Windows 10: Keyboard Issues, LEFT SHIFT + LEFT CTRL + L/R ARROW doesn't work on travelmate P645-S windows10

Recently i am facing issues with my laptop. Key combinations doesn't work especially with SHIFT.
List of combinations (Not working) :
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) :
RIGHT SHIFT + RIGHT CTRL + RIGHT ARROW
CTRL + C, CTRL + V, CTRL + X
Other than above 'working' combinations no other combination works with CTRL and SHIFT
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

Control Left Arrow doesn't work - Windows 10

I will assume you don't have any keyboard mapping tools?

I suggest you try AutoHotKey and map that combination to something else, like opening Task Manager. This will then prove if the issue is the combination of the 2 keys being pressed/sent, or the program where you're using this not accepting it always (for unknown reasons).

Test this new combination with no programs open from the desktop to make sure it works every time.

If it does work each time, open the program where this issue occurs again verify if this combination works every time (if it opens Task Scheduler).

If it does, map CTRL + Left Arrow to itself (eg, map CTRL + LEFT ARROW to CTRL + LEFT ARROW) to see if that has any affect.

 

Left CTRL key only works together with the left SHIFT key

Hello,

Starting from today while I was using FL Studio to copy some musical notes I noticed Ctrl+C and Ctrl+V weren't working

I've opened the on-screen keyboard in order to check if the left CTRL key was working and pressing it alone doesn't show any input.

But. when I tried to first press the left SHIFT key holding it and then pressing the left CTRL key together. both keys showed input. (right CTRL key works fine)

Is there anything I can do to fix this issue?

I've already tried to uninstall the keyboard's driver and then restarting the PC but it didn't work.

Best regards,

Me

 

WIN+SHIFT+L/R ARROW Doesn't work, any alternate?

Hi Sean, welcome to the Ten Forums.

I have build 9860, works like a charm. All I can suggest is that you upgrade as soon as possible.
