Spontaneously locking SSD with ATA password?

The situation is a brand new laptop Lenovo b590, a brand new SSD OCZ Vertex450 128Gb, ​​Win7 + firewood + software is installed, everything works perfectly.
The laptop was used for about 2 days. In the evening of the 2nd day it was turned off, after which the next morning it refused to boot and began to ask for a password at a stage when it was still impossible to even enter the BIOS. Using the method of scientific poke, it was found out that the SSD is blocked. After installing the standard hard drive (it was removed and replaced with an SSD immediately after purchase), the laptop stopped asking for a password. When installing an SSD in another laptop (Lenovo Thinkpad x120e), it starts asking for a password at startup.
While trying to delve into the locking technology, I found out about the existence of an ATA password. Essno, I didn’t climb in the BIOS, I didn’t set the password for hard. That is - "it itself!". During the experiments, it turned out that if a password-protected SSD is inserted, it is not possible to get into the BIOS of a laptop and netbook at all. If the disk is pulled out, the BIOS is available, but all passwords are disabled there.
And now what makes this story a little more interesting. When installing an SSD in a regular system unit, it asks for a password, but after pressing ENTER, the system boots. And gives read and write access! That is, I created directories in the FS, copied files back and forth - everything works. The OCZ utility tried to make safety erase - it says that the disk is locked.
It can be assumed that pressing ENTER when prompted for a password is equivalent to entering an empty password, which is perceived as correct - but this trick does not work on a laptop and netbook. There are no items related to disk security management in the bios of the system unit, otherwise it would make sense to try to “change” the password on the hard drive from empty to empty, which would disable it.
Google suggested that if the disk is already locked, then it is locked, no read-write operations are allowed. And in this case, only a special piece of iron called pc3000 saves. But I have access to the FS! What kind of blocking is this, and is it possible to bypass it using software methods?

Isn't this under warranty?

I have a "wild version", but you never know. What if the default is one language for the desktop, and another for the laptop. And the password in some magical way clings to it.
It is clear that the probability is extremely small, but you never know.

ON IDE screws, this happened with poor contact or faulty hardware. Perhaps it's the same story here? And an empty password, for example, is allowed to be entered on the desktop, but not on the laptop: such are the features of the BIOS.

The Lenovo ThinkPad has the idiocy of built-in encryption. Often non-disabled. This can be in the BIOS if it glitches. They often have a hard lock immediately from the factory, and it’s just stupid to change it.
You can remove the password using Victoria or MHDD, PC3000 is not needed, they can also show the lock status.
