Thinkpad X12 Detachable Touch Screen not working

[ich5555]

Hello,

i have replaced on my Thinkpad X12, the Systemboard and the Touchscreen, with a new one from Lenovo.

I put everything together and everything works, except the touchscreen (touch function) in Bios and in Windows.


Can the problem be that the UUID an Serialnr. are not assigned?

Has anybody a idea?



Thank You

I have it repaired. I pushed the on off Button Long and then i restart the Notebook and it works.
