Reasons Behind HP Laptop Caps Lock Blinking Issue

When faced with this problem, here are some things that could be causing this problem:

  • Broken laptop charger – A broken charger will send the wrong amount of voltage to your HP laptop, which can cause power problems. If it is old or corroded, you should consider replacing it with a new one.
