how can i get my macbook pro to charge using a inverter sometimes it will charge and sometimes it wont works fine when plugged into a ac outlet in my home

I recently took apart my macbook to see if I could get my wifi antenna nudged to work better. It does seem to be fixed, but when I put the laptop back together the inverter cable shorted to the frame, smelled like burning electronics and stopped working. However, I put a new inverter in and it is not fixed. I was careful to note that the second inverter did not create any smell, but the screen did not even light up for a second. The LCD IS still working, as I can see everything on the screen if I shine a light on it. Except for no backlight, the computer works fine. What could possibly be wrong, and what are my options?

Found the following : On amazon Hypershop's car charger I'd like some flexibility, so the Hypershop one is out of the question (being able to charge my android phone separately from laptop, my backup pc laptop, etc). So my question is, what inverter are you using? I found some on best buy (Cyberpower), but there's no wattage listed in their specs.

When I first tried to change out the inverter it showed light for about a second then went blank. Now nothing at all. What should I look into yet?

To begin with, I own a MBP Intel Core Duo 2.0/2 Gigs of ram. I've had this laptop for roughly 18 months and do not have Applecare. I take extreme good care of all my stuff and still baby it till this day. I have NEVER bumped the laptop against anything, accidently dropped it too hard on the desk or anything similar along the lines. Essentially, looking new. About 2 days ago, I was working with my laptop and I closed the lid which made the computer go to sleep. Everything all normal & no appearance of anything! Around mid-night, I opened the MBP's lid to check my email. (Computer awakes, I can hear the Superdrive awake) then boom, a blank screen. The monitor did not turn on then burn out, it was always off. Similar to if you dim your monitor all the way. I can still see the desktop however, there is no light. If I take my flashlight and point it to the desktop, I can see everything. I called a few places, and they described it is the Inverter board or could be the fluorescent bulb that is damaged. My reasoning for the inverter board is faulty is because when a fluorescent bulb goes out it, it tends to flicker at first. Researching this forum, I noticed most MBP users LCD's that go out, they flicker but, mine just went out and I can still see the desktop. Where can I order the inverter board? I tried [URL] but they're out of stock. I will change the inverter board myself because it will be quicker and I need to use my laptop. It is currently hooked up to an external monitor until I can get this fixed.

View 2 Replies View RelatedI got a cheap 1.42ghz 512mb RAM, 14" screen G4 ibook because it had a broken hinge. I tore apart the laptop and replaced the hinge (screen frame) and put it back together. The screen wouldn't work. I opened it back up and found that the video connector was lose, so I connected it and put it back together. BAM!! Everything worked... everything except the sleep feature when the lid is closed. So I opened it back up, took the magnet from the old frame and put it on the new frame (which was missing its magnet).
When I turned it back on the screen was blank/dark. It showed all the signs of classic inverter board burnout (dark screen, can be seen with flashlight from behind, can be seen on external monitor), so I ordered an inverter board and when it arrived, I swapped it out. Still nothing. The next idea would be the backlight, but that doesn't make sense... I'm trying to figure out what might have happened to make the inverter/backlight go from working fine to not working when all I did was removed the screen back case, screw on the magnet and close it up. I have done a bunch of digging around under the hood and am wondering if anyone knows of a possible ground wire, other connection, easily broken wire, or other issue that might have happened. I'm thinking that it might be one of the power wires that goes into the inverter. It might have broken inside the shield, or maybe I was sold another bad inverter board.
So:
Assumption 1: one or both inverter boards are good.
Are there any connections other than the inverter data/power cable from the mobo and the cable from the inverter to the backlight?
Does anything else (backlight, etc) have to be grounded? Where are these groundings?
Would anything else give the same symptoms except the inverter?
How can I test the backlight? I heard that there are two lights in these machines, so if it was one of the florescent lights, only 1/2 the screen would be dark.
Assumption 2: Neither board is good and that is the problem.
How can I test the inverter board (short of an osilascope) to see if it's working?
Is this a good assumption?
I'm about stumped right now and haven't found any direct help on forums. I'm hoping someone in the Mac community has run into this or has an idea about what could be going on. I'm really hoping that I missed something like replacing a screw that is also a ground or something along those lines.
I have a tough one regarding an iMac G5 ALS 17" 2Mhz I am fixing. First I want to point out that I am familiar with the innards of these ancient beasts as I have fixed a couple 1st gen iMac G5 as well as iSights and Duos.
When I plug in the cord in the PSU, the 1st diagnostic LED comes on but when trying to start the computer the second diagnostic LED comes briefly on and then goes off. Nothing else happens, no chimes, nothing. According to Apple KB this is the sign of a faulty PSU. Yet, I have tried replacing the PSU and I get the same result.
Now the weird part is that if I unhook the LCD cable the computer starts normally (it chimes) with the display off. What is most puzzling is that it will start with the inverter hooked up but the LCD display cable off but will not start with the inverter entirely taken off but with the LCD cable on. It seems that it is the LCD itself that prevent the computer from starting. I thought the inverter would draw current but not the LCD itself so it's probably something else.
Anybody had anything similar happen to them? Could it be that the inverter is faly but it only draws when the LCD is hooked? Could it be some kind of short in the LCD or something that make it draw even with the inverter unhooked?
Does Applecare cover the replacement of the backlight bulb and inverter board? Looking at a PowerBook that has Applecare - The screen in the listing picture is not too bright. The seller has stated that all is well with the screen, but you never know. I am prepared to go for it if the Applecare covers the screen lighting. Applecare cover on notebooks appears to be worldwide - If the screen lighting conks out overseas, I can get it fixed at the local Apple Store?
View 5 Replies View RelatedThe jack on my magsafe charger ripped off a few years ago and before that happened, it must have shorted something inside my macbook as it would not charge any battery afterwards with any new charger. The battery in the upper right corner showed up with an x, the light on the charger will go from a bright green to a dim green right when I put it in and since then the hard drive broke as well, which is why I haven't made much of an attempt to fix it. My question is, What's wrong inside the computer (i.e. logic board, battery connector) and what any of your opinions are. If I can fix it, what piece will I need to buy and would it be worth or should I just sell my macbook?
View 3 Replies View RelatedIt's still quite new. I got it in November. I gave it it's first full charge and it worked fine. The battery died once and since then it won't charge. I plug it in, the green light comes on, I can use the MacBook, but the battery won't charge. As soon as the charger is disconnected, the MacBook shuts off immediately.
What happened? I've tried multiple different outlets. Ones in my house, one in my friend's house, and right now I have it plugged in at Panera and it still isn't charging.
Went to charge up my notebook and said 'not charging'

I just bought my MacBook Pro yesterday. And I plugged it in this morning to try and charge it. The battery indicator up in the menu read not charging. The light on the charge did show up though.

View 2 Replies View RelatedDoes it matter if I'm charging my MBP even when it has full battery and I am currently using it? I.e. using the charger instead of using the battery? My friend did this with his laptop and when he after 1-2 years tried using the laptop without the charger he got like 30-60 minutes of battery time. I don't want this to happen to my MBP.

Our old battery said it was needing to be replaced and my dad went out and bought a new battery for our 15" MBP from 2008 - running SL. I've put it in, it works, I've plugged the power cord into it, and the little light that indicates it's charging doesn't turn on. I checked in the menu and it said the battery isn't charging.
I've already pulled it out and then put it back in, shutting down of course. And I just tried resetting the SMC which has done nothing. It's not under warranty. I've just put the old battery back in and it doesn't seem to be charging it either. I'd be curious if the power cord was faulty, but it's powering the MBP at the moment.
ijust calibrated my batttery and my charger light is green which signifies its not charging anymore..and the icon at the top of my screen says charged..BUT Coconut battery says my current battery charge is as follows:
Current Battery Charge: 5807 mAh
Maximum Battery Charge: 5853 mAh
@99%
Current Battery Capacity: 5853 mAh
Original Battery Capacity: 5770 mAh
@100%
Additional Info:
Battery-Loadcycles: 6
Age of Mac: 7weeks
Charger Connected: yes
Battery is charging: no
so my battery charge is stuck at 99% and its been plugged in for the past 3 hours, and its saying my current battery capacity is higher than my original battery capacity.. is that normal?.. i cant seem to get my battery to 100percent and its not charging..
here is a screenshot of coconutbattery after calibration, i just got my macbook last week..should i be worried about the battery at all?
1) When you first get your Macbook Pro, should you let the battery die out completely and then fully charge it? Or should I charge it fully first? Or what? I don't want to mess up the battery with the first charge.
2) Do you leave your Macbook plugged in while you sleep, are not using it, etc? Or is that bad for the battery?
3) I've heard somewhere that it's bad to shut your Macbook off when you go out/go to sleep. Would it be wiser to just set it to "sleep" and keep it plugged in or something?
Power cord will not light up and charge battery on my mabook. I have already taken the battery out and gone through the steps for resetting. Worked along time ago when this first happened and now its not. Do I need a new battery?

My MacBook Pro's battery died yesterday, so like I always do, I put it in its charger. But for some reason, the LED light won't turn on.So therefore, my computer won't charge. I purchased my MacBook pro in July, so the battery shouldn't be replaced now And when I use my charger on my friends MacBook pro, it works fine.

The only method I have to charge my laptop on my boat is by a 115V outlet. Both the power converter for the Macbook and the wall socket work fine, and so does my battery, but I think that there may just not be enough power. Is there any way to keep charging my laptop? Possibly a product that will produce either enough amperage or voltage to continuously charge my laptop? I'm going to need to be out on my boat for continuous periods of time for a research project.
