I replaced a water-damaged Macbook (mid-2008) logic board and it now works, however it doesn't work properly when the battery is plugged in.

I figured it just needed a new battery but even the brand new battery does not charge in the Macbook nor does the Macbook function properly with it plugged in.

Remember the Macbook works fine off the wall charger with no battery installed.

What component still needs to be replaced to get this to work?

I have run trouble shooting programs from Apple website, but this does not correct the problem.

Apple suggested I take it to a repair shop.

Anybody have an answer to this?

Also, this is probably something else but, the nano seems to shutdown after being unplugged.

I would be happy to know if it can still be salvaged or not.

so, my ipod hasn't been holding a proper charge for a while, and being a few years old, i decided to just replace the battery.

new battery came today. i replaced it, plugged it in, won't turn on at all now. i've checked the cable connections three times, held menu + center button for a minute just to be sure, nothing. won't turn on, no hard drive noises, nothing.

i tested the integrity of the connections by reinstalling the old battery, and it turned on when plugged in.

what to be done? did i get the wrong battery? ( http://www.ifixit.com/iPod-Parts/iPod-Vi... this one) it is defective?

Its battery zeroes at 3 hrs.

What's the "normal" power duration for a device like this?

Does its battery need replacement?

I read so much about the difficulties of desoldering and soldering on the iPhone board, thought this might be a safer route. Of course, you still need to be careful not to cause a short, etc.

this is what happened. I had one of those mobile battery that you just plug to the power slot of Iphone and it will charge your Iphone right away.

However silly me ;(, I charge this battery for the first time like this:

wall charger connected to (Iphone with this mobile battery plugged).

It initially won't charge at all.

Now some strange issues I had are:

1. My phone will charge just fine and the brightness is just fine IF it is connected and charged to my laptop. Otherwise, the screen will completely dim and it's almost unviewable

2. It will just charge for a while with the wall charger BUT black out after I left it for a while

any solution to this problem?

Is my screen fried ?

is my battery fried?

or what?

thanks before

I have a macbook mid 2007 that shuts down immediately after it is unplugged from AC. I've tried the battery on another machine and it works fine as well as trying a known good battery in this machine.Also I've tried a known good AC adapter. Other things I have done are run the hardware test which shows no errors, reset the smc and Pram, repaired permissions etc. the battery appears normal in the menu bar and says it is fully charged.Also it Appears in system information as normal.coconut battery also appears normal with 275 cycles.I'm hoping the problem lies in the Battery Connector with Sleep Switch and not the logic board. Anyone had any experience with this problem?

One other strange thing is that after unplugging the AC the system shuts down immediately, but once you plug it back in it starts without the power button being pressed.

My MBP shuts down after a few minutes if it is not plugged in, so I think my battery is defective.

But if I plug it in and let it charge for a while and it is nearly fully charged then it switches between charging and not charging and the LED on the MagSafe is switching (green - orange) too.

Is this the power adapter or the Left I/O Board or is this the battery too?

If I take out the battery it is still running.

Can I check the parts somehow?

This actually isn't a huge problem-- I'm pretty diligent about watching it and getting plugged in before I hit 28%. BUT it would sure be great to get a low battery warning when I hit 38%.

(The ideal solution would actually be to reprogram the battery to think its capacity is accurate, but I don't think that's feasible without accessing its internal electronics.)

I have tried with another AC adapter but still same problem.

No problem when the iBook is working with battery.

How do I know if the problem is in the DC-in board or in the logic board?

thanks

Update

I tried all your recommendations (reset PMU,PRAM, removed the memory module and another AC adapter) but no success.

I suppose it is not a DC-in board problem because if I disconnect it from the logic board there´s no beep. I think the beep sound comes from the processor area, is that possible? is there some kind of speaker on the logic board???

is very strange because the iBook works well with the battery, so I assume that the processor is not dead.

Update 2

I have replaced the DC-in board,

the long beep is still there.

No success. :(

Update 3

-"What country are you in and what is the standard outlet power?"

Spain (Europe), 220 Volts, 50Hz.

-"Are you using a battery backup?"

I use 2 batteries, one from the iBook G3 and one from an iBook G4.

-"Describe the tone better. how long does it last? Have you ever heard the tone a battery back up power supply makes when overloaded? Does it sound like that?"

2 links for hear the beep:

http://www.megaupload.com/?d=RESISETC

http://www.sendspace.com/file/jtaezg

the beep sounds untill the adapter hangs.

Update 4

Does anyone knows where can I find diagrams schematics of the motherboard of an iBook G3 800 MHz?

Her battery had 450 cycles or so.

Now I know I am taking my chances on a used battery from eBay, but the seller deduced that this battery has less than 100 cycles. He explains that it came out of a broken computer and is 'good as new.'

I plugged it in cold to her computer today and the cycle count was 732!!!

So I am going to calibrate the battery of course, but will my cycle count change after calibration? And if not, what can I do to determine the true cycle count? Maybe it is 732, but if it is, I think I want my 20 bucks back.

Thanks

I suggested disconnecting AC, remove battery and let dry for 4 days. No change. Is it possible that incorrect reassembly could contribute to this? Is it possible that the battery connector has failed? My gut says it's the logic board. I am trying to diagnose this for my daughter and do the fix myself. I have extensive PC experience, but not Mac. I would appreciate your comments and will answer any questions you might have. Thanks!

My computer can boot with or without the power adapter and can be charged for about 20-30 minutes before the battery is suddenly no longer recognized, giving me the message "no batteries available". The computer continues to operate until I unplug the AC adapter, at which point the computer goes to sleep until the AC adapter is plugged back in.

ADDED NOTE: If I shut off the computer, remove the battery and put it back and then push the power button, the computer will turn on and operate as normal. The battery sometimes becomes immediately unrecognized when the AC adapter is plugged in and at other times takes 20-30 minutes.

The battery button tells mehow much the battery is charged and the battery in fact is still chargeable. The only problem is that after 20-30 minutes is that I get the "no batteries available" message. (the adapter light goes green at this point, btw)

I have already attempted to reset the SMC and I do not think that the battery is the problem. What do I need to do to fix this problem?
