@nitishmehra this " my fan is travel in high power" could point to a BIOS issue.

Start off with the easy things. Disconnect the power from the computer by unplugging the power cord from your computer. Disconnect all external devices from the computer. Remove the battery Now hold the power button depressed for about 30sec-1min. Reapply the AC power adapter and see if your computer does show any sign of life.

• Emergency Key Method (No USB needed):
• Turn off the computer and plug in the AC adapter.
• Press and hold the Windows key and the B key at the same time.
• While still holding those keys, press and hold the power button for 2 to 3 seconds.
• Release the power button but keep holding Windows + B until you hear a beep or the HP BIOS update screen displays.

If none of that works you will have to start with the basic troubleshooting steps. Next check your power supply. Make sure it has the proper voltages. Check to make sure that connectors are not bend etc. Check the DC-in jack of your laptop. Make sure there is no corrosion, debris etc. that prevents it from working. Clean it of any debris etc, use a few puffs of air to clean it out. If none of this works, get a ammeter and see if your laptop draws any amperage from the charger. After that, you need to check and see if your motherboard even gets power. For that of course, you need to open it up. Post Some good pictures of what you see. That way we can see what you see.

Of course, it is also possible that this is a bad RAM module. So remove the RAM, clean the contacts with a pencil eraser. Do it gentle so as to not destroy the module. Replace it and restart. If you have more than one module, remove it and just leave one connected.
