Notebook flashes 5 times, which means general motherboard error. What makes me suspicious is that the fan starts up briefly and the power button is lit, so the NT should be fine. Ram and HDD I have expanded, but the error is always the same. Drive goes on and on, the battery is also charged.

Capslock flashes 5 times

my question what is broken in motherboard?

Thank you

When fan start and stop after a while, something is wrong and power automatic turn off to protect circvuit. One way to diagnose this problem is disconect one by one until power supply is ok.

hello, thank you
When I start the laptop, the fan stops running for a moment then it's normal but when I let the laptop off after 5 minutes of fan starts so far so well

I do not get monitor, I also have a sink, battery replaced, did not help
