Laptop stuck at hp logo window

[J1200pp]

I had to force shutdown the laptop and after that i tried to start the lap. But it is stuck on this window which shows the hp logo. 

My inbuild keyboard is not working. So currently I am using a usb keyboard. And it is not turning on either. But my usb mouse is working. 

Pls help

Hi
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).
AND/OR
HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics Windows is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures. HP PC Hardware Diagnostics Windows comes pre-installed on new HP computers, but if not on yours, download here:- http://ftp.hp.com/pub/softpaq/sp93001-93500/sp93457.exe

OK you may then have a scrap laptop.

Because with NO OS  installed the onboard keyboard should still work to get into the BIOS etc.

ESC and F???

EG:  --   Hopefully one of these documents will cover (and solve) your problem...

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.
The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup to complete the recovery.
HP BIOS Update recovery in progress

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 step to install a BIOS recovery file from the HP website.
If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the button for only 2 to 3 seconds.

Therefore if the POST and BIOS are borked then just dis-assemble Johnny 5 for spares.

Sorry brother. I have found the problem. My cousin inserted a sd card to the laptop while it was turned of.

I think that was the reason for the problem. Because after i removed it the system turned on just fine.  

 again sorry for your time.
