Hi
Tell us the number of times and the repeated cycle, EG:
https://support.hp.com/us-en/document/bph07107
Power button LED blinks 5 times with 5 beeps | Memory | Reseat memory DIMM modules. If the problem is not resolved, contact support to resolve a possible RAM or Main-Board failure. |
Power button LED blinks 6 times with 6 beeps | Video Card or Graphics | Reset the graphics card (if applicable). If the problem is not resolved, remove other accessory cards, and replace the graphics card or Main-Board. |
Power button LED blinks 7 times with 7 beeps | Motherboard or Main-Board failure | Contact support for possible Main-Board replacement. |
Power button LED blinks 8 times with 8 beeps | BIOS or CMOS problem (ROM) | Perform BIOS recovery with external media (USB/CD-ROM). |
OR
BIOS | 2.2 | The main area (DXE) of BIOS has become corrupted and there is no recovery binary image available. Also happens when updating BIOS. | Typically no steps needed. 1. Allow the system to complete its updates and changes. 2. If updates are stalling, attempt Sure Start Recovery. |
BIOS | 2.3 | The embedded controller policy requires the user to enter a key sequence. | 1 Follow any prompts given. 2 If issue persists, attempt Sure Start recovery. |
BIOS | 2.4 | The embedded controller is checking or recovering the boot block. | 1 Allow the computer to attempt to recover the BIOS. 2 If after several minutes the issue persists, attempt Sure Start recovery. |
