Lenovo X1 Yoga 1st Gen (model - 20FQ) - No Charging Stylus Pen
Hello, friends!
I need help with my Yoga 1st Gen (20FB000QUS). I upgraded the MoBo to have 16GB, so I bought the same MoBo (14282-2M LRV1 MB 448.04P15.002M) on Aliexpress, but with the X1 Carbon 4th Gen (20FBA05ECD). I managed to edit the BIOS with the Intel ME/TXE injector tool and clean the ME and add the correct Chipset codes, but the Stylus Active Pen is not charging power. I measured the voltage on the original Yoga MoBo and it is 3.341volts/3.351volts, but on the X1 Carbon MoBo it is only 0.5volts, not enough to charge the Stylus Active Pen. This is definitely some missing ACPI code in the BIOS that releases the voltage to charge the pen, but unfortunately I don't know how to solve this problem. If anyone can help me, I would really appreciate it!
