laptop keyboard issue

[orze]

so i got a preety cool laptop not too long ago its old but it was free from family so u dont say no to that

its a lenovo yoga  500 s14 i bellive

 

its decent and i like it but it has a major issue

if i press "r" it will type "r5"  same as if ill just press 5 it will write the same thing

 

same thing is with "i" if i press it it will write "i=" i tried installing drivers for it thinking maybe its a keyboard software issue but nope.

it wasent used for a long time and my family member didnt use it allot so he dosent know why could do it.

could that be a hardware issue? but in that case how does = is pressed all the way from "i""???

 

this is really confusing as i need to use a outside key board to type and if lets say i will press and hold "R" i will just get this:

r5555555555555555555555555555555555555555555555555555555555555555555555555555555555

 

thats from holding R......really wierd. anyways thx to any helpers.

Some of the legion 520 and maybe even 720 gaming laptops from lenovo had a similar problem one or two years back (and might still have them). It was basically caused by bad manufacturing. So I would suppose it is not too far fetched to assume that yours, even though it's a different lineup, could suffer from the same or an equal illness.

I don't recall the exact cause and couldn't find the topics after a quick google search either but it was something along the lines of a keyboard cable or the keyboard itself getting in contact with other components inside the device or simply the metal housing of the laptop and hence got interrupted signals which caused incorrectly registered keystrokes.

 

For these the fix was an utterly epic-fail one by either taping the cables or adding some sort of “buffer” or electrical isolators between the affected areas of the device.

So if you can be bothered, just open the device up and check for similar possible causes.

 

 

Though even if it's not the above stated cause, if an external keyboard works you are most likely looking at a defective keyboard or even motherboard on the device itself.
A windows factory reset cant hurt, especially if it's win 10, but personally I don't see any chance of succsess in it.

well its worth a try ill try dis assembeling the thing wan im home and doing that

its a fresh install of windows so id guess thats not it sadly. and well will see soon i guess

thx tho i truly hope me repluging the eyboard and adding is gafa tape to its back will help XD

if not i might just look online for a repllacment keyboard. its allready a free laptop so costing me even 20$ isnt allot if i fix it.

 

thx anyhow!

hi so a update i indeed opened it up and it seem the keyboard got a big metal cover behind it and im not sure what to isolate really.

To be honest I’ve never opened up a lenovo device and neither did a keyboard replacement or removal.

So I don't know how much of help I can be, but if you post some pictures of the opend up device I could at least try.

If you made sure that the keyboard cable is plugged in properly and was “laid out” in a way it could not possible be run into any kind of interference than yes, maybe it's just broken.

 

You could try to remove the keycaps form the keyboard and see if they might be faulty, dirty or similar but that's highly unlikely to be the cause IMO. 

 

We actually had a laptop at work, from HP, which had a similar problem that after being repaired for liquid damage the keyboard did not take a few keystrokes at all anymore, like winkey, K, D and such while everything else was fine.
After another Keyboard replacement, same issue. After a motherboard replacement with the same keyboard, problem solved.

So out of my experience it could be both,  though 20$ for a possible fix, does not sound like a bad shot to me.
