I have a Pavilion 15-ab157nr I purchased back in April 2016. Because it's been four years, my warranty has expired. A few weeks ago, I tried to turn on my laptop, but it failed to boot up and gave me a 5.3 blinking caps lock error code, indicating that "the embedded controller times out waiting for the BIOS." Others seem to have had this problem, so I found a thread with this link and went through the procedure of making a recovery BIOS on a USB, but nothing seemed to happen when powering on the laptop while holding Win + B or Win + V.
I have had no luck finding any other possible solutions using the virtual support agent or Google and can't seem to find a phone support line.
