Won't switch on after switching in another laptop's SSD briefly
This 15” MBP is my emergency laptop. But my main 13” MBP (containing all my ongoing files) was having some issues and needed repairing, so — since both laptops run OS High Sierra, and both use Samsung SSDs — I thought I could just take the SSD out of my 13”, put it in the backup 15”, and continue to work off the 15” until the 13” was fixed.
It didn’t work: The 15” wouldn’t recognise the switched SSD (flashing question-mark folder).
So I put the original SSDs back in their respective laptops … and now the 15” won’t switch back on. (It switched on initially, but then powered itself off at some point in the night, and then … nothing. Since then: No power, no light, no chime, no life at all. It’s just acting completely dead.)
- The battery was in good condition before this. I’ve obviously tried taking it out, reseating it, and putting it back in.
- The power cable light shows green. I have left it charging overnight for hours and in the morning … still no life from the laptop
- I have tried SMC reset
- I thought from similar posts (e.g., My Mac won't turn on after I replaced Hard Drive AND Computer dead after hard drive replacement) that I might have damaged the SATA cable. But I’ve bought a new SATA cable and installed it and … nothing. Makes no difference
It’s infuriating. It was fine, and all I did was try to use a different HD – didn’t work and put the original back in – and now the laptop is completely kaput. (And it looks like I’m not the only one having this sort of problem — e.g., After HDD Replacement, Won't turn on)
What could it be??

Be careful here! You'll thrown three different systems out as your sources: Early 2011, 2012 and your last one a much older 2006 model!
While the 2011 & 2012 models are closer to yours 2008/09 there are still enough differences that can be a factor here.

Can you give us a bit more on what your 13" model is as well as the models of your Samsung SSD you are using here.

No, just two systems:
• 15" — Late 2008 MacBook Pro — 2.4 GHz, Core 2 Duo
• 13" — Late 2011 MacBook Pro — 2.8 GHz Core i7
My apologies, they're not both using the same type of SSD. There is a Samsung in the 15" and a SanDisk in the 13":
• 15" — Samsung 860 EVO 1 TB SATA 2.5" Internal SSD
• 13" — SanDisk SSD PLUS 960 GB Sata III 2.5 Inch Internal SSD

Sorry ;-{
You hit the SATA I/O speed issue with your SanDisk as its a fixed SATA III drive in your older SATA II system:
● SanDisk SSD PLUS Fixed SATA III
● Samsung 860 EVO specs sheet Auto Sense!
If you had two Samsung 860 EVO drives you would have a no problems swapping them around!
You can also have the HFS+ Vs APFS issue too!

Hi Dan,
I am about to buy another SSD for a refurbed laptop. I want to know what I'm looking for in the specs with the regard to the above (i.e., not getting one with fixed I/O speed, but making sure this time to get one with "auto sense"). What am I looking for in the specs? When I look at the two links you posted directly above (for the Sandisk and the Samsung) I see no reference to "fixed" or "auto sense" on the spec sheets. What do I need to see?
Thank you!
