Which expension cards cause battery drain even laptop is shutdown?

Hello,

I’m using Framework Laptop 13 (intel i5-1240p),
As far as I know, some expension card(such as usb-a, hdmi, dp) can cause battery drain even when the laptop is shut down,
is the issue still present? which card are affected?
Ethernet? SD/microSD reader? Storage?

Thanks~

OK, I bought the Ethernet card, the LED keeps blinking if LAN is connected even when laptop is shutdown,

so I guess Ethernet expansion card also has the battery drain issue.:worried:
