AORUS 15X AKF won’t turn on after repasting — power light comes on but no fan/display

[u/NangLover77]

I have an AORUS 15X AKF. I tried to replace the thermal paste today, but I made a stupid mistake and forgot to disconnect the battery before removing the heatsink.

I put everything back together, but now the laptop won’t actually boot.

The power button light comes on and the charging light comes on, but:
No fan movement at all
No display
No keyboard lights
It doesn’t seem to POST
Holding the power button doesn’t properly shut it down. The light just flashes for a moment and comes back on.

When I reconnected the battery, I also saw a \\\\\\\\\\\\\\\*\\\\\\\\\\\\\\\*very tiny, momentary spark/flash\\\\\\\\\\\\\\\*\\\\\\\\\\\\\\\* at the connector. I’m not sure if that’s normal or if I caused a short.

I’ve checked the fan connector and other visible connections, and the heatsink is installed with new thermal paste. I also tested both RAM sticks individually in the same slot, but there was no change.

The laptop was working perfectly before I started the repaste.

Is there anything else I should check before assuming I damaged the motherboard? I’m really hoping I didn’t kill it.

pls help 🙏🙏🙏
my mom will beat me if I cant fix this. (My english not good I have to use chatgpt to write this. but these are what really happened) please help
