Can someone with a service manual give me some test points and

I strongly doubt there is one - Apple services these machines at the
subassembly level. Suggest you do a comparative, since you have a
second machine available.

Also, I have encountered odd charging issues where the machine was
otherwise working OK when the MagSafe contacts were dirty. Make sure
you clean those too!


Thanks for your post.

The other machine is not mine so I can't really disassemble it.
Just tried re-cleaning the contacts, didn't help.

Sometimes removing the battery and powering up from the charger works
to reset something. I haven't a clue why but its worked a couple of
times for me on a Dell and a HP machine. HTH.

Thanks. didn't help

Sorry about that !
Just a guess... Could there be a magnetically operated switch behind the
connector.
