T420s Keyboard Flex

Upon receiving my T420s I immediately noticed that there was some pretty serious keyboard flex on the lower right corner.  Just recently I sent it in to Lenovo for repair in  an attempt to fix this and other various cosmetic issues.

 

This is a video I took after I got my laptop back from the depot....they actually replaced the keyboard but this obviously didn't fix the core issue at all...I really didn't appreciate the stupid stickers they left around with the case number on my adapter and optical drive either...

Needless to say this hasn't been the most pleasant purchase experience for me - I've been plagued by various little defects such as the fan noise issue and various little creaky spots on the laptop which weren't really fixed at all when I sent it in to the repair depot.

 

Does anyone else see any flex on the lower right portion of their T420s keyboard as well or am I just terribly unlucky?

I know that some duct tape / felt behind the keyboard could probably fix this but I would prefer it if Lenovo would have this all working perfectly so that don't have to resort to taping stuff up.

No serious flex for me.

Re: T420s Keyboard Flex

Any suggestions on how I might go about getting Lenovo to fix this for me?  I tried their report depot and all that happened there was me going computer-less for about two weeks with absolutely nothing fixed in the end.

 

I see a little "Repeat Team" phone number on a sheet of paper that I received along with my system back from the depot but I have a feeling that the exact same thing would happen if I send it there again...perhaps getting a solid-backed keyboard would remedy this issue as well but I don't know if there is one that works on the T420s.

Maybe your chassis is just warped? Try standing a 30cm ruler across the chassis.

Re: T420s Keyboard Flex

Hah I don't even need a ruler to see that the internal magnesium framing right over the UltraBay is not straight in any way whatsoever.  The question is what am I going to do about it....it's already been at the Lenovo service depot for about 2 weeks and they said oh nothing's wrong with it....

Re: T420s Keyboard Flex

Pretty sure the enlarged Esc/Del keyboards have no solid-backed variant. Not sure if it'd totally fix the issue in such a case. A shim solution is probably your best bet.

Re: T420s Keyboard Flex

Bleh...I'll probably try complaining to tech support for a while longer and eventually end up breaking out the duct tape...

I'm pretty sure just putting some duct tape for padding behind the keyboard in flexy spots will do the trick but I never really like doing these patch-up jobs to things that should be working in the first place.

 

I'm going to eventually have to resell this system in a couple of years and I'm afraid that when doing so I'm going to have to explain to people how there were flexy spots here and there and tell them not to worry because duct tape fixes everything!

Heh. Use black duct tape and pass it off as being naturally there along with the other black sheets covering the system components. Smiley Wink

Re: T420s Keyboard Flex

I had exactly the same problem.

I fixed mine by removing the keyboard and layering around ten layers of sticky tape vertically to the underside of the rightward side of the keyboard.

 

I feel a little annoyed at Lenovo for having to do this to what is supposed to be a premium quality laptop.

This seems to be an intrinsic design fault with the T420s as I have a spare T400 keyboard to compare it with.

That keyboard has 4 screw holes; one in particular is mounted close to the area that was flexing on the T420s.

The T420s keyboard however, is held in place by only two screws.

This really is ridiculous.

In my day job, I service HP laptops, and although I've never seen so many faulty laptops pass through my hands in my life, at least they are well screwed together.

Come on Lenovo, for the sake of fractions of a cent/penny to put back the screw mounting holes which were removed for this model, you can do a lot better than this.

Especially at this price point.

Lenovo, are you listening?

A T400 keyboard only has one screw...
