My Hp EliteBook laptop is not run on. The caps lock, power button, and the charger indicator light are blinking repeatedly, and the fan is running at high speed. I need help solving this issue.

Hello.

The blinking lights during startup are a way to identify the likely problem that prevents the laptop from starting.

HP has a document which lists the blink codes:

Your laptop probably requires servicing because it doesn't start.. If the problem is simple - e.g. bad memory module or similar easily replaced part then you can do it yourself. In any case you can either take the laptop to a local HP Service partner and let them diagnose the problem properly. Most generic laptop/computer repair shops may also be able to pinpoint the problem and fix it.
