Notebook ticking sound and not turning on

[Kartheek9]

My HP envy 15 inch won't boot, the power button is flashing on and off, plus there is ticking sound.

Nothing showing on the screen.

Power light on the other side is blinking.

Before  this I have updated my ram size to 8 GB from 4GB and made some software updates.

Usually if you are seeing Power light on, tick sound,power light off. Power light on,tick sound,power light off- the laptop is trying over and over to power on but something is stopping it almost immediately.

After the ram upgrade has the laptop booted successfully?

Have you tried removing the new ram to see if any difference?

Have you tried a power reset/hard reset?

Hi Cherylg,

After the ram upgrade has the laptop booted successfully?--> yes it was.

Have you tried removing the new ram to see if any difference?--> No, not tried to open.

Have you tried a power reset/hard reset?- yes. i did by removing the battery and pressed power button for long time (more than 20 sec ) and after inserted battery again but no response still issue going the same way 😞

i would like to know, is this issue very serious one ?

Please help me out from this issue. i am more panic&tense about it.

thanks,
