The motherboard battery was dead so it would lose the clock and BIOS settings. The BIOS version was very old. I don't think they did anything to "renew" the machines. Simply plugging it in would show a message saying the battery was dead. Maybe that's why it's cheap though. Also it's a SATA SSD not a PCIe SSD as the title and description indicate. Having said all that, it does work after I swapped the battery so there's that. Would give more stars if the description was accurate and actually renewed. Would give fewer stars if the cost were higher, it's a compromise I suppose.
