Same problem as original poster - with a HDD or SSD in the drive caddy where the original ODD was located one core of the processor goes high use and causes fan to run beserk! I have a HP Probook 470 with a SSD in the original SATA bay, and another SSD in the M2 bay (OS installed here), and the third 1TB HDD in the ODD bay (via caddy) SO the problem isn't the HDD or SSD, but perhaps presumably some reg setting? Incidentally (second poster), my bios does recognize whatever drive is in the caddy Anyone with some suggestions for a solution?
So it is possible to patch this DSDT acpi to make it work properly? I'll try google, put pointing me in the right direction would be neat.
it happened to me after update to CU, whit the anniversary update all went good, now on idle i have 20% cpu use. I have a ssd 120gb as primary drive and a hhd 1tb installed in a caddy
i learned of it in osx hackintosh forums. since it works in linux id say its OS or in dsdt _OSI related to sata eject code first check if its win 10 issues.. run services.msc and start Device Install and remove from device manager the second then reboot
@OLLIW Mate, my caddy is the same as yours (with the hidden switch in plain sight!) so I set it as you advised with the same result!!!! Many thanks for posting a solution/fix to the problem.
totally fixed, my caddy has tree switch potitions, just change to the middle one and cpu usage changed to 2%, Thanks !!!
Just created an account here to say thx! Was searching for a solution allready for 2 months. Switch in the middle position was also the solution for me Big up!
Thankfully mine doesn't have a switch. I just "plug and play". But what I did was I switched my disks --- put the HDD in the caddy and the SSD in the main slot.
Thank you so much! Put my HDD in a caddy some weeks ago but wasn't aware of the switch and didn't think this CPU problem was due to the caddy. My laptop is silent again, what a relief!
