powersupply makes a "trrrkk" sound when it starts then the lights 1 and 3 blink 4 times and the machine shuts down. The only usb devices ever attached to this machine are a mouse and keyboard.

    Regards.

  • Just placed a call to Technical support, they are going to replace the power supply,.

  • Ok thank you everyone for the feedback! I am taking a leap of faith and hoping that it is the power supply that is causing this. One more question, Can I fit in any power supply into the T3500 or do I need to use the specific model (6W6M1)?
