    SOLVED! See post #8

    Hi!

    I own a Toshiba Satellite P50a (pspmge) laptop. I recently bought a WD Blue 1TB SSD together with a drive caddy from ebay. I've also done this with a 850 evo 250gb and a HDD. The hard drive gets recognized by W10 and everything, S.M.A.R.T return no errors. TRIM is enabled. It is formatted with NTFS, and have some movies on it. Plex streams just fine from it.

    The problem is that, when I have the caddy connected, the CPU will constantly go high. The process named "System", detailed name "NT Kernel & System" uses about 20-30% of my CPU. I got a i7-4770MQ, so 20-30% is some processing power.
    And that's with no programs open, just W10 idle. This also causes the fan to constantly spin at high speed. And the computer turns warm. But when I remove the caddy (after shut down off course), CPU usage is back to normal again.

    I can't figure out what makes it do that. And I can't find anyone facing the same problem/ bug. Any suggestions?

    Other details:
    In BIOS, in BOOT menu, the caddy with the SSD in it is recognized as ODD, optic disk drive. I think that's a bit odd, or maybe not?
    The caddy runs fine in my HP6530b with Linux. No problemo.

    Does the HP6530b's bios see it as an optical drive too?

    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?

    :(

    its likely to do with the DSDT acpi and the eject code for power management of dvd

    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.

    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.:clap:

    Might be useful to add a big SOLVED to the title of the opening post.
    This is a great clue
