Hello, same here the sd card board was the issue, clean the oxydation with flux and reflow both capacitor and realtek chip. Quivk diagnose, turn on, it make beep , unplug the flzx between motherbard and the sd card board, and the beep sound disappear.

thanks YOU brother

It's my opinion that all volt and signals should be checked with dso while hearing the 2beeps.

Thanks for your suggestion.🙏 All will be ok before the beep including coil voltage. At beep little changes will happen but all major voltages remains ok.

I already experience this trouble long time ago thats why i forgot what i made, the problem occurs when the side board is connected, i had disable 3 pin and work fine whith sound and not freezing

[@Pavithralaptopcare]

Thank you for the reply. The IO board contains the speaker connection. can you tell from which connection's 3 pin you have disabled? because intel and amd ideapad series are almost same. I will try a solution according to your suggestion.

I forgot what pin i disable, i put a Scott tape to disable pin on connector

[@Pavithralaptopcare]

ok. Thanks again. I will get back to you regarding these pins.

i found that. the pin no. 3 is for beep which is connected to IO(EC) PIN NO. 32. Yes, IO is doing its work. it indicating the issues through the beep. if we disconnect this, we can avoid the beep. but issue remains same.

Solved. If any issues with the pch connected connectors then issues will occur. means beep sound. 2 beep indicates the any weak signal in +ve or _ve path. for me, sdcard path was the issues. cleaned and resoldered the path. problem got solved.
