Serial Ultrabay Slim HDD Adapter IV (4XH0L67917)

This is a HDD adapter that slides into a Serial Ultrabay Slim.


  • One SATA slot for a 2.5-inch, 7 or 9.5-millimeter HDD/SSD/SSHD
  • Weight: 88 grams or 0.19 pounds


  1. This FRU does not contain the required MicroSATA-to-SATA adapter, as it's only a housing shell which holds the drive. To 'fix' this issue, you need to get two M2.5 (length unknown) screws and a board identified as the 'BP700 NS-A447'. The BP700 NS-A447 board contains the said adapter to connect the 2.5-inch storage drive to the MicroSATA connector.
  2. This FRU requires a 2.5-inch drive bracket to secure the drive, which can be found in the ThinkPad Mobile Workstation Storage Kit (FRU: 4XB0L63274).
