Good point, and yes I did, but I found it less than adequate and
certainly not encouraging. Those drawings are hard to follow
For example, removal of the keyboard shows the rubber cover of the
ribbon cable connectors, but does not mention it's stuck on there;
and nothing about how to deal with that. The video guide was
reassuring, and showed it in a way I could see it better.
Furthermore, I found the instructions for keyboard bezel removal to
be removing too much. Lenovo said to remove the wireless LAN card,
the WAN card, the memory, the coin-cell battery, and the fan. I
didn't need to do those. And the keyboard did not need to be
disconnected; I could have saved a half hour of grief and removed the
bezel assembly around the still-connected keyboard.
Sadly, that's the kind of documentation manufacturers of all kinds of
things offer. More important than engineers' review is the lawyers'
review, and in many cases IME the lawyers add false and misleading
information in the interest of protecting the company from possible
As free software users we have had to learn to take authoritative
statements from hardware manufacturers with some skepticism. How
many times have you read, "This device only works in Windows," and
found that to be completely false?
That said, I concede your point about the value of consulting
Lenovo's maintenance manual.
