My laptop fx553ve.

Shows a black screen whenever i try to power it on.
i can hear click.
Fan turns on but not at full speed.
Power indicator LED is on.
Airplane mode led is on.
Hard disk is spinning silently–checked with a stethoscope , but the Hard disk access indicator does not turn on.
Battery led is on.
CapsLock led turns on when i press power button then turns off.
LCD remains black.

History- turned my laptop on successfully. After using it for some time, closed the lid. Open the lid after some time, power led is on but HDD access led is not turning on. Forced shut down. laptop is discharged. Tried to power it with AC power. Failed.

I have tried a other things.

Cleaning my laptop internally.
Reseating the Ram, HDD, fan, led, battery, etc.
Disconnecting the battery and tried to run it on ac power.
Running without CMOS battery, and then putting it back.
Doing a 3-2-1 discharge cycle.
Praying.

Currently i am letting it sit for the whole night. If you have any other suggestions, please share and help me.
