Hello
I can confirm that this problem also occur in our businnes. We have previously used the 520-series with no problem. When started using the 530-series all the computer that uses this disk cannot reboot, but be turned off completely.
We have standarized on HP laptops and I have changed to 530-Series on several models. All have the latest BIOS and SSD firmware. Fast Boot or enable/increase Hard disk Pre-delay is not available in BIOS on these computers.
A fix would be appreciated.
