no power

so i figured i would try to install linux on my old 3,1. so i installed an old ssd, popped it in, turned on the mac and nothing. i get a solid white led and no chime. nothing on the usb either, hence no led on the mouse and no caps led on the keyboard. so diving into some of the support forums...

after pulling my G3 to bits and harvesting the analogue board from it I can't visually see anything that has failed. according to someone on YouTube they state if the Flyback is dead it could put a short on the horizontal transistor/circuitry and pull down the power rail, however when I...

After replacing my 2019 13-inch MBP display I tested it before putting about four more screws in. I disabled auto boot before I even started this process. I plugged the battery connectors in and then loosely put back the lower case without putting in the screws. It booted up with the power...

Hi, I’ve just followed along with this video, using OWC’s kit, to replace my Fusion drive (small, old NVMe SSD + 2TB HDD), with a 2TB OWC NVMe, and a SATA SSD. I also upgraded the Core i5 CPU to a 9900K Core i9, as per various threads here, and videos on YouTube. I had no issues with the...

Hi! Guys I'm facing a problem with a late 2013 Macbook Pro. It's a little hard to explain but I'll try. For some reason my Mac when in sleep mode turns off and won't turn on again. Sometimes if I plug in the power cord and click on it will start working again. Also, if you put in the power...

Have a Late 2016 MBP 15”. Last week the screen went black while using it. Did SMC, PRAM, VRAM resets. Hooked up to an external monitor and it worked just fine for a few days. NOW nothing happens. Won’t turn on. Won’t make noise, no fans, no blips nor bleeps. I was prepared to order a new...

I replaced my MacBook Pro 2010 screen assembly as the lcd was broken on the original one. It’s no longer showing any signs of life. The MagSafe cable isn’t lighting up. The battery life light isn’t showing when pressed, it was charged before I started the process of replacing. I’ve tried the...

Hello to everybody, a friend of mine just gave me an iMac G3 (M5521) (slot CDROM, indigo from the 1999), asking to try a restoration. At the moment the machine doesn't switch on at all, so I'm starting to troubleshoot the power board and the power rails. Since now I was able to found only the...

Hello everybody. I need some help, if anybody can answer me. I recently bought a 2009 Mac Pro 4.1, 2,66 ghz single processor. He came with broken PSU, with a pc GPU and no power cord. It was really cheap. I've tested the first time, put a power cord and push the on button. I've heard the...

Hi guys! I have here an cMP, a 1,1 - 2006 (flashed to a 2,1) Mac Pro. Two days ago I left it powered on and a few hours later when I take back to work it's already off and since that moment can't made it powering on again. No signal. No error leds, no sound, absolutely nothing. Already...

I have a dual core early 2009 Mac pro.. I was working just fine till one day it just died over me. After tons of research I figured it was the PSU as the diagnostic LEDs were dead aswell so I gave the PSU to this mechanic I knew and he sort of fixed the issue (I Think) cause after the repair the...

Hi, problem with my 2016 MacBook. Over the last few weeks it’s been intermittent whilst charging on its single usb c port. Sometimes works sometimes doesn’t. Now just doesn’t. Battery is now dead and won’t power even if plugged in. Need to access my files for work etc. Any ideas would be...

I have a late 2008 Macbook Pro that hasn't been used for over a year, that I need to use now because I had to RMA my current laptop. It didn't power on the last time I tried. I just figured the battery was dead from not being used for a while. The charger indicator light would turn on when I...

I have a late 2016 MBP and when I plug it into a charger there is no charging sound, when I try to power up the unit, nothing happens. I had it connected to the charger for about an hour and it felt like the bottom of the laptop was warm indicating that the battery could be charging but im not...

So, my 2017 12" macbook will not start up no matter what I try. Back in september I broke the screen so I replaced the entire top portion of the laptop myself. Now when I plug in the laptop gets extremely warm. I am using my dad's 61 W charger instead of the 29 W charger that came with the...

I just picked up a 17 inch iMac G4 cheap on Craigslist, model number M6498. It doesn't work, and from what I've been seeing, the problem is most likely to be the Power Supply. When the power button is pushed, nothing happens at all, not even the fan spins up. Is this the power supply or could it...

I have a iMac 2011 27", EMC 2429, 2.7GHz, MC813LL/A, and I'm having problems. First one was the display shutting down randomly, likely due to the common problem with this iMac that Apple did recall here. After days of research, I found the most common fix (after the recall expired) was to...

Hey everyone, so I purchased a 2009 4,1 Mac Pro (Dual x5550) on Craigslist a couple weeks ago for $150. Honestly insane deal for how good of condition it's in. I painlessly flashed it to a 5,1, installed High Sierra, upgraded to 32gb of RAM, and installed a GTX 1070. I've had absolutely no...

Hello, last night, out of the blue, my macbook (mac sierra) stopped charging. I was in the middle of writing sth, had not moved/disconnected/ changed anything and at a 27% the battery (needs to be serviced) stopped getting power and the light on the charger went from orange to nothing. I put the...
