I have tried removing battery and AC power charger to reset laptop by holding the power button for few seconds.  After connecting the charger back it didn't work. Also tried removing CMOS a battery and reseating the RAM still the same result. There was no beep sound only blue light blink in charging port. no fan sound or nothing.

@zyan,

Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. I read your post that you have an HP Pavilion DV2000 notebook and you are having issues with booting the PC to the desktop. No worries, I'll be glad to help you.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any software or hardware changes on the PC before the issue started?

Did you try to do a Hard reset on the notebook?

Are you using the original charger that came with the PC? Have you tried to connect the laptop to a different wall outlet.

In the meantime, let's try these steps here: 

Perform a Hard reset on the notebook: 

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

1. If Windows is open, click Start and then Shutdown.

If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

2. With the power off, disconnect the power cord from the back of the computer.

3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

4. Reconnect the power cord and turn on the power.

Next thing, I would suggest here is to follow the steps suggested in the support document for - HP Notebook PCs - Computer Does Not Start (Windows 10)
