Hello. sorry for my English - I use the translator. I have a problem with y510p. And in the course of the experiments, I came to the conclusion that the problem is in the BIOS. When I replaced my hdd by ssd crucial_M4 he does not appear in the list of devices in the BIOS. However, when you boot from the ssd cache 24G (on which I installed 8) crucial_M4 available in Windows Explorer and in disk management. I tried to change all the settings in the BIOS but crucial ssd and has not appeared in the list. On other computers crucial_M4_ssd is displayed in the BIOS. You can record crucial to the white list. Thank you.
