laptop power light goes on and straight off

[cryptedmods]

Since today the laptop started to have issues it started with HDD not being found, we tried figuring that out but then suddenly laptop turns off and has issues turning on it gave us a CAPSLOCK light thats blinking but after that it is not turning on at all when we press the power on button the power lights goes on and after 2-3 seconds it goes off we are out of options, we openend the whole laptop disconnected everything reconnected everything but still nothing our last option is placing RAM in another port to see what happens if it works but we doubt it works, so hopefully someone can help us solving this problem.

Hi @cryptedmods,

Welcome to the HP Support Community.
 

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

Based on your description, your HP laptop is showing signs of a critical hardware failure, possibly related to the motherboard, RAM, or storage subsystem. The progression from “HDD not found” to Caps Lock blinking, followed by no power-on response, is a strong indicator of a deeper issue.

Let’s walk through a structured recovery approach:
1. Interpret the Caps Lock Blink Code

HP laptops use Caps Lock blink codes to indicate hardware faults.

• Count the number of blinks before it pauses and repeats.
• Common codes:
  • 1 blink: CPU failure
  • 2 blinks: BIOS corruption
  • 3 blinks: Memory (RAM) issue
  • 4 blinks: Graphics failure
  • 5 blinks: System board failure

Let me know the exact blink count if it still shows.

2. RAM Reseating Test (Only to be handled by Experts)

You’re right to try swapping RAM slots. Here’s how to do it safely:

• Remove all RAM sticks.
• Clean the contacts gently with a dry cloth.
• Insert one stick at a time into each slot and try powering on.
• If you have two sticks, test each individually in both slots.

If the laptop powers on with one stick, the other may be faulty.

3. CMOS Battery Reset (Only to be handled by Experts)

If accessible:

• Remove the CMOS battery (coin-sized battery on the motherboard).
• Wait 5 minutes, then reinsert.
• This clears BIOS settings and may resolve boot issues.

4. External Display Test 

If the screen is black but the system powers on:

• Connect to an external monitor via HDMI.
• Check for display output.

I hope this helps.

Take care and have an amazing day!

it doesn't do the Capslock blinks no more, i already tried the RAM testing didn't do anything either, so far i haven't found a CMOS battery on the MB, and its not an issue with the monitor/external monitor. it doesn't turn on at all and its fans are not working either so no sign of turning on at all
