3-key-combination not working

0

I'm having this weird issue with my laptop. I can not use some of the 3 key combinations for some reason. I can use some off them, for instance, CTRL+Shift+T to re open closed tabs in chrome, but at the same time, I can not use CTRL+Shift+Left_Arrow to select previous word(s) while programming. This is really getting on my nerves, I think this may be a hardware issue but I am too afraid to confirm it myself.

If someone can tell me a way to confirm whether this is hardware issue or some problem with windows, I'll appreciate it.

My laptop;

  • Haier Y11C
  • Intel Core m3 7th gen (1 GHz, 4 cores, 1.6 GHz with boost)
  • 8GB of RAM
  • 1TB of hard drive
  • 4GB of Intel HD Graphics 615

My OS;

  • Windows 10 Pro Education 64-bit (Build 17134)

Tried using an external keyboard? You might have some weird bindings. – spikey_richie – 2018-10-02T15:17:40.063

@spikey_richie yeah i tried that, external keyboard works fine. – user3762712 – 2018-10-02T15:27:44.500

Are any of the keys involved in the non-working combinations dual use (e.g. Have a different function printed on the key, usually in a different color)? – I say Reinstate Monica – 2018-10-02T16:02:48.420

No @TwistyImpersonator, there are no dual uses on these keys. – user3762712 – 2018-10-03T17:03:58.060
