HP pavilion died and won't turn on or charge

[Blueberries1]

Hi, my laptop was running low on charge so I plugged it in however it still died and now the charger won't work (I've tried two different ones) and whenever I press the power button the light by the charger flashes three times but nothing else happens and the laptop stays black.

Dear @Blueberries1 

Welcome !

Please, refer to this official article which describes your case scenario.

This looks like hardware issue and you may need to check the memory.

Reseat the memory. See the section Re-seating memory modules in a notebook for more information.
