17 R4, SSD M2 not recognized in BIOS

Question

Someone I know asked me to change his Alienware 17 R4 Battery, after I changed it, the SSD M2 is not being recognized in the Bios, and it's the OS drive. in the BIos all 3 SSD slots show empty, I tried to change it to the slot and updated the Bios with no luck.

I ran diagnostics and it didn't show any errors.

I also checked the SSD on a different machine using SSD to USB adapter and it worked, so it doesn't see that it's an issue with the SSD itself.

I also tried to change Raid On to AHCI, UEFI to Legacy and no luck.

Any suggestions?

Thank you

I'm starting to get the feeling that you might've damaged something on the board itself to cause the M.2 not to be recognized as it work's perfectly fine on a M.2 to USB adapter.

Have you made sure that all the slots are not responding to the drive?

There are 3 slots, one is a smaller size, but I tested it on the other 2 and neither can recognize it. Everything else is being recognized though (RAM, WLAN, HDD). Thanks for your reply

Yeah it’s a main board issue then since it can’t recognize them in either slot and those aren’t on a separate board so I’d contact Alienware for a replacement if the warranty is still on the laptop but if not, I’d buy another computer.
