Alien head power button lighting up

Had this about 6 months and don't remember the power button ever lighting up. Yesterday I noticed it lit up blue. A short time after that it froze and got the blue screen of death.

Today it lit up again, then went off, and then it started blinking I think 4 red and one blue. Did that for a little while then it looked like purple, like both blue and red were on. As I'm typing this it switched to red for a second or two and now back to looking purple.

I ran the diagnostic test on the Dell website and it passed the test, with no failures. So I don't know what's going on.

I found this blink code, I don't see a 4,1 pattern so possibly it was three red and one blue? I don't know. That would be an RTC failure. Is there any way to confirm since the diagnostic test passed?
