no chime

As part of my quest to get my 7,1 to run Linux (seemingly impossible at this point) - I decided it would be a good idea to pop my OWC 4M2 into my 5,1 to see if I could install Linux onto one of those drives and then install it back into the 7,1. The 5,1 is running a fully up to date version of...

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...

I had the idea to attach a Thunderbolt 3 drive (or an external SSD with an USB-C interface) to my iMac 27" Retina Late 2015. So I took my Apple TB3-TB2-adapter, a TB2-cable and a LaCie Rugged Pro Drive as well as an Icybox USB-C Case with an SSD containing bootable volumes and happily tried all...

Hi, I am not an electronics' specialist. A week ago I replaced the battery in my old but perfectly working MB Pro. This was its second battery change since purchase. The new battery was aftermarket but listed as "original"! After connecting the charger, the LED on the Magsafe lit up green...

Has anyone ever tried to upgrade CPUs on a 2010-2012 5,1 Mac Pro using delidded CPUs? Reasons could be either thermal performance, recycling a pair of CPUs coming from an older 4,1 Mac Pro (the dual cpu tray needed delidded CPUs), or just for science! I tried this experiment, upgrading a 2010...

When trying to turn on my G5, the power button will light up but immediately goes out after I stop pressing it. The fans come on but no boot chime and nothing on the monitor. The fans speed up to full speed after about a minute. The air blowing out of the machine is room temperature and never...

I recently got a Dual 1.25 MDD off of eBay which describes as a restoration project. The system powers on but no chime. After about 10 seconds, the fans go full blast. I've done the following: - Replaced PRAM battery - Reset PMU - Reseat video card, RAM, and power supply connector to...

Hey everyone. All of a sudden my 5,1 died. I can't get it started again and I've tried all the basic stuff like restting PRAM, SMC etc. Took out all the drives, graphics card and even changed the ram sticks around (also took them all out at one stage). The power light stays on and only blinks...

I bought an HP Quadro FX 4500 and flashed it for use on the G5 per instructions on the macforums. The flash didn't work, it resulted in a black screen on the G5. I put in the old video card and heard a chime but no video. I tried to reset the board by pressing the switch same response . I...

Hi all, I have an early 2011 15" Macbook pro, yes the one with the graphics issue ?. Keeping this one alive has been a real struggle, having Apple "repair" it on three different occasions before they accepted fault...anyways I'm having a new issue that is leaving me scratching my head. Several...

I've never had the battery run out of any computer so I don't exactly know how to diagnose it; I just know that the computer might not remember its time/date while starting up offline, but I haven't noticed any clock weirdness so far. The iMac has been starting up without the startup chime for...

So.... I usually leave my MacPro on 24/7 so I hardly reboot unless I need to update. One thing I noticed when rebooting is the startup chime, I never hear it. It didn't occur to me before. I did a nvram reset and I hear the chime and it boots all fine, but once I do an another reboot or...

so i recently have a board with no chime ( 820-3115 it must be a A1278 from 2012 ), following the circuit schematic i found that component U6100 does not have voltage in 5 & 6 pins, those are for SPI_MLB_MOSI and SPI_MLB_CLK, i follow the trace until U1800, all traces have continuity but...

Hi everyone, I am new to using older Apple products. Few days ago I bought a used Mac pro 1.1 It works fine with Windows 10 already installed by the previous owner. But I want to install MacOS, but there is no boot screen/chime, it boots directly into Windows. I can hold the option key how...

iMac 17” 2 GHz A1208 does not boot, no chime, no fans or other mechanical activity. Opened it up to see the diagnostic LEDs. Upon plugging in, LED 1 lights up normally, and LED 2 lights up at about half brightness and before I touch the power button. I have not been able to find any...

Hello everyone, I searched quiete a lot of Forum-Threads to figure out a solution...with no result yet, thats why I want to ask you guys for some help. First of all, I got a iMac mid 2011 21,5" with 16 GB RAM, but no HDD into it anymore (by the former owner removed). So actually I started...

2010 Mac Pro 5,1 2x 2.93ghz Westmere 20gb RAM OWC 256gb SSD ATI Radeon 5780 The last time this system booted (at all) was just before I took out the GPU to try in another Mac Pro. Once I reinstalled the GPU: - system starts up - front power button light illuminates - all fans run - gpu...

I am having a weird issue after I updated the CPU's on my Mac 1,1 to the quad core from the dual cores. If dimm 1 on the lower RAM board is occupied the system does not boot. The system turns on and the fans turn on as normal however there is no video out put and no chime, the white front LED is...

My 4,1 / 2009 unmodified dual proc Mac Pro was having intermittent crashes (every *other* boot, it would randomly freeze). I took the CPU tray out and discovered a wiggly northbridge heatsink that needed to be refastened to the board. Taking off CPU-A to get to it, I noticed the thermal paste...
