Hi @Rajeshmohangoel,

Welcome to the HP Support Community.
 

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

 

 The Caps Lock blinking 3 long and 2 short blinks on your HP Pavilion Laptop 15-cs2082TX is a diagnostic code from HP indicating a Memory failure.

Steps to Recover from BIOS Corruption

1. Try HP BIOS Recovery

This is the most effective method to restore a corrupted BIOS.

Steps:

1. Turn off the laptop completely.
2. Press and hold the Windows + B keys.
3. While holding those keys, press and hold the Power button for 2–3 seconds.
4. Release all keys and wait; the screen may stay black for up to 40 seconds.
5. If successful, you’ll see the HP BIOS Recovery screen.

Follow the on-screen instructions to reinstall or recover the BIOS.

2. Run Extensive Test -

1. Hold the power button for at least five seconds to turn off the computer. 

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key. 

3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests. 

4. Click Extensive Test.
 

I hope this helps.

Take care and have an amazing day!
