Keys gone haywire on laptop

I have a Samsung R60 laptop. All of a sudden, some of the keys have started misbehaving. Some will not work at all, do not register, others produce a totally different character or symbol to that presses. Others work properly. I have done nothing to change anything. Can I assume that the keyboard pcb is now useless and this sort of fault cannot be rectified without somehow taking the keyboard out and tinkering with it. Am using an external usb keyboard to get round the problem.

Sounds like the keyboard circuitry has gone. If under warranty I suggest you contact the retailer. I am assuming there has been no liquid spill involved here but that is the most common reason for a keyboard to react like this.

Either way the keyboard should be replaced to determine if that's the fault - absolutely no point in "tinkering" with it. New keyboard should be about £20 I would think and probably quite easy to replace yourself. (Would need to check for you.)

Have you tried re-setting the language and region to English UK? It may make a difference although if the external keyboard is working OK it does sound like a bad keyboard connection. No fluids spilt on it or anything like that?

If external works OK, then problem is keyboard itself or may be the ribbon cable that connects it to the mobo. I have had problems with sammy lcd cables where, reseating them had cured the problem. If not, keyboards aren't expensive and are simple to change (if you have a bit of knowhow). I don't have a manual for your model, but it's possible the R50 may be similar here

Thank you all for your quick responses. You confirm my feelings. Not sure about my ability to tinker with keyboard, but may get it repaired at a cost, although as external keys work OK, will persevere for the time being. Thanks,

This may be a stupid question but have you made sure that num lock isn't on?

Yes to both questions !

If you look at the video, you'll see it's a five minute job to change the keyboard, so nothing to be concerned about!
