@Mahes99 Note that specific patterns of long and short blinks along with long and short beeps (where applicable) identify errors during the startup process.
Newer computers have two-part blink sequences with different color lights to indicate specific errors and you may click here and troubleshoot on your own, or check below:


Light and beep pattern - 2.2 (blink) - The main area (DXE) of BIOS has become corrupted, and there is no recovery binary image available. (Also happens when updating the BIOS.)

Solution: Perform BIOS recovery with external media (USB or CD-ROM). Go to HP Notebook PCs - Recovering the BIOS for additional information.
