Asus Zenbook UX21E - US model

G'day guys/girls,

I have an Asus UX21E Zenbook that has a issue with some keys not working. At all times the various keys - O,R,U,W,Y and Enter - do NOT work!!

This is true regardless of OS, because when I go into the BIOS it still doesn't work.

What I've tried:

- Updating the BIOS
- Resetting BIOS back to factory
- Re-seating the ribbon cable that connects to the mainboard
- Wiggling the ribbon cable while on to see if its a poor connection - NO DIFFERENCE
- Updating drivers, changing OS, trying various fixes supplied on the internet.

What I'm about to do is purchase another keyboard if that might fix the problem, but the laptop is 2 years old and I don't want to spend more than $100 if its not going to fix the issue.

Anyway just thought one of you wizzes out there would know what to do, so I leave the ball in your court. Any help is appreciated.

Regards,
Steve

Yes, looks like your keyboard is defective.

BUT. Unless you take it to a repair shop to confirm the problem (by physically connecting another KB and verifying that it works) no one online is going to be able to tell you 100% sure that a new KB will work.

That being said, a new keyboard will net about $40, so it's not that expensive if you really don't want to have your laptop checked at a repair shop.

HTH,
Dan

Thanks for the response Dan,

Unfortunately (in this regard) I live in Australia which means that all normal prices are hiked up by 3x which means the cheapest I can get it for is $100.

That being said I have purchased the keyboard, because I don't know what else could be the problem.

I will post back next week when I receive the replacement.

Hopefully its not going to be too hard to install :)

Actually, the KB is one of the easiest things to replace... after you get to it :)
Most laptops have plenty of screws to remove and some tight plastic couplings to pry apart (for which I use a plastic pick), before you can remove the KB and pop in a new one.

Good luck with your new keyboard.

What you could try before getting the new keyboard, is to attache an USB external keyboard. If those keys don't work either on that keyboard, then it is a problem with your keyboard controller on the mainboard, and not with the keyboard. That would also mean that a repair would get too expensive, as you'd have to replace the mainboard.

Thanks Rindi,

I have tried connecting a USB keyboard and it worked flawlessly, although it was a wireless one, so it might not be the same.

Wireless or not, that doesn't matter.
