The reset procedure actually is to disconnect the battery and the adapter. Then press and hold down the power button for 30 seconds. Then reconnect everything and try to reboot. Run a diagnostic procedure by tapping F12 immediately at boot. If it runs properly watch for any errors. That flashing amber light means a low battery charge. It is possible that the battery needs to be replaced or that the adapter is not charging the battery properly. If the adapter light stays on then a short is not likely. If possible try another Dell adapter. It is also possible that the DC jack is having problems and needs to be replaced. Least likely cause, the MB charging circuit is not working.

Ok, just tried it and still nothing. I can't get it to power on. All I get it the little power light up at the top by the battery life light. Nothing happens. Does that mean that I need a new system board?

r/Dell on Reddit: XPS 15 (9530): Power button light turns on for a few seconds, then shuts off
November 28, 2022 -
After enabling the external USB ports in the UEFI setup menu, my laptop fails to boot. Pressing the power button results in the button light turning on for (pretty much exactly) 5 seconds, and when on battery power, one of the five battery LEDs briefly flashes orange. There is no display, fan or keyboard activity. The exact same behaviour occurs when starting the laptop in emergency BIOS recovery mode (inserting the AC adapter while pressing the End key), except that the power button light blinks (again, for five seconds).
I’ve tried clearing the NVRAM by removing all power sources and draining flea charge, and also removing the RAM, SSD and WiFi cards. The RTC battery was dead, but replacing it did not help.
Three questions:
-
I suspect that the cause is a fried power supply circuit. Does this seem plausible, given the above information?
-
Are there any other troubleshooting steps I should try? Here is the motherboard schematic, if that is of any use. I have access to an oscilloscope, but my electronics knowledge is elementary at best.
-
As a last-ditch effort, I’m thinking of trying to reflash the BIOS in emergency flash mode. However, I’m unable to extract the .hdr and .rom files from the A08 Windows executable (“Error: Unable to load driver). Would one of you be able to extract the files and PM them to me?

Good day, You'll need to do a couple things in order to narrow this down: 1. Pull the battery 2. Unplug the power 3. Remove the memory, hard drive and any cards like WIFI 4. Plug the power only back in Try to power on the unit. If the unit still shuts down after 3 seconds, it's a motherboard problem. If it doesn't shut down anymore, you'll need to add back in one of the components I mentioned above, one at a time and test power after each one; to find out which one caused the issue. Process of elimination basically. If still under the purchased warranty, click the 'Get Help Now' icon on the right to start a live chat session.

Hi, · There may be a problem with the power connector port (aka DC-In jack) in the laptop. · Sometimes the inner +ve conductor of the jack can fail intermittently causing no power to be received by the motherboard from the charger. · Here's the owner manual for the laptop. Go to p.28 to view the procedure to remove /replace the DC in card to gain access to the cable plug and just disconnect the power port cable plug from the card and then connect the charger to the power port. · Use a voltmeter to measure the voltage on the red and black wires of the plug. If there is 19V DC when measured at the port's cable plug, then gently move the charger's plug up and down and side to side (not in and out) inside the power port to see if the voltage remains constant or comes and goes. · If it comes and goes the jack is faulty and will have to be replaced as it cannot be repaired. · Search online for 8GJM9 to find suppliers that suit you best.

Check this link. http://en.community.dell.com/support-forums/laptop/f/3518/t/19458916.aspx Answer appears to be removing and reinstalling the CMOS battery inside the laptop. You will then start with a 'clean' BIOS in the CMOS chip. The CMOS data can become corrupted. Best to try some of the other recommendatrions first, as they don't involve taking the laptop apart.
