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.

(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

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.

Hi, pattern 2 amber, 4 white is for Memory or RAM failure. First thing i would try is reseating RAM. Second thing i would do is flea power release: Flea power is the residual static electricity that remains on the computer even after it has been powered off and the battery has been removed. The following procedure provides the instructions on how to conduct flea power release: Turn off your computer. Remove the base cover. Press and hold the power button for 15 seconds to drain the flea power. Replace the base cover. Turn on your computer. Dell forgot to add up one step for this ( its to unplug battery doing flee power release) Third thing i would do is hold power button for 30 seconds ( more on link bellow): https://www.dell.com/support/article/si/en/sibsdt1/sln304892/how-to-reset-real-time-clock-rtc-to-recover-your-dell-portable-system?lang=en Also try this if your product is supported: http://dell.to/2u4vSud The HDD and DATA should be unharmed as it doesnt have anything to do with above troubles.
