Hi @Krishna_kanth,

Welcome to the HP Support Community

I'd like to help!

I understand that you are facing a blinking Caps Lock issue with your  HP Notebook - 15s-Du1052tu. Not to worry I will help you to get a resolution to resolve the issue.

For better clarity and to assist you better I would require more information regarding this:

• Did any hardware changes take place on the laptop recently?
• Is the power cord connected directly to a working wall outlet?

Meanwhile, I recommend you perform the below steps to isolate the issue and arrive at a fix: 

Step 1: Hard reset 

• Power off the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.
• Power ON the laptop and check.

Step 2: Recovering the BIOS

• Turn off the computer, and then connect the power cord.
• Press and hold the Windows key and the B key at the same time, and then press and hold the Power button for 2 to 3 seconds.

• Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.
• If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next section to Recover the BIOS using a USB recovery drive.
• If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the Power button for only 2 to 3 seconds.
• If a BIOS recovery message repeatedly displays, continue to the next section to Recover the BIOS using a USB recovery drive.
• If a message that the computer improperly shut down or a boot problem is detected displays, follow the on-screen instructions to resolve the error.
• If Windows starts, update to the latest BIOS version. Go to HP Notebook PCs - Updating the BIOS for more information.
• The HP BIOS Update screen displays and the recovery begins automatically.
