# Two guides, same laptop, different authors

Hi iFixit admins,

I have an unusual question.

I found two device pages that seems to be different but are the same :

I don’t know exactly what I should do in this specific case, so here is the details of the problem :

On these two device pages we can see, they seem to refer to two different model numbers, “PCG-7A2L“ and “VGRFS640“.

In fact, the “PCG-7A2L“ is not a model number used to target a specific laptop model, it’s more like a chassis model, the PCG reference number should not be used as an identifying number, since it describes a group of similar products and not a specific model.

And “GV**R**FS640“ is not a valid model number, in fact, the true model number for this laptop is “VG**N-**FS640“.

If we observe the two device page images in full size, we can read the real laptop model number that is “VG**N-**FS640“ link to the images :

Here is the zoom of the model number labeled on these two devices :

For the device page “Sony VAIO PCG-7A2L”, we can read on the device label the model is in fact a VGN-FS640 :

For the device page “Vaio FS series VGRFS640”, we can also read on the device label the model is in fact a VGN-FS640 :

If we look closely at these pictures, these devices are in fact the same and the given model for both of these device pages are both erroneous and there real model is in fact “VGN-FS640“

Also, the two device pages contains different links to the Sony e-support, one refers to the “VGN-FS640“ and the other one refers to the “VGN-FS645P“ but one of them (the VGN-FS645P) does not correspond to any of these two guides as in the Sony Specification Sheet of these two models we can see at the laptop appearance the two device pages cannot be a Vaio VGN-FS645P :

**Here is a potential solution to solve the problem** :

As these two device pages doesn’t refer to the correct laptop model but contains correct teardown guides for the device (Vaio VGN-FS640), I suggest merging the two devices page in the same device page with the real laptop model, the Vaio VGN-FS640 . So we can keep all the teardown guides associated with the correct laptop model number.

Is this a good solution ?

Do you have a procedure when two device pages must be merged into one ? (as it seems not to be a common use case)

Thanks for reading :)

Is this a good question?

Hi @es_six, this is an interesting case. I'll look into it next week and work out a solution. Thanks for pointing it out!
