I was testing a Thinkpad SL500 system at a local store and found the flexing of the
LENOVO Thinkpad R61 Keyboard to be quite a deal breaker for me; it was flexing quite prominently with very little pressure applied. I find it hard to believe that a business grade laptop should have this problem as a consumer grade laptop that I own (Dell Inspiron 1526) has very little keyboard flex and one needs to apply a lot of pressure to notice it.
Is this a common issue with the SL500 or SL510 models of Thinkpad laptops? What about the Thinkpad R500, does this also suffer from similar
LENOVO Thinkpad R61 Keyboard issues?
There was a problem with one specific
LENOVO Thinkpad R61 Keyboard series in some of the T400s and 500s that did this; Lenovo will swap it if you call and complain. I do not believe any of these ever made it into the SL500 though, and am also unaware of any complaints about the keyboard. (And I used to do first level tech support for Lenovo!)
