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. Connect the AC adapter and battery. Turn on the computer.If you still need assistance, please contact support by clicking the ‘Get Help Now’ button located at the bottom right corner of the page.

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!

Hi Tempwfox519, Good work on troubleshooting. We will have to check the status of the adapter in BIOS; if the adapter is not detected properly the system will continue to receive power but will not charge the battery. Please follow the steps mentioned below to check if the adapter is detected properly. Start the computer by pressing the power button Press the F2 key 2-3 times You will now be on the BIOS screen Under the Main Tab look for the option that says AC Adapter Type If the Adapter Type says Unknown or None with the adapter plugged in. Reconnect the adapter to the machine and if the status now shows as Unknown then the AC Adapter needs to be replaced.

Hello…thanks for the quick response. I tried what you said. The BIOS states 150W under AC Adapter Type. I also unplugged it to see if the BIOS detected a change, and it did…it stated NONE. So it seems to be detecting ok, right? Something I might not have said in original post is that the light continues to blink whether running on AC power or Battery power. While plugged in, the battery meter always states 'a percentage' 'plugged in' 'not charging'… but battery seems to be charging. Current state is [96% available (plugged-in, not charging). I would think the battery should be a lot less than this by now if not charging. Strange. I just unplugged the battery with the system running to test the battery meter on the battery…shows all led lights lit. However, when I just plugged the battery back in, a Windows message appeared stating 'The model number for the primary battery is non-recommended. The battery cannot provide sufficient power to run the system on battery mode. Please insert a Dell battery for best system operation.' I would had never seen this unless I would have unplugged and replugged the battery with windows running. The original battery and the battery I just purchased are both from Dell. They are 'Dell Battery Module, Type R795X Rating: 11.1V Capacity 90Wh. Hope this helps. Sounds like a system/bios update issue of not detecting the battery properly, right? Thanks again.

r/Dell on Reddit: Inspiron 16 7610 stopped powering up. Giving 4 amber 1 white flash then flashing amber continuously . Help?
March 27, 2025 -

So I had reinstalled windows to my laptop. Left it for a week or so. Now I’ve come back to it there’s no boot showing, no display, no fans running. Battery is not charging when I have charger plugged in. And when I try to start it with just the battery , it just stays solid white. I have tried everything I seen online including disconnecting the battery and draining the power. I have disconnected the battery underneath, and plugged in the charger as seen in the video that is how i am getting the amber and white flashing . Any clues on what this could be? Getting 4 amber flashes then 1 white , then just continuous amber. And then I press the power button the keyboard just flashes a couple times as seen in the video. Any ideas would really help me out as all my works on there lol. TIA
