The V200 is identical to the V100 in terms of laptop assembly. The only difference lies in the actual model of the part used, but the steps to assemble and disassemble are identical. If you take a look at the Hardware Maintenance Manual, you'll notice that the new ones are for both V100 and V200.

It would be great if the service videos could be posted for Lenovo 300 Y500 series (7761-37Q). Infact its a very sorry state of affairs that not even a single manual is available on the lenovo site for parts reference for this category/series.
