Shutdown-Problem Thinkpad S440AY Windows 10 (Education)

Since I have updated my S440 from Win 8.1 to Win 10 Education I have some problems with the shutdown.


If the notebook is on for a short time, shutdown works normally. If it is on for longer time and I try to shutdown, the keyboard lights stay on and its still making sound, so it`s not really off. Moreover I need to press the on/off button for a few seconds, that it will be completely off.


Does anybody have the same problems or can help me?

T460p random freeze after BIOS 2.22 update / back on 2.20 everything OK

After BIOS update to 2.22 (released on 9th Feb 2018) i had random freezes on OS boot (using Ubuntu 16.04.3)


I could boot completely into OS one time but experienced a freeze there after a few minutes.

Most bootups froze when systemd was loading services but at a random point.


One time i could witness following message:

NMI watchdog: Watchdog detected hard LOCKUP on cpu 0

which repeated for all cores (0-8) in a random order and froze the system


I am now back on BIOS 2.20 and everything is working again.


EDIT: fyi i did load bios defaults after the update to 2.22 which did not help

Downgrade firmware Lenovo Tab 4 10 Plus

Hi everyone,


I have a Lenovo Tab 4 10.1 Plus, recently it has been upgraded to firmware TB-X704F_S000053_180122_ROW.


The problem is that now it shows a lot of messages like Error DNS and cannot connect to internet, even if it is connected to a wifi that works with another device (smartphone). The only way to make it work the WiFi is switching off/switching on the WiFi on the Lenovo Tab.


With the old firmware I didn’t had connection problems.


Any clue?


Tanks in advance.
