Spectre X360 14-ef2052TU

[MoeezRehman]

When powering up the Spectre X360, there is no display, and the caps lock light indicates a long blink followed by three short blinks. Could this be a display issue or a motherboard issue?

Hi @MoeezRehman,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The pattern of blinks on the caps lock light you're describing— one long blink followed by three short blinks— is a diagnostic code that HP laptops, such as the Spectre X360, use to indicate specific hardware issues. Typically, these blink codes are meant to help identify problems with the computer's hardware components without needing to fully boot up the system.
