=== IBM UltraBay ===

{{NOTE|The IdeaPad Y400/Y500/Y410p/Y510p's Ultrabay is different from the Ultrabays used in ThinkPads. One notable difference is the inclusion of a TE Connectivity 2199022-1 connector (a proprietary implementation of MXM 3.0), which does not exist in all Ultrabay types used in ThinkPads. Therefore, Ultrabay GPUs produced for the aforementioned IdeaPads will NOT function in the ThinkPads' Ultrabays as they lack this connector.}}

UltraBay is IBM's name for the swapable drive slot. Introduced back in the times of the 770 Thinkpads, this technology has gone through redesigns with almost every new generation of Thinkpad models, possibly leading to some confusion that is hopefully cleared up here. The following table gives an overview of the different UltraBay types, in which models they occurred and what drives are available for them.

Note that the optical drive bay in G series Thinkpads is not an UltraBay in that the drives are fixed and not removable.

Ultrabay was IBM's, now Lenovo's name for the swappable bay. With IBM's definition{{footnote|2}}: <blockquote>"The ThinkPad UltraBay{{footnote|1}}, also standard with the system, is an intelligent bay that switches its pin-out signals to allow the installation of standard and optional features in what would normally be just the floppy disk drive bay."</blockquote> First introduced in the {{360}} and the {{750}}, this technology has gone through several redesigns with almost every new generation of models, possibly leading to some confusion that is hopefully cleared up here. The following table gives an overview of the different Ultrabay types, in which models they came from and what devices are available for them.

On the media side different UltraBays relate to the form factor of the drives they accept, e.g early A, T and X series models can accept UltraBay devices up to 12.5mm in thickness, whereas current T and X series machines are limited to devices no more than 9.5mm thick.

=== Overview ===
 +
Over the course of time, a number of different form factors have been used for the Ultrabay. They are generally not cross-compatible, but there are some exceptions to that (see below for more details). Current ThinkPads no longer use the Ultrabay, due to severe space constraints. Only a few models do feature the Ultrabay nowadays, but they are unfortunately crippled in such a way that they no longer support Ultrabay batteries and/or hot-swapping.
 +
 +
Keep in mind that not all Ultrabays are made equal, as some lack an eject mechanism and/or battery terminals that are needed to charge and discharge an Ultrabay battery. Some Ultrabays might also not support hot and/or warm swapping, even if they are capable of doing so in a different model (e.g. a high-end model supports hot, warm, and cold swapping, but the other lower-end model supports only cold swapping despite having the same Ultrabay type). These crippled Ultrabay variants are generally found on the low-end models, although they can also be rarely found on high-end models.
 +
 +
=== Linux support ===
 +
The pinout switching is performed by the BIOS and embedded controller, so that it is completely transparent to the operating system.
 +
* Floppy drives are supported by the standard floppy driver.
 +
* ZIP drive support is possible through the <tt>ide-disk</tt> driver.
 +
* IDE hard disks and optical drives are supported by the <tt>ata_piix</tt> or older <tt>ide-disk</tt> driver in the linux kernel.
 +
* Batteries are automatically handled by the hardware, but can be controlled further by using [[tp_smapi]].
 +
* Ultrabay Plus devices should be handled by the USB subsystem, but if the actual devices are is not known.

UltraBay drives
NOTE!
The IdeaPad Y400/Y500/Y410p/Y510p's Ultrabay is different from the Ultrabays used in ThinkPads. One notable difference is the inclusion of a TE Connectivity 2199022-1 connector (a proprietary implementation of MXM 3.0), which does not exist in all Ultrabay types used in ThinkPads. Therefore, Ultrabay GPUs produced for the aforementioned IdeaPads will NOT function in the ThinkPads' Ultrabays as they lack this connector.

Ultrabay

Ultrabay was IBM's, now Lenovo's name for the swappable bay. With IBM's definition2:

"The ThinkPad UltraBay1, also standard with the system, is an intelligent bay that switches its pin-out signals to allow the installation of standard and optional features in what would normally be just the floppy disk drive bay."

First introduced in the 360 and the 750, this technology has gone through several redesigns with almost every new generation of models, possibly leading to some confusion that is hopefully cleared up here. The following table gives an overview of the different Ultrabay types, in which models they came from and what devices are available for them.

Overview

Over the course of time, a number of different form factors have been used for the Ultrabay. They are generally not cross-compatible, but there are some exceptions to that (see below for more details). Current ThinkPads no longer use the Ultrabay, due to severe space constraints. Only a few models do feature the Ultrabay nowadays, but they are unfortunately crippled in such a way that they no longer support Ultrabay batteries and/or hot-swapping.

Keep in mind that not all Ultrabays are made equal, as some lack an eject mechanism and/or battery terminals that are needed to charge and discharge an Ultrabay battery. Some Ultrabays might also not support hot and/or warm swapping, even if they are capable of doing so in a different model (e.g. a high-end model supports hot, warm, and cold swapping, but the other lower-end model supports only cold swapping despite having the same Ultrabay type). These crippled Ultrabay variants are generally found on the low-end models, although they can also be rarely found on high-end models.

Linux support

The pinout switching is performed by the BIOS and embedded controller, so that it is completely transparent to the operating system.

  • Floppy drives are supported by the standard floppy driver.
  • ZIP drive support is possible through the ide-disk driver.
  • IDE hard disks and optical drives are supported by the ata_piix or older ide-disk driver in the linux kernel.
  • Batteries are automatically handled by the hardware, but can be controlled further by using tp_smapi.
  • Ultrabay Plus devices should be handled by the USB subsystem, but if the actual devices are is not known.
