It isn't documented in the manual for that system, but 1,4  is usually a faulty battery error.  Shut down, disconnect AC power and remove the base cover.  Disconnect the battery from the system board and power up on AC only. If the flash sequence ceases, the battery needs to be replaced. Answer from ejn63 on dell.com

Dell XPS 15 9575 4 amber 1 white light blinking, won't turn on unless plugged in while blinking
4 amber 1 white means a bad battery 90% of the time. The pattern code indicates that the main battery cannot power the system. Seeing that the battery degraded substantially as well, you're likely looking at needing a new battery. If it's under warranty hit dell up and if not i'd buy a new genuine one from ebay (dell part number is TMFYT) More on reddit.com

The blinking pattern you’re observing on your Dell Inspiron 3558 (4 times amber followed by 1 time white) indicates a Battery Issue. Since your laptop is an older model, it’s possible that the battery has reached the end of its lifespan. Battery Replacement: You’ll need to replace the battery. You can find compatible replacement batteries for your Dell Inspiron 3558. Here’s a link to a replacement battery that you can consider. Battery Report Check: Create a battery report to check the status of your current battery. Open a Command Prompt window (search for 'cmd' in the Start menu). Type the following command and press Enter: powercfg /batteryreport This will generate a battery report. Locate the report file (usually saved in your user folder) and open it. Compare the Design Capacity value with the Full Charge Capacity value. For a healthy battery, these values should be nearly the same. Temporary fix/Workaround: Hard Reset Turn off the laptop. Disconnect  the AC adapter and remove the battery or simply remove the base cover and disconnect the battery cable. Disconnect all devices such as USB drives, printers, webcams, and media cards (SD/xD). Press and hold the power button for 15 to 20 seconds to drain the residual power.

r/Dell on Reddit: Dell XPS 15 9575 4 amber 1 white light blinking, won't turn on unless plugged in while blinking
January 21, 2020 -

I've had my XPS 15 (2-in-1) for about 2 years now and it's been a great laptop so far. Recently, my laptop indicator light (front of the laptop, right below touchpad) has been blinking in a specific pattern (4 short amber, 1 long white). While it is blinking, the laptop will immediately shut off if not plugged in. In addition, my battery life has degraded somewhat significantly (from 75 to 38 mWh). These two combine to make it quite difficult to use my computer as a laptop since I am constantly looking for outlets in case this issue arises. Has anyone else had this issue and if so, have you found a solution? I'm going to try taking it to my local computer repair shop but in the mean time I thought I'd ask. Thanks!

Fix Dell Laptop LED Blink Code 2 Amber, 4 White (Memory Error) | DELL Technologies
March 31, 2026 - Dell LED blink codes use a two-group pattern: first amber count, then white count (e.g., 2,4). Check your model’s LED table to confirm meanings and follow the recommended actions for any other pattern (e.g., 2,3 = no memory detected, 2,1 = CPU error).

October 14, 2024 - If both modules test bad in one socket but not the other, replace the system board. If your system has DDR5 memory, there is a non-removeable 8G module on the mainboard. Try removing the second module (that one is socketed) and try again. If the error is cleared, replace that module. If the error persists with the module removed, the onboard RAM is bad. Replace the mainboard. ... The blinking amber and white lights on your Dell Inspiron 5620 laptop indicate a diagnostic code.
