Anybody notice the keyboard ghosting on the Y500?

I've noticed in games that certain key combinations will cause one of the keys to fail to register. SHIFT and a punctuation mark seems to always make the punctuation mark fail but it obviously works outside of games, such as in a word processor for example. Additionally, holding SHIFT and then pressing 2 or 3 other keys might make SHIFT stop registering. Letters and punctuation marks mix fine though and I can press three or four of them simultaneously and have them all register so it looks like SHIFT combos are the most problematic. Anybody else come across similar ghosting issues on their Y400/Y500?

This isn't a huge deal for me but I just thought it was interesting because this is my first time experiencing keyboard ghosting. I've used countless laptop and desktop keyboards and have not seen until now.

 

The only time I've seen this happen is if there is physically something underneath the key (e.g. a crumb, a nail clipping, hair, etc). Typically, a hardware failure on the keyboard would cause the entire key (and possibly several other surrounding keys) to simply stop functioning.

Pop off the problematic key, and clean out the area below the key. That should do the trick.

 

No it's not the keys disfunctioning. They work perfectly fine when not gaming. You can look up ghosting but it's basically when you press a certain number or combination of keys simultaneously some of the keys will fail to register input. It happens on all keyboards to some degree but I've readily noticed it on my Y500 keyboard because it happens on some of the most common key combinations I use when gaming. It's not a huge deal but it's pretty inconvenient when I have to press some keys several times or let go of others before pressing certain keys so that everything registers.

Note this is not the keyboard typing by itself or entering wrong characters bug that apparently plagued early Y400/Y500 machines.

 

Ahhh, ok. I re-read your post in more detail.

What you're describing sounds like N-Key rollover. It's pretty normal to find that kind of phenomenon... although I don't ever recall seeing it in as few as a 2-key rollover as you described (Shift + punctuation)

Yeah that could be it. As far as I know there are many key blocking or ghosting types out there and the Y500 has one of them.
