iPhone 5S iOS Trouble: 34% to 0% in 2 mins

August 26th, 2016 - Comments Off on iPhone 5S iOS Trouble: 34% to 0% in 2 mins

iPhone battery or my iPhone 5s iOS is having trouble. I suspect it’s iOS.
Two nights ago after a day on iOS 9.2.1 of Low Power Mode, I shut off my iPhone 5s for the night with 34% battery remaining. When I turned it on in the morning, it started gathering data and shut down because the power was exhausted. I saw, in the many screens, a 10% warning, and the battery indicator went from 3% to 1% before the screen went blank. Argh.

One Last Disassembly: Get the Hard Drive on my iMac

June 20th, 2016 - Comments Off on One Last Disassembly: Get the Hard Drive on my iMac

Having failed at an inexpensive home fix, I’m going to disassemble my 2008 iMac one last time to pull out the hard drive. I’d swapped out the original for a 2.5″ SSHD (hybrid drive). This was before there were 3.5″ SSHDs.  I’ve put a new 3.5″ 2TB in my Dell desktop replacement for my iMac. The extra space will be nice.

With that done quickly, I now get to decide what I’ll do with a perfectly good iMac that has one repeatedly-failing component. Perhaps a performance in front of the Apple Store?

Defeated. iMac is Dead

June 20th, 2016 - Comments Off on Defeated. iMac is Dead

Today, I came back to the project. As much as I tried, I could not get past 1 LED diagnostic light on my 2008 iMac. My iMac is dead.

Final Attempt to Revive my iMac

I put new thermal paste (after having reflowed the GPU months ago) on the graphics assembly, installed it on the motherboard, put it all back together enough to see the diagnostic LEDs, but got no different results.

Resignation and Defeat: My iMac is Dead

I’ve done what I can and have given up hope on my iMac. Owning an iMac was as much hell as owning a Dell, perhaps worse. Maybe I’ll do a post-mortem in another post. There were lots of problems, and Apple has made iMacs are even more disposable now.

Disk Utility Inconsistencies: Yosemite on different hardware does not function consistently

March 26th, 2016 - Comments Off on Disk Utility Inconsistencies: Yosemite on different hardware does not function consistently

Disk Utility inconsistencies could not be explained.

On a 2008 17″ Macbook Pro and a 2013 Macbook Air, both with Yosemite, I had different results. The older hardware could not format/erase a disk while the newer hardware could. Apple agent agreed that it shouldn’t be different, but there it was.

iPhone Photos Are Not Saved

February 25th, 2016 - Comments Off on iPhone Photos Are Not Saved

Case number 1056308635 through chat.
Both with Camera and Camera+ my iPhone 5S stopped saving pictures. I would take photos or videos, and the experience of capturing the images was standard. Yet, when I went to look for the photo or video, it was not there.
I lost data, like what used to happen with Windows.
Turns out that simply restarting the phone fixed the issue of disappearing photos in my iPhone.
‘nuther lesson learned from this: Check Photos/Camera Roll frequently when taking a lot of pictures or important pictures.

GPU Replacement: Early 2008 24″ iMac

October 29th, 2015 - Comments Off on GPU Replacement: Early 2008 24″ iMac

I’ve documented the resources I used to repair my Early 2008 24″ iMac (iMac8,1, EMC 2211). I really need to do a GPU replacement, but I’m going to try some steps before that.

NVIDIA GeForce Fails, Again

The NVIDIA GeForce 8800 GS graphics card (GPU) failed again on this iMac. It doesn’t make sense to put the money into having the GPU professionally replaced given the age of the machine. The iMac is long in the tooth, but otherwise very functional.

Apple Store Not Helpful

In my quest for a GPU Replacement, I went to Apple Store, Portland, Oregon
Aug. 31, 2015 – Took into Apple Store. Vague diagnosis of either the motherboard or the graphics card. No recall on graphics card. No hardware test could be run, which I did not understand.

Waiting for Time and Focus

Since then I’ve been working, in my own slow way, to get this fixed, reading up and watching videos on the process. Mostly, the iMac has been sitting in its box waiting for summer to end and for me to have the time and focus to get it working.

GPU Replacement: Taking It On Myself

In the last week or so, I’ve had it apart, taking the tasks in chunks as time allows. I took out the NVIDIA GeForce 8800GS GPU and reflowed it. Putting it all back together, it didn’t work. I had one LED when I plugged it in, and it went to zero when I hit the power button.

Round Two

Round Two in getting a GPU replacement is more work with the same equipment: I’ll try turning the machine on without the graphics card, relying on the on-board GPU. If that doesn’t work, I’ll try re-reflowing the NVIDIA GPU.

11/11/15

Tried without the old GPU with the same results: One LED diagnostic when I plug it in, then zero when I hit the power button. 🙁 Not being able to fix this really has me down.

 

Fixing iMac: Resources for repairing a 24″ iMac

Failed NVIDIA GPU

As I noted, my NVIDIA GeForce 8800 GS GPU has failed on my “Early 2008″ 24” iMac [iMac8,1 / EMC 2211]. I’m going to try to fixing my iMac. Below are some of the fixing iMac resources I used.

1. Reflow Existing Graphics Card

My first step is reflowing the existing graphics card. Reflowing is melting the existing solder in place. Since solder has become lead-free, it’s more brittle. If the solder cracks, simply melting it can create a new electrical connection. Needless to say, reflowing should be a last resort. You should know the graphics card is bad, and that you will be throwing it, or the whole computer, away otherwise. I’ve been warned that reflowing can ruin as often as it saves. Research online has revealed that this can be a relatively low-cost way to restore the GPU and any otherwise functioning computer.

  1. I bought a used toaster oven at a thrift store. I had to read just one warning about potential hazards from heating electronics to convince me that the $15 was worth it. I’ll use the soon-disposable toaster oven outside, thereby not contaminating myself nor my cooking oven.
  2. I got a little kit with (for me) the next level of computer repair equipment.
  3. I ordered heat paste.
  4. I looked at videos online to see what I was getting into.

2. Replacing NVIDIA GeForce 8800 GS Assembly with a New or Refurbished Assembly

Since this is a record and a log, I’m hoping I don’t have to take this step. Will expand if I do take this step, though I imagine it will be easy, having once already disassembled the iMac to remove the defective card.

iMac Graphics Card Failed, Again

September 16th, 2015 - Comments Off on iMac Graphics Card Failed, Again

My early 2008 iMac is perfectly fine, except the graphics card has failed again. The ATI Radeon HD 2600 Pro graphics failed three times. I paid to have it replaced once.
So I asked Apple what’s different.
Case-939 389 471
No replacement program for chip. “Known good card.”
That answer for me is that I should expect the same turnover of hardware with Apple as with the likes of Lenovo or even Dell.

iPhone Orientation Issues fixed with iOS 8.3?

iPhone 5S with the text/message area in landscape mode and the keyboard in portrait view. Closing app and opening fixed the iPhone orientation issue.

Took this screen shot of iOS 8.2 just a few days ago. Today I read that iOS 8.3 is supposed to fix iPhone orientation issues like this. I’ve gotten them often, so I hope so. Sometimes I can’t get it to rotate back, and other times, only some of the element rotate.
Apple provides this information about iOS 8.3.

Apple USB SuperDrive Incompatible

March 30th, 2015 - Comments Off on Apple USB SuperDrive Incompatible

Since the SuperDrive (built-in optical) drive on my iMac is wonky and my MacBook Pro’s is even wonkier, I got a Apple USB SuperDrive. It doesn’t work on either machine.
Case ID: 772329682
Apparently the Apple USB SuperDrive, which is USB 2.0, is not backward compatible with the Apple USB 2.0 in my iMac and MacBook Pro. Support supposed that it might be the firmware, which means that Apple should be able to fix it, but won’t.

Planned obsolescence? I think so. Every other USB device works with my Apple Macs.
Here’s the link showing compatibility: https://support.apple.com/en-us/HT202665. The web site shows the requirements, but the Apple Store does not.
