MacBook :: Won't Turn On After Install New Inverter
May 29, 2010
i just installed my new inverter and put evertyhing back into place. tried turning it on and no reaction. There is no sign of turning on, no sounds or light to show. I thought i may have damaged the keyboard ribbon but there is no physical harm that i could see.
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?
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
Searched the forum, some useful information. 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.
If I wanted a portable charging solution for my 13" 2010 MBP. [URL:...] I'm not sure about the amount of power this product supplies, etc and whether or not those types of specs will be compatible with my MBP. if someone could advise as to what would be best.
I've got a MBP and will be charging two iPhones off of it most of the trip. How big of power inverter will I need? [URL:..] will this provide enough juice?
Found a macbook on the cheap. It boots and works via external monitor but the screen has no backlight. I've tried a couple inverters that I know to be good. 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.
My MacBook won't turn on. I hear the noise (not from the speakers but from the inside, like the hdd or something) but nothing shows up on the screen. I tried to boot from the Mac OS X install disc, but now the disc is in there and not coming out, and when I turn the computer on i hear the cd/dvd drive instead of hard drive.Still nothing on the screen. This is a follow up to the behavior I described in this topic:[URL]
I have intalled the new version of LION OS and since this moment, my Mac refuses to turn on. The same white screen appaears with the apple and the little thing which is turning again and again. Please help me I don't know what to do
i was wondering if anyone would know of a place to find an inverter board for an imac g4 as the screen blew out. ive been searching around ebay with no luck really. If anyone knows of an alternative to ebay or anything
I 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?
I bought a powerbook off ebay, it worked but on startup occasionally a folder icon would appear. I rebooted from the original discs which seemed to do the trick. However the original discs are too old for many of my apps, so I bought some newer install discs (osx 10.5) I put the install disk in and got the panic message 'panic: Im hanging here'
The answer seems to be to run a disk repair (am i right?) However to do that I need to eject the install disc, I can't get the install disk out and of course it keeps tripping up everytime I start it. There is no secret little button to eject the disk manually. I have tried holding down apple and S but the install disk over rides everything and trips the mac up. I think ill be okay if I can just get this disk out.
I can't install CS5.5 form disk to my new macbook pro.The error message says turn off safari Notification.I've turned these off in the safari preferences and also tried turning them off via Activity Monitor.
But I can turn it off, if I choose "Share my internet connection for other units". (I don't know, if this is the right text in english, because my OSX is in german)
2) Now Bluetooth is OFF:
But I can't turn it on, because the checkbox "ON" is inactive.
It turns only on, if I choose "New Unit"(?). Then there is a new window, that says, that this is only possible if Bluetooth turns on. If I say OK, bluetooth turns ON.
Back to 1)
What's the problem. Why is this f* checkbox for turning bluetooth on and off inactive?
This is not a hardware problem, because I can have stable bluetooth connections.
I did a smc and am pram reset. But it doesn't help.
Had (used) iBook G4 several months now & thoroughly enjoy it, even tho' I live in the sticks where there's no hi-speed/wireless available; I connect to internet & power, which is fine.
This weekend I went to turn off my iBook & it wouldn't turn off. It's now permanently on, with opening info barely visible (like I need to click on F2 to brighten up, except nothing happens).
Currently using my "back up" computer, my iMac Grape, which is pretty much an antique by now.
I was playing around with my mac g4 logic board... ( yes, i know... ) anyways, i press the power, the light turns on, and the fan spinns up then everything just turns off... http://docs.info.apple.com/article.html?artnum=95035 ^ my tower, (agp graphics, ftw)
This is the first time i reinstalled(clean install) my snow leopard on my MBP. All went fine but then i inserted the disc for bundled application (which contains the ilife apps) but it keeps failing.
It says that "the installation failed. the installer encountered an error that caused the installation to fail. contact the software manufacturer for assistance".
I've also done my research on this matter. I've gone thru a few steps i tried as below without success:
1)normal install - fail
2)repair permission - fail
3)install in safe mode - fail
4) install using another admin acc - fail
5) made an image out of the disc and install - fail
6) used a similar disc(my dad's since we have identical version) - fai
7)updated my system and install - fail
8) reinstall the mac - fail
i cant think of any other solution as im a bit noob when it comes to mac. is there any other things i could try before taking it Apple?
My MBP was recently squished in a motorcycle accident and its hard drive and superdrive were destroyed. Is it possible to buy a new hard drive, put it in an external USB 2.0 enclosure, then install OS X on it using the discs that came with my destroyed MBP in a different Mac, then put the hard drive into the squished computer and have it use that hard drive as its startup disk? The motherboard on the squished computer is fine, I just can't install OS X on it because it has a broken superdrive.
I have an aluminum Macbook from late 2008, model A1278. I just had to replace the hard drive, and need to install an OS on the currently blank HDD. Problem is, my CD drive doesn't work, so I can't just install from a disc. I had installed Mountain Lion on my old hard drive, but the original OS was Snow Leopard. I haven't succeeded in getting any of my information off my old HDD. Is there another way to install either Snow Leopard or Lion onto my new hard drive?
i just bought a macbook pro and i want to do a clean install but it didn't come with the install disks. is there a way to do it without buying new disks?
Did a search through here but couldn't find anything concrete. What are the differences between a fresh Snow Leopard install and a factory Snow Leopard install? I ask because I bought an Intel SSD and don't know if I should bother cloning the hard drive that will come with my new 15" MBP or I should just install a fresh copy from a Snow Leopard install disc. I'm aware macs come with next to no junk pre-installed, but are there some factory settings that are worth preserving if they aren't documented well?
I tried to install Snow Leopard on my MacBookPro but it cannot install and cannot be ejected. I need to eject.
The reason for this is a long story. My logic board was replaced and my Mac was wiped clean. I am not trying to recover from back up but could not figure out the next step after the recovery finished. So I tried to install OSX from the disk that came with my Mac. Probably not the right corrective action.
I need to remove the Snow Leopard DVD and finish my recovery.
Im not doing a back up hd i want a new install I install the drive without the screws in the hd,does that matter? I start hold option and only the cd comes up,i click it wait 2 mins then says you have to restart Did this about 10 times,please help before i take this hd out and smash it
I'm new to Mac. I feel I have been suitably rehabilitated from my former ways. I bought a MacBook Pro. It came with an installation disc for Leopard. I'm not sure if it's an image or if it's the OS install DVD. I bought a Mac Pro, quad Xeon 64 bit monster. The guy I bought it from had to retain the HDD for legal reasons. So, I bought a couple of drives that I'll slot in. Question: Can I use the install disc from my MacBook Pro to install Leopard on my Mac Pro?
I have recently done a Time machine back up of my MB Pro 15" then wiped my hard drive trying to clean it up so I could install Windows 7 with Boot Camp. I had my original Install Disk which I forgot was Tiger, Having used one of my brothers company licenses to upgrade to Leopard but that disk is now with him in another country. So now I can not restore from my Time Machine backup. I have a Leopard Install disk for a Macbook Pro 13" which I also own. Is it possible to use this disk to re-install Leopard on my 15"?
I have just come back home and turned on my macbook 2007 model. I was using it fine just 5 minues ago. Then I shut it down. Now It will not turn on. I've had 2 hard drives die before (made clicking noises). My 3rd drive was purchased 1 month ago. Is there any way to determine what's wrong? There have been no drops or obvious physical damages. It just will not turn on. There's no signs/lights or error messages. (the battery has charge and the power cord is plugged in) [i dont have apple care]
