Windows 10 "Left Alt + Shift" language input switch suddenly stop working. It used to work before.

Hi Jida,

There are a few reasons why "Left Alt + Shift" is suddenly stopped working on your computer. Since you mentioned that you already tried some troubleshooting steps, we suggest that you create a
Test Profile. From there, check if the issue occurs.

To create a user profile, follow these steps:

• Go to Settings. Click Accounts.
• Select Family & other people.
• Select the Add someone else to this PC tab.
• Name the user as Test.
• Leave the password field blank.
• Hit Next.
• Sign in as Test user.

Let us know how it works.

 

Keyboard Issues, LEFT SHIFT + LEFT CTRL + L/R ARROW doesn't work on travelmate P645-S windows10

LEFT SHIFT + LEFT CTRL + LEFT ARROW

LEFT SHIFT + LEFT CTRL + RIGHT ARROW

LEFT SHIFT + LEFT CTRL + UP ARROW

LEFT SHIFT + LEFT CTRL + DOWN ARROW

RIGHT SHIFT + RIGHT CTRL + RIGHT ARROW

List of combinations (Working) :

Please let me know why this issue is occurring!

Is this a hardware issue/ software issue?

i have updated keyboard drivers, also uninstalled and restarted laptop & let drivers install automatically.

Also i have checked if laptop's keyboard is loose or anything... everything is fine on that side.

P.S.

Recently i have upgraded my 4+4 GB RAM to 4+8 GB RAM

this RAM is DDR3 and may not be original

 

Windows + Shift + right doesn't shift window to the right screen (shifting to the left works fine)

When I use Windows Key + Shift + left the active window jumps to the monitor on the left like expected
But when I try to do it the other way around: Windows Key + Shift + right the window doesn't jump back to the right Nothing happens. Why? How can I fix this?

PS: I am using Windows 10 Version 1903 (64 bit) on my ThinkPad with two additional external monitors.
Windows Key + right moves the window correctly to the right (step by step but not directly to the next monitor).
Maybe the Windows Key + Shift + right was overwritten by something else? How can I find out?
