Memory or Read-Only Memory (ROM) failure If competent, take the memory out and try the following - if there are two DIMMS then try each one in each slot to see if there is any change, if just one DIMM the try both slots and also try no RAM installed and it should produce a 2,3 code. Manual at https://dl.dell.com/content/manual36483742-dell-g15-5515-service-manual.pdf?language=en-us and memory at P. 24 Remember to insert and remove at 45 degree angle. Good luck Got warranty?

RAM issue, visually inspect it to see if any chip looks damaged on the sticks If no visible damages, install one at the time and see if anything changes If nothing happens after the test you might need new ram, if even with new ram fails, it’s a Motherboard issue

If your product is in warranty, you can easily reach out to tech support right here. Just click the Get Help Now button at the bottom right corner of the page. The button is marked with a help icon for easy recognition as per the picture below: Now, if you prefer to troubleshoot your system on your own, please note that a pattern of 2 amber lights and 4 white lights indicates a Memory/RAM failure. Follow these steps to resolve the issue: Shutdown Your Device: Ensure your device is powered off completely. Disconnect Power: Unplug the power adapter and remove the battery (if applicable). Re-seat the Memory Modules: Open the access panel to your device's memory modules. Carefully remove and then re-seat each memory module. Ensure they are properly secured in their slots. Check for Loose Connections: Examine other internal connections, ensuring all components are securely in place. Power On: Reconnect the power adapter and battery, then power on your device. Observe if the issue persists. If reseating the memory doesn't fix the issue, try performing a Hard Reset: Turn off your computer. Disconnect the power adapter from your computer. Remove the base cover. Disconnect the battery cable. Press and hold the power button for 20-30 seconds to drain the flea power. Install the battery. Install the base cover. Connect the power adapter to your computer. Turn on your computer. Important: If the pattern of 2 amber and 4 white lights started after a RAM upgrade, it is likely that the RAM is not compatible with the system. Important²: If none of the above steps resolve the issue, it is possible that the motherboard may be faulty and require replacement. We recommend contacting technical support by clicking Get Help Now in the bottom right corner of the page, or reaching out to a trusted technician for further assistance.

My solution was to replace the motherboard. No idea how to reflash the bios if, indeed, that was the problem.

@Rick0167 I'm glad you got it working. Bad batteries have thrown error codes before that are either off-track or erroneous and have nothing to do with anything.

Thanks for the help and replies Found the date/year (Oct 2018) stamped into the chassis. Will pick up a battery in the next day or two and try resetting the CMOS, hopefully its not the motherboard. The only other things I can think of is I did have some problems with this PC when trying to install a M.2 SSD. See https://www.dell.com/community/en/conversations/optiplex-desktops/help-think-i-broke-my-computer/647fa20ef4ccf8a8de7716f8 If memory serves me right there was a little spacer that goes between the M.2 SSD and the motherboard that was missing so I used a small brass nut of the same size to act as a spacer before fastening the SSD to the motherboard. Maybe this could be causing the error code?

G5 5000 desktop - blinking power light - 2 amber / 4 white when turning on.
When I went to turn on my G5 5000 all I got was the blinking power light... some quick searches told me it was a memory error. I only have 1x16gb ram and it is in the second slot from the cpu (the first white tab slot). So I did the only thing I know to do, which is pull the ram and then re-seat it back in the slot. That didn't help at all, as I got the same lights. So I took the ram out again, and I put it in a different computer, and it worked fine. I saw that it showed in the total memory of that computer. So I figure it must be the motherboard. But just for fun, I decided to try the ram in the fourth slot from the cpu (the second white slot), not knowing if this would even work, since all I had ever known was to load memory sticks from near to far from cpu. Well, low and behold, when I powered it on I didn't get any blinking lights... but it went into the Pre-Boot System Performance Check and when finished said there was a critical error (which I knew). However after that I was able to get into Windows, and it has been running fine since. So I guess my initial question is, is it ok to run it in that slot ?
So here's a little bit more to the story (ah!) and trying to determine if I did this to it. As you can see in the attached photo, I have installed the Noctua NH-U9S to help with the well documented underwhelming stock cooler provided. Is there something that I could have done while installing that, that could have shorted out that memory slot ? And does this mean I am stuck with single channel memory forever ? I was just wondering (and haven't tried it yet), does this mean that the first black slot is fried too? And since the second white slot worked, and provided the first black slot works, can I just use the black slots - or does something need to be in the white slots ? Sorry for so many questions, I'm learning on the fly here.
Thanks in advance to any help that can be provided.

Following for this one, Noctua NH-U9S is the next thing im adding.

That's certainly interesting, I wouldn't think simply adding the cooler would have caused a RAM related problem. Did this RAM error occur right after you installed the CPU cooler? Somehow did any kind of dust or debris get in the RAM slot? And I'm also not entirely sure whether or not that first slot will work I guess you will have to try it. I'm not sure if you'll have clearance for it though with that cooler, at least with how it looks in your photo.

For example, the power status indicator blinks amber two times followed by a pause, and then blinks white three times followed by a pause. This 2,3 pattern continues until the system is turned off indicating the Recovery image is not found.

4 white-2 amber is a memory failure. Unplug the system, remove the base cover and disconnect the battery from the system board. Hold the power button for 30 sec. Reconnect the battery, replace the cover and see if the system will then POST and boot. If the same error occurs, the memory is bad. On this model, the memory is not replaceable - you must replace the system board. Hopefully, the system is under warranty - if it is, contact Dell. If it is out of warranty, you're facing a repair bill of $600+ just for the board, plus labor.

On an XPS 13, the RAM is soldered in -- if it fails (which is what that error code means), the mainboard needs to be replaced. Try a reset first (unplug the system, remove the base cover, disconnect the battery from the system board and hold the power button for 30 sec). Reconnect the battery, replace the base cover and see if the system will power up. If the error continues and the system is under warranty, call Dell for repair. If it's out of warranty, brace yourself for a repair bill of at least several hundred dollars.

Waiting for the T5 screw driver. Will try and I hope it works. Else would be a big disappointment as , it has just over couple of months above warranty. Would never buy Dell again

(Solution for models with removable RAM sticks) · The issue you're experiencing is due to the CPU overheating, which causes the solder connections on the "SLOT A" memory RAM to become soft and detach from the motherboard. · When you disassemble your laptop, you may notice melted rosin or flux residue. · Unfortunately, there isn't a permanent fix for this. · One temporary solution is to apply pressure to the top of the RAM holders to try and secure a good connection, which might prevent the laptop from displaying the "2 amber + 4 white" error code. · However, the best option is to use "SLOT B" and upgrade the memory stick in that slot. I hope this helps! · Gosh
