The blinking pattern you’re observing (2 amber, 8 white) points to an LCD failure. Here are some steps to consider:
Check the Screen: Even if the screen appears to be working fine, there might be underlying issues with the LCD panel itself. Sometimes, subtle problems can cause this error code.
Reseat the LCD Cable: Open up your laptop (if you’re comfortable doing so) and reseat the LCD cable. Sometimes, loose connections can trigger false error codes.
Hold the Power Button: Try holding down the power button for about 30 seconds while the laptop is in Windows. This action can sometimes reset certain components and resolve the issue.
CMOS Battery: If the problem persists, check the CMOS battery. A dead CMOS battery can sometimes cause unexpected errors. If you need to replace it, ensure you have your Bitlocker key handy if you’re using Bitlocker authentication.
Motherboard: If none of the above steps work, it’s possible that the issue lies with the motherboard. You might need to consider replacing it.

Thanks for the info. The screen seems to be working fine, is there something else that might make the computer think the LCD is failing?
ETA: those codes are from the second link - those are error codes for tablets.

I have the same problem as you, but my device is precision 7540. I also contacted dell and got an answer that this is the motherboard fault.
And the solution to this problem is to replace a different motherboard (but I'm not sure these refurbished boards won't continue to have the same problem).

Hi All, I had a similar issue (2 amber and 8 white flashes) with my Latitude 5410, I thought I was going to need a new motherboard, but after holding the power button for about 30 seconds (Dell tech advised), this is while in Windows, the error code/lights when away. I hope they stay off. Thanks!

This also worked for me. The laptop had no other symptoms and was working fine. It just had the blinking lights. Dell latitude 5500.

be careful doing the 20 seconds power button hold. this resets the bios.. if you have Bitlocker authentication on, you will need your bitlocker key or you will be in trouble.. Also your bios will need to be fully reconfigured to the way it was, so if you are running a custom setup (eg, forcing descrete graphics, etc) then you will need to reconfigure this also

After trying everything above, I even tried removing the base and unplug and re-plug in the LCD cable. Still has the same issue.

I found this Diagnostic LED guide from the Dell website very helpful for a similar issue I was experiencing. Some of the links others have posted in this thread helped me find it. Here's a direct link: https://www.dell.com/support/kbdoc/en-us/000127927/a-reference-guide-for-latitude-notebook-and-tablet-diagnostic-indicators

That is not entirely true. That will only happen if your cmos battery is dead already. your essesntially draining residual power when you hold the button down.
