left shift key disable my number 5 key

so i tried using my sister's laptop(sony vaio) then i noticed that my left shift key disable the fuction of my number 5 key...i noticed it when i was trying to type % sign. So in order to type % sign you need to hold shift and press 5 key...but whenever i hold down my left shift it disables my 5 key, whats weird is it only disable the 5 key it works normal with the other key and my right shift works perfectly...only the left shift and 5 key is the problem...do u guys have any idea how to fix this?

Hi,

Does it register that you are pressing shift and then 5?

it doesnt...now i can really confirm that it actually disables it...the 5 key doesnt turn green when left shift is hold

butit does turn green when i used the right shft


what do u think i should do?

I've never encountered something like that. You're using a laptop, hm?
Do you use drivers for the keyboard?

Check like so:

Search for "device manager"



In the device manager find the tab Keyboard


Rightclick it and select properties.

Next open the Driver tab like here and check where the driver is from. You can also try to "Update Driver" and see if that helps.

its fixed now...but im not sure whatfixed it ...i tried to update the driver but it said its already updated and i also click thescan for hardware changes...not sure which of those two fixed it....thnx for the help
