Thank you., I will try it when I have the device

Thank you.
According to the Lenovo T480s schematic in LPC,
I understand the four contacts LPC_AD[3:0] that lead to the MEC1663-WC_WFBGA144.
LPC_AD0 >LPC_AD[3:0]
LPC_AD1 >LPC_AD[3:0]
LPC_AD2 >LPC_AD[3:0]
LPC_AD3 >LPC_AD[3:0]

Hello, the Lenovo unlocking wizard has struck again. Is this the short circuit between JLPC 1 LPCCLK_DEBUG_24M and 3 GND1 from the schematic Lenovo T480s or other contacts.
I haven't quite got the hang of which LPC bus connections need to be shorted to achieve this.

@@M._.x._.Power3 Thanks for the message, yes that is of course much faster than desoldering the BIOS chip and working with the Auto-patcher from Knucklegrumble. The measuring tip is therefore directly connected to a GND point on the motherboard.
