The MBP had been shut down and stored for 3 weeks. Plugged it in, walked away and when I came back hrs later the magsafe light was green. Powered up the MBP and when the screen was finally live I noticed that, although the MagSafe light was green, the battery showed 1% !? Charger and computer felt warm, light always green never yellow.
using a different receptacle didn't help. after 3 tries I noticed that both, computer and charger, stayed cool.

IF you try and check, test, and use all the steps in the Support article about
re-setting the System Management Controller, ahead of performing an actual
SMC re-set; do that exactingly. Each step. One of these may help and then
you'd not need to use the SMC reset because that by itself may not help.
A few days ago after going through to see the status of my older Apple products
here in a box (in cases, some in bags, inside the box) I got around to looking into
my original MacBook1.1 13-inch 1.83GHz first-edition coreduo portable and as
the battery would usually need a charge before startup (after sitting for ? months)
I thought to charge it up first. Before not-too-long, the charge indicator read Green
on the MagSafe power cable. So I was suspicious.
So I started up the MacBook1.1 and the desktop battery indicator showed 29%.
A few restarts and nothing changed. I re-studied the instructions ahead of SMC
re-set in that Support article to see what all I could do before the last possible
step, to fix this issue. Because I consider something might work, SMC may not.
Not sure now what item on the list of pre-SMC reset things to do before trying
the Final one, but I still had maybe two left to try. There was at least one or two
restarts involved, per exact instructions; and once the desktop came back up
I left the unit to try & charge. And so it did. I managed to get the battery charged.
See the part after list of 'indicators that the SMC might need to be reset'. ~ Go
to where the next section says 'Before you reset the SMC' & start by doing those.
Each of them, one by one.

While the battery may have another reason for not being able to get a charge or to
hold one, these steps did a surprising wonder. And because I'm certain the MagSafe
charger and its connections were likely OK and looked good, and the MagSafe DC-in
Board seemed to be able to route the power correctly, I sought another solution.
The battery nor charger in my vintage first-edition MacBook1.1 aren't new; and aren't
original to the computer. I did use the System Profiler (OS X 10.5.8 is in this model) to
see what the battery expectation was in possible total charge capacity vs what it told
me the battery had left. As these age, the total capacity changes, so it is possible for
a battery that says 100% to have much less than an original new total capacity.
There are Support articles on how to Troubleshoot MagSafe adapters, how to maintain
batteries, and other stuff. ~ I've posted them a few times online, each time by scratch
where I test the links in a browser before I re-post them... I'll not do that today, though.
Good luck & happy trails! 🙂
Hi,
Battery parentage can be wrong. Have you tried running on battery?
Look in System Information > Power > Battery and see what it says for battery cycles and health. You could need a new battery or a new power adapter.
Thanks for your detailed answer. I finally got the warning that the battery needs to be replaced NOW. Since I only have 470 cycles I decided to call the local Apple Store and was rerouted to an Apple tech. He pronounced the battery dead and the MacBook a vintage computer which cannot be serviced at the genius bar. I need to find an authorized service company to replace the battery. The Mac works as long as it is plugged in. Glorified desktop. I will check into the visability of a new battery since I hardly ever move the vintage laptop anymore. Vintage? I'm 72, does that make me antique or maybe even ancient? 😉
You could check this site and see which model battery appears when you
enter your MacBook Pro (display size - may matter) and they may have a
replacement battery there. The brand 'newertech' is a good reliable one
but may (or not) require you to calibrate it so the battery gauge reads OK.

This company has several items to replace or upgrade older Mac models.
And there are guides to use to replace other parts not as accessible as
the battery; such as drives and other stuff. See iFixit.com guides for Mac.
There are three series based on Display size, & more guides in each section.

The macsales OWC site has video guides (to view free) help in replacement
of various parts they also sell. ~ You need not buy anything to use info there
or if you have questions... Also note the tools you may need are listed in site.
This company is a reputable Apple vendor and offers good examples of stuff.
{You may choose to get a replacement battery so the portable Mac won't have
issue once you remove the failed battery; these can leak and damage the Mac.
And with the battery removed, the CPU (processor) may run at slower speed.}
Last year I finally had to buy a battery for my iBook G4 12-in mid-2005 model
through macsales of the newertech brand. First new battery since 2006 recall.
In any event...
Good luck & happy trails! 🙂
