As stated earlier, the lookup by serial number and other databases available
to me suggest your product can be identified with the number A1261; but I
was trying to more exactly identify it. By using the Build Month/Year info from
powerbookmedic lookup, your product is closely identified (where it co-relates)
where all these bits match. I looked up Serial Number (system): W8xxxxxR8
you supplied, with those numbers not xxxx'd out.
Both 17" products use same A1261 number, but are 2 distinct different builds.
Yet the main 'build date' clearly appears to place your unit as newest of two.
And according to MacTracker database, it is the newer of the two. Go with it
for the rest of the information; there is a question of the EMC number; only
one (early) uses that. Use database at http://everymac.com to further affirm it.
"Based on the Build Yr and Week info from powerbookmedic database
I'd say your MacBook Pro4.1 17-inch model would be Late 2008 build."
So with this, you should be able to tell the parts reseller what you think it is,
and why. Other sellers of parts may be able to use the serial number from your
product to narrow down the correct replacement parts for the one you have.
{Within the MacTracker app, I can look through in progression, and see all of
the model build series numbers along with specifications; but your model has
two appear with same A- number. This number is not the problem, as I see it}
Seems to me the main issue would be to affirm the hinge parts either are the
same - between these to model builds - or if not, to get the parts that fit.
Some of the parts suppliers can be talked to by phone, for example if you are
able to call wegenermedia in the US during local business hours, and ask if
they can quote you price and availability of replacement hinges for a 17-inch
MacBook Pro (A1261) and then say, you understand there are two models
that use this same number; by serial number lookup (powerbookmedic) they
say yours is a Late 2008 with sales order number MB766LL/A made in Oct
2008. If there is a difference between those hinge parts, & -other- Early 2008
model that uses sales order number MB166LL/A (EMC 2199) that uses same
other number, A1261, they should be able to tell you from their database.
Only one of these (early) shows an EMC 2199; while both show A1261.
At this point, be sure: if you do order parts with an idea of someone else doing
the repair work - who has agreed to install parts you supply - the parts are correct.
Be sure to ask - if a return authorization is required - should the parts not fit.
There is a high likelihood the Early 2008 and the Late 2008 MacBook/Pro 17-inch
both use the same hinge; if there was an upgrade those specs, later should have it.
Your original Sales order number may help the final confirmation.
Good luck and happy trails! 🙂
