w500 keyboard super-loose-noisy!!

2008-09-11, 3:07 AM
Anyone else out there have trouble with a rather large air-gap under the left side of the keyboard causing it to sink and make a TON OF NOISE when typing; not to mention mushy, etc... the right side is fine... I just got my x500 yesterday and I am tempted to send it back to to the poor keyboard mounting (underneath). Or is this a real defect in the design of the darn thing.

Hello,

 

do you really have a X500?? I know only model numbers X200/X3007X301 of x-series.

 

Or is it anything like T/R/W500? Please, look at your display bezel.

The see this article on Lenovo blog.

 

Kind reagards

Andreas

oops.. I meant a w500. In fact now that I look at the bezel closely; the leftt side is much wider than the right side; looks like the display is off-center as well... Man, this is strange... But biggest problem is the darn keyboard flopping around on the left...

Hello,

 

you can try to reseat by yourself look here on Lenovo Training.com .

There videos how to open palmrest and keyboard it´s the same procedure like T-Series i think.

Loosing just 4 srews.

 

There is a diskussion about this incident on Lenovo Blogs.

An altnertative may be to buy a T60/T6 keyboard, they are more stiffer.

 

Regards

 Andreas

I haven't had the chance to see one yet but I bet with the proper tweaking the keyboard would lay flat. Still it should not be like that from the factory.

Re: w500 keyboard super-loose-noisy!!

Guys.. did a bit more research into this and compared it to a T61 which is the same form-factor/case/size/etc... The T61 keyboard is MUCH stiffer and is basically "solid" in the back. The W500 keyboard-plate is full of air-holes (possibly to allow more airflow from the processor/drives...) but that results in a super-lame keyboard experience (mushy, sinks down on the left side, etc...). there needs to be either some support on the left side or a more rigid back-plate to the keyboard. Can anyone from Lenovo recommend something? I have my laptop all configured nicely now, and would rather not return it and get something else, but there is no way I will use this thing the way it is.. .The noise alone will give someone a massive headache and annoy anyone within 20 ft. Or maybe I could try only using the right side of the keyboard instead! :) LENNOVO?

The problem is that there is a real air-gap under the left side. It doesn't really have anything to sit on underneath. I guess one could glue something down there, but it is close to where the heat is pretty heavy..

Agotthelf, It is clearly not a seating problem but a design problem. The T60 keyboard are much better and would clearly work, but I am certain that the Lenovo folks considered that already and didn't do it for a reason... like heat? If so, replacing that keyboard with a T60 one would probably cause big problems down the road.... I am very close to sending this thing back. I honestly can't believe anyone in their right mind would ship a laptop with this type of keyboard situation. It is the only thing that a human has to TOUCH repeatedly (especially the A and S keys).

They didn't design the keyboard with holes due to heat reasons.  The notebook has a cooling system with a fan for heat, Lenovo has never historically relied on the keyboard to cool.

 

It's simply a matter of supplier.  Historically there have been three providers of keyboards on the T-series notebooks.  I believe NMB, Alps, and Chicony.  IIRC Alps are made in China, and the NMB keyboards (at least in the T4x days) were produced in Thailand.Chicony may also be Chinese but I'm not sure.

 

Most Thinkpad users seem to agree that the NMB keyboards feel the best.  The KB that seems to be shipping on most of the W500s is NOT an NMB.  Historically, you can tell an NMB by looking at this Image - the keyboard on the bottom with the blue membrane switches is an NMB. I happened to get lucky when I got my T6x and came up with an NMB first try, so I just swapped it to my W500.  With the T6x the suppliers may be different, but the keyboard that I happen to have feels exactly like the NMB I had on my T42p so I've been calling it an NMB.  ;)

 

The T6x keyboards are a direct fit on the W500 and work fine.  It is true that there is a bit of an airgap on the left side with the W500, the NMB handles this better as the back is a solid piece of metal (albeit fairly thin).

 

For more info, check out this thread on the unofficial Thinkpads.com forums. The parts referenced are for T4x notebooks so I don't think they'll fit on a W500, but the T6x series of parts definitely do work.  I don't know if anyone has gone to the effort to figure out who the suppliers are now and which spare part number comes from what OEM though...

thanks for adding this good detail... I checked mine is clearly a made in CHINA type. Part number was 42T3904 ; model MV89.... I didn't see it on any of the links provided here... I will hunt around some more. In the meantime, CDW is going to ship me another laptop in the hopes it will have something different/better in it for the keyboard.
