Но!

Покупать у Apple очень дорого, использовать переходники не очень хочется.

Transcend производит такие накопители (JetDrive 820, 825, 850, 855).

Внешне они похожи на blade ssd, количество контактов абсолютно одинаковое.

Но по непонятным причинам Transcend про поддержку iMac ничего не говорит.

Пожалуйста, дайте ответ на самый главный вопрос: если я куплю pci-e ssd JetDrive 820, 825, 850, 855, он ПОДОЙДЁТ или НЕТ?

Hello. Please help me finally understand the choice of pci-e ssd. I'm ready to disassemble the iMac and replace it.

But!

It's very expensive to buy from Apple, it's not very desirable to use adapters.

Transcend produces such drives (JetDrive 820, 825, 850, 855).

Outwardly they look like a blade ssd, the number of contacts is exactly the same.

But for some reason, Transcend does not say anything about iMac support.

Please answer the most important question: if I buy a pci-e ssd JetDrive 820, 825, 850, 855, will it PICK or NOT?

в связи с этим я решил заменить матрицу на новую но появилось два вопроса:

- существуют ли в принципе оригинальные матрицы и как их отличить от подделок?

- не появится ли пыль при установке новой матрицы?

для меня это важные вопросы, поскольку занимаюсь цветокоррекцией - для меня крайне важно правильное отображение цветов, и отсутствие пыли на экране.

заранее - спасибо!

добрый день! у меня такая проблема! монитор не фиксируется и как бы я его не старался поднять вверх он автоматом опускается вниз до конца! стоит на родной подставке "ноге"!

подскажите как можно исправить?

и если это сервис будут ли снимать экран чтоб внутри делать крепление?

English: Stand is not staying in the right position!

Good afternoon! I have a problem! Monitor is not fixed, as if I had not tried to raise up it automatically drops down to the end! stands at home base "leg"!

Can you tell me how can I fix it?

And if I need to remove the screen to get inside to the mount?

But what I don't know is if I can only upgrade to a low power chip (S suffix) or if I can upgrade to a full power desktop chip (no suffix). I've seen people upgrade their i5 2400S 27" iMacs to i7 2600, but I've never seen anyone tried a CPU upgrade on a 21.5" imac before let alone the highest end CPU offering from Apple on the 21.5" Mid-2011 iMac is only an i7 2600S.

Now the performance difference between the i7 2600S and i7 2600 is negligible for me, but the problem is I can't souce any i7 2600S but I can fine loads of people selling their i7 2600.

So if anyone can answer, please do as I will apreciate it greatly and if anyone is selling or knows someone who sells an i7 2600S that can ship to Indonesia please answer too. :) Thanks in advance.

Turns out iFixit sent me one too many adhesive stripes of the same type and left the other one out. Iam missing the 02 adhesive strip and have the 01 adhesive strip two times.

I have now cut it in proper form and was wondering if I would have to redo this job once ifixit will provide replacement.

I couldnt leave it open and the glass laying around as I got a little kid at home.

here are some Images:

looking forward to your replies. I really dont want to do this again. It seems like it would only be 2/3% of the adhesive strip missing, I personally think its fine as it will stand on a desk and be rarely touched.

Thanks in advance!

When I connected an external VGA monitor, I saw it did boot to the “No boot device” screen, which was expected since the original HDD was removed due to failure.

Eventually a MacOS install CD got stuck, so I opened it up and removed it manually. After that, the behavior changed. It now chimes with the green power LED, then as the external monitor briefly detects a signal, it shuts off.

If I try again right after, the power LED comes on but nothing else happens. No chime, no video, nothing until I power it off manually. After unplugging for a few seconds and plugging back in, it goes back to the initial state where it chimes and then shuts off when it should show video on both CRT and external display.

What can I do? I replaced the PRAM battery and it made no difference. It also shuts off before I can do a PRAM reset (Opt+Cmd+P+R), and the physical PRAM button hasn’t helped either.

Trickle voltages seem normal, but when it reaches the “power LED only” state, the down-converter board trickle voltages are lower than normal.

I can also hear the high-voltage crackling as it powers off, so I assume the CRT is receiving power in some way. One other thing of note is that either the speakers, or the down converter board make a high pitched sound, I'll attempt to identify the source later today.

I am planning to upgrade my iMac (27 inch - mid2010) which is now 10 years old and running on El Capitan 10.11.6 OS. Since its having a good CPU (i7 2.93) I am considering replacing the stock HDD (1TB) to an SSD, and maximising the RAM from 8GB to 32GB.

1. is this upgrade worth it? and will I notice a different when using it?
2. for the RAM upgrade, I think this part is the best option (iMac Intel 27" (Core i5 or i7) EMC 2390 (Mid 2010) Memory Maxxer RAM Upgrade Kit)?
3. for the SSD, I was reviewing this guide (Mac Intel 27" EMC 2390 Hard Drive Replacement), and I am confused about the parts options. the SSD Upgrade Bundle with Crucial MX500 SSD 1TB, or buying 2 TB SSD Segate Hybrid 3.5" Hard Drive with all the required tools separately which will almost cost the same. my concerns are:
   • is the two SSD mentioned having the same performance?
   • is the two SSD mentioned having the same certification with my iMac?
   • is there any drawback for using Segate 2TB over Crucial 1TB?

**

This is my first time upgrading my iMac, and I really appreciate if you can guide me in selecting the best parts to get the most performance out of it for the longest period.

Regards,

I got horizontal lines over the display! During the warranty period they replaced the board ( it blacked out ) and now this is happening. They refused to replace the device saying out of warranty and asked to replace it :-|. They were not even sure that changing the display will fix the issue. I am hesitant to replace the screen as I am better off to buy a new one rather keep repairing the faulty product.

Is there any way to fix it?

Tried
- Reinstall the OS
- External Display = Works fine
- Reseating those 3 cables

Lines kind of flickers, may be some lose cables?

Please help
