Q: which adapter for 2009 MBP (MD565LL/A)

The original MagSafe adapters (depending on model/year shipped with) could be

either T shape or L shape; some could be interchanged. The official advice was to

try & get identical replacement. - note: newer MagSafe2 had similar appearance

while not interchangeable both directions... this may be confusing in details.

MagSafe 60w and 85w adapters could be used on your computer; if it shipped

with the 60w, that would be OK to use an 85w if it's otherwise compatible.

Other Magsafe 60W for all MacBook, MacBook Pro 13 Item(s) owc macsales

Sometimes, OWC macsales.com has a selection of various MagSafe Apple

power adapters & some batteries. The low power 45W MagSafe adapter for

the MacBook/Air should not be used on a higher demand other model MacBook.

Your MacBook Pro is an older model, be sure to note the model could use

either type of magnetic end. I have an early MacBook that serves to confuse

because a generic clone of questionable source, was given to me, with it.

And quality is the only real issue to me. The generic has no Apple logo and

probably has inferior parts inside that may fail or get hot, and so on.

For non-Retina models this covers most 60w models

Is your MB/Pro a 13-in or a 17-inch model?

The model identifier of Mac can help when available.

The need to identify the computer helps if you are looking for

parts replacement or to discuss services, repairs, etc; and over

a distance where you may not be able to carry in the unit...

• How to identify MacBook Pro models - Apple Support

According to MacTracker specification database:

if your computer is:

If your computer does not have the Retina display, and is not 17-inch the

60w adapter should work; note in the suppliers web page, the magsafe in

macsales listed item http://eshop.macsales.com/item/Apple/MC461LLARB/

does show what models it can be used with, and identifies them there.

So the earlier MacBook and Pro models that are listed can use that part.

Larger screen models may have shipped with the 85W MagSafe adapter;

it would be backward compatible to 60W if same connectors are on both.

See the posted link to "Find right power adapter.." for general matchup info.

My 13-inch MacBook1.1 (not pro) is using an 85W magsafe. It probably

is the early MagSafe, not the later Magsafe2; and has T connector. Yet

the L connector was available during the production years in like form.

New replacements most likely have the L shape; a few may be T.

While it is possible to use an online Serial Number Lookup service, not all

of them are secure. This one uses an https:// or a secure site prefix...

• Mac Serial Number info - Lookup your Apple Serial Number:

https://www.powerbookmedic.com/identify-mac-serial.php

For your personal information, if you haven't found details the Lookup will

provide (build month, day, year, hardware specifications as shipped, + other)

from the computer, need not be posted here. Serial numbers and other detail

of that nature can be avoided; + usually are removed from posts by the host.

A good source of additional specification information is available from the

download application MacTracker from http://mactracker.ca & it is free.

An example of a 13-inch MacBook, listing from MacTracker (there are 5

different models listed for the 2009 build year series) would provide the

inquiring mind detailed information; such as Model Identifier...

And to get the correct replacement or upgrade parts, RAM, HDD, etc

this information and identification is very helpful. Or just the serial number

if you deal directly with Apple Store genius or an Apple authorized service

provider who has greater access within the Apple database itself. I don't.

Hopefully the part should be easier to find; if not from macsales, there are

a few possibilities once you identify the computer correctly, online via sites

such as amazon who have sellers. Some computer stores may also have

the correct part, but be wary of cheap clones or looks-alike/not Apple parts.

Also, a good resource may be to look into the MacBook Pro Repair guides

- iFixit.com: https://www.ifixit.com/Device/MacBook_Pro

and with correct MacBook Pro build model identification you can use the

proper guide to see how to upgrade or inspect (clean dust?) Or just see a

few nice images of the inside of the portable -- without having to open it.

Good luck & happy computing!

The product linked to where the image (macsales) appears to be a correct part

and that one has the L-shape connector. The OWC macsales.com site is helpful

as a reference; they also have good DIY videos for replacement of drives, etc.

This 85W would also be a valid choice & should also work based on site info

for models that meet the general specs of these MacBook Pro models that

do Not have a Retina display, within 2006 to 2011, and some 2012 builds...
