Quick summary of the symptom observed by : after a long power-off the power LED and wireless LED flash 3–4 times, then the machine completes POST and boots normally; subsequent immediate restarts are fine. That pattern suggests the firmware/embedded controller (EC) is briefly failing to initialise after a long discharge, but several simple diagnostics will narrow the cause.

Recommended troubleshooting steps (safe, ordered):

  1. Power-reset the system: unplug AC, remove the main battery, hold the power button for 15–20 seconds to discharge capacitors, then reconnect power and test. Expected: if the EC was stuck, the flashes stop.
  2. Boot on AC only (battery removed): if the flashes disappear while on AC only, the removable battery or its charging circuit is a likely suspect. If flashes persist, the issue is on the motherboard/firmware side.
  3. Reseat accessible modules: with power removed and ESD precautions, reseat RAM and the Wi‑Fi card and its antenna leads. Loose modules can cause short, intermittent preboot errors that show as LED blinks.
  4. Run full hardware tests: use the laptop vendor diagnostics and run memory and storage tests (as @Begginnerdev suggested). Also check SMART data and run an extended memory test if available. Clean test results reduce the chance of a failing component.
  5. Check firmware: note the current BIOS/UEFI version and consider an official update only if the vendor notes a relevant fix. Firmware updates carry risk; follow the vendor instructions exactly.

Cautions and final notes: if still under warranty, contact HP before opening the case. Maintain regular backups while this intermittent behavior appears. If the blink pattern grows in frequency or leads to failed boots, service is recommended since persistent preboot blink codes can indicate failing motherboard components or EC firmware faults—otherwise it can sometimes remain an intermittent, noncritical POST quirk as noted.

After reading over a few documents with HP; I have not discovered any solutions that stand out.

You might want to give a try to see if it finds something.

My thinking is that this may be normal behavior - a system-level POST (Power-On Self Test). Use the HP diagnostics as Beginnerdev suggests to see if they determine there is a problem. If not, then ignore it would be my recommendation.
