Hi @T2Pinder,
Welcome to the HP Support Community.
Thank you for posting your query. I will be glad to help you.
I understand that you are getting the blinking Caps Lock light on your HP laptop, combined with a black screen and no boot, typically indicates a hardware or firmware issue. The number and pattern of blinks are a diagnostic code. Here's how to troubleshoot it:
Step 1: Identify the Blink Code
Count the number of long and short blinks from the Link shared and see what kind of blink you notice: HP Notebook PCs - Computer beeps or a light blinks during startup | HP® Support
Let me know the exact blink pattern if you're unsure what it means.
Step 2: Hard Reset
- Disconnect the power adapter.
- Remove the battery (if removable).
- Press and hold the Power button for 15 seconds.
- Reconnect power (without battery if removable) and try booting.
Step 3: BIOS Recovery
If the blink code suggests a BIOS issue:
- Hold Windows + B (or Windows + V) keys.
- While holding, press and hold the Power button for 2–3 seconds.
- Release the Power button but keep holding the keys for 10–15 seconds.
- If successful, the screen should light up and begin BIOS recovery.
I hope this helps.
Take care and have a good day.
