Originally, I had a customer bring in a laptop that had some liquid spilled on it. No big deal, the keyboard was faulty afterwords, and i have replaced it. The good news, almost everything works as it should. Except the battery doesnt seem to be charging.

I am certain that the magsafe port is functional, as the unit does power on when plugged in. The battery itself still has 24% from when it was charging. I just want to hear any other advice before I go ahead and order a battery.

Thank in advance.

If the battery isn't charging, and this is definitely something that JUST started happening, then the problem probably isn't the batter. Especially with spilling involved. The customer won't be happy when the new battery doesn't charge either.

Did you test to see if it's even attempting to charge? also if the battery is outputting any current... multimeters are your friend!

The battery still outputs when disconnected from AC. The magsafe adapter light does not light up.

There is no way to know if it just started happening. The kid brought it to me months after it stopped working. I am impressed I was able to restore it to this point, to be honest.

I wonder if the Mobo's charging circuitry is damaged. As a client, I'd be pissed if you ordered a battery, got it and it still didn't charge due to misdiagnosis, then had to wait longer for a mobo replacement. Now, I am not saying that you misdiagnosed anything... but I wouldn't be 100% sure it's the battery. Based on what I've read, it isn't. I could be wrong, but I'd just like to see you avoid making a mistake that would cost you a client and $$$.

Im not worried about angering the client right now, just rectifying the problem. Been doing some reading, and poking around, and I am wondering if it is possible if it is the magsafe adapter itself. While I did have to disassemble this unit a few times, I did test it several times to make sure the overall properties didnt change, and I seem to remember the green light coming on on the adapter. On other laptops, I have seen issues where the adapter will power the computer, but was compromised enough to keep from charging the battery.

Your last post, is exactly what I am talking about. Diagnose twice, order once. lol

Is there voltage at the prongs that go into the battery?

Easiest way to rule out the adpater is to test with a known good one. Liquid spills can cause all sorts of spooky weirdness, I'd also check the magsafe board if I were you. You didn't say which machine it was... Try a good adapter first. If that doesn't help, try the good adapter with a known good magsafe board.

It all boils down to paying attention when reassembling a unit. Turns out a little wire from the MagSafe board got caught by a screw and caused it to groundout against the casing. I repaired the break temporarily until a replacement arrives and it works fine. Thanks for the sounding board. Working alone makes it harder to bounce ideas off of empty walls.
