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.

Help my Dell laptop won't turn on I've done everything said from the internet
Dell laptops have issues with the power regulation chip. What you need to do is pull the back cover off and unplug both the main battery and the CMOS battery. You need to be very very careful removing the CMOS battery. Do not pull the battery out by the wires. I find it’s best to use a plastic pry tool of some form, whether it be a spudger, old credit card or some other thin semi-semi blunt plastic tool. If you rock the two sides back and forth then push out the connector down the center, it will come out. The CMOS battery looks like this: https://guide-images.cdn.ifixit.com/igi/rWTpWLLvSdZ36TQU.large Once you have both batteries unplugged, hold the power button for 60 seconds. Yes, really, 60 seconds. Plug both batteries back in and plug in the charger, then attempt to turn the laptop on. If all went well, the CPU fan should spin over a few times before the machine finally boots back up. Put the cover back on and you’re done. Source: I’ve been working in IT Support/Management with Dell as our main vendor for the last 12 years. More on reddit.com

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:

  1. I suspect that the cause is a fried power supply circuit. Does this seem plausible, given the above information?

  2. 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.

  3. 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?
