Precision 7550 - Memory Issue - 2 Amber 5 White. Multiple Machines - Different Ram Slot fixed
I’ve had this issue for over a year and it seems to pop up around BIOS updates. A co-worker and I both had it happen last week, and each of us has had it happen once this week. Our solution has been to pop a stick of RAM out, turn on the machine and it recognizes the memory change, and then turn it off to put the stick of RAM back in. This week is odd because there are no BIOS updates listed in Dell Command, and we’re on 1.21.0. Our RAM sticks are under the back cover. We haven’t done anything with the slots under the keyboard. It will be interesting to see if your movement to under the keyboard is a long term solution, or if it’s just a variation of what we’ve been doing where the laptop recognizes a memory configuration change. The new laptops our company has been rolling out are much slower than the 7550, so an occasional 10 minute “RAM swaparoo” isn’t that bad when looking at the alternative. More on reddit.com

r/Dell on Reddit: Precision 7550 - Memory Issue - 2 Amber 5 White. Multiple Machines - Different Ram Slot fixed
May 17, 2023 -
So Today I had 2 different 7550s not turn on, both had the 2 amber 5 white error code. So we tried taking the ram out and testing one stick at a time and in different slots underneath and no go.
The fix was to move both ram sticks to under the keyboard and then it boots with no issues.
Its weird that I had two different laptops in two different offices experience this same issue today. Is there any bios updates that pushed out that could have caused this?

This worked for me. I had to move them to behind the keyboard. Just disconnecting one or the other didnt work.

r/Dell on Reddit: Dell Precision 7550 not starting after CMOS battery replacement
October 14, 2023 -
I'm trying to get this Precision cleaned up and reset. After resetting bios with a CMOS pull, it won't start and will only show a amber light each time the power button is pressed. I suspect there is a reset procedure that Dell technicians have to do after a CMOS reset that I'm not savy to. Best advice I've seen so far is flashing the bios chip direct which is really not something I'm equipped to do (link if you're interested https://youtu.be/_jwLAa9pMU0?si=h4OBXArMXCNJ4B2X)

Hi, the video you linked here is the repair of my laptop by Sorin Electronics, following the repair the machine worked fine for 7 or 8 months only for the exact same issue to happen again. Seems there is a real issue with the bios on these laptops. Interested to know if you managed you to resolve the problem with your laptop without flashing directly.
