Computer powers on but does not boot, HP support does not explain what component to replace

[Bill_Hew1ett]

Hi, my laptop has had multiple issues before, and now it has a booting issue. When the power is turned on, the power light turns on, the fan turns on at full power, and the caps lock key flashes in a pattern of 5 long flashes and 3 short flashes. I located the HP beep code page and found the code that matches my pattern (available here), but it does not clarify what component needs to be reseated. Does anyone know what component that would be?

Hi @Bill_Hew1ett,

Welcome to the HP Support Community!

For this system, the 5 long red flashes followed by 3 short white flashes (5.3) indicate that the BIOS cannot reach a required hardware component within the established time limit. HP does not associate this code with one specific component such as RAM, SSD, CMOS battery, or the Wi-Fi card.

This is also why the troubleshooting instructions differ from the 5.2 and 5.4 codes.

Since the laptop is not reaching the BIOS or displaying anything, I would avoid randomly reseating internal components. The appropriate component to inspect depends on the specific hardware configuration of the OMEN.

You can try a complete power reset first:

1. Turn the laptop off and disconnect the AC adapter.
2. Disconnect all external devices.
3. Press and hold the power button for about 15–20 seconds.
4. Connect the AC adapter and try starting the laptop again.

If the 5.3 blink code continues, the next step is hardware diagnosis. The safest approach is to use the model-specific service documentation or have HP/authorized service diagnose the hardware rather than replacing parts based solely on the blink code.
