HP 15-ay025ds laptop -- The unit will not power on. The caps lock key flashes a 2.1 pattern (2 long, 1 short) but I have been unable to find what this code indicates. I have removed the power supply and battery and pressed the ON-OFF key for 1 minute, then restored power. There was no change. I also reseated the RAM but that made no difference.
Solved! Go to Solution.

Welcome to the HP Forums 🙂
I would like to take a moment and thank you for using this forum, it is a great place to find answers.
As I understand, the laptop won't power on and caps lock light is flashing.
No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:
When was the last time it worked fine?
Have you made any hardware/software changes?
Let's try these steps from the article: Computer Does Not Start and Emits an LED or Beep Code
You could refer to HP Guided Troubleshooter.

Everyone else is just as clueless as I am, apparently. Why does HP enable the error flashes and then not post anything to indicate what they mean? I've found a couple of charts but none list the 2.1 pattern.

I had done most of the items mentioned in that article. I went ahead and reseated all connections within the unit and, now, it powers on. I'm not sure which one was loose (possibly the data ribbon for the hard drive). At any rate, it powered on, ran an automatic check of the HDD, and loaded Windows. While I haven't seen the 2.1 pattern mentioned anywhere, perhaps it denotes an error with the hard drive. Thank you for your assistance.
