Lenovo ThinkPad X1 Tablet Gen 3 : cannot be used as a tablet
Obsolete BIOS/ECP with Missing Support for ‘no win button’ logon
(support Power + Volume up button combination to notify "CTRL+ALT+DEL")
Lenovo ThinkPad X1 Tablet Gen 3 (model 20KK) with Windows 10
Company forces the safety policy to No Win Button logon (right decision)
The hardware “Power + Volume up” to replace the CTRL-ALT-DEL is not working on Lenovo ThinkPad X1 tablet gen 3
I cannot use a screen logon to Windows 10 (inhibited by safety policy).
I can only logon when the keyboard is connected (to use hard CTRL-ALT-DEL)
> The Lenovo ThinkPad Tablet X1 Gen 3 can only be used as a normal laptop…
CTRL+ALT+DEL is implemented by the embedded controller firmware (ECFW, also referred to as ECP)
The issue was known and solved by Lenovo for ECP>1.06 on other tablets.
(see BIOS1.16//ECP1.08 was solving the issues and also BIOS1.54/ECP1.11)
I realize it was stupid to purchase and pay for a tablet and use it as a basic laptop.
This is frustrating and I thank you for your help to solve or bypass this.
