Hy, today i tear apart my laptop and put it back up toghether, new cooler paste and all but it will not turn on, not even the led for charging. when i plug in the battery or the charger it starts a beeping sound and it comes from the procesor( the procesor is integrated in the mother board, it's soldered to it). i've tried pressing the start button for 30 seconds, another ram chip and some tricks but still wont power on at all.
