For anyone still needing a solution we found on the E5540s that if you go into BIOS > Power > USB PowerShare and toggle that option on that this issue is resolved completely. The suggestion by @AardvarkTech does work great, but it has to be changed for each dock that the system is connected to so in a hoteling environment still caused issues. UPDATE: Some of our machines are still having the issue after making this change, but it did fix it for some of them. We have just starting setting Windows to never sleep while connected to power and that resolves it completely. Answer from sradford09 on dell.com

Dell laptops use a combination of amber and white LED flashes to indicate specific system issues. The 1 amber and 8 white LED code has been observed across multiple models, including Latitude, XPS, and Dell Plus systems. While this code is not always listed in standard fault code references, it often points to a BIOS-related issue or, in some cases, a motherboard fault. Basic Troubleshooting Steps Connect the AC Adapter DirectlyIf your system is connected via a docking station, try powering it using a direct AC adapter. Some users have reported successful boot after switching from dock to direct power. Perform a Power DrainDisconnect all power sources, then press and hold the power button for 30 seconds. Reconnect the power and try turning the system on again. Update the BIOSIf the system boots, update the BIOS to the latest version. This has resolved the issue on several models: Dell Plus systems XPS systems Next Steps If the issue persists after these steps, it may indicate a motherboard failure or a deeper firmware conflict. We recommend contacting our support team for further assistance. You can use the Get Help Now chat feature located at the bottom right corner of this page. Or, you may reach out to a trusted technician for a hands-on diagnosis. Please see this video for additional general No Post Troubleshooting.

I was wondering if anyone knew what it would mean if I blinks between lights 2-3-4 and then just 2 and 4. So 1 is power, 2 is storage, 3 is battery and 4 is network.
