The '''Digital HiNote Ultra''' is a thin notebook computer that Digital Equipment Corporation introduced in November 1994, alongside the HiNote VP, as the first of its HiNote range.<ref name="wp" /> Its lithium-ion battery pack latches on to the back of the case, and its 3.5-inch diskette drive is a separate Floppy Dock that screws on underneath.<ref name="wp" /><ref name="ug5" /> The later HiNote Ultra II and HiNote Ultra 2000 are different, Pentium-based machines.<ref name="wp" />

== Hardware ==
DEC's user's guide gives the specification as an Intel 486SX, DX2 or DX4 with 8 KB of internal cache, an 8.33 MHz ISA bus, a 256 KB flash BIOS, and 512 KB of video memory on the PC-70 and PC-71 or 1 MB on the other models.<ref name="uga" /> The passive-matrix and mono machines have 4 MB on the main board and the TFT machines 8 MB; one optional 4, 8 or 16 MB module fits in a compartment underneath.<ref name="uga" /><ref name="ug7" /> There are two PCMCIA slots taking two Type I or II cards or one Type III card, at 3.3 V or 5 V, and most models have 16-bit Sound Blaster-compatible audio on an ESS chip; the guide also covers an infrared port.<ref name="ug1" /><ref name="ug6" /> The pointing device is a trackball in front of the keyboard.<ref name="ug6" />

The battery is a 7.2 V, 3300 mAh lithium-ion pack (DEC part FR-PCP8H-AB) that DEC rated for about 3½ hours at full power.<ref name="uga4" /><ref name="readme" /><ref name="ug3" /> The clock is backed by a separate CR1220 lithium coin cell; the guide specifies a Sanyo part only.<ref name="ugw" /> The AC adapter delivers 11 V at 2.4 A from 90–135 V or 180–264 V.<ref name="uga3" />

== Known faults ==
* Battery pack not recognised. A pack left to run completely flat, in storage or in suspend mode, trips its protection circuit and is no longer seen by the computer: no charge light and no gauge. Packs of revision 36-44194-01 B01 can be brought back with Digital's REVIVE.COM utility. See [[HiNote Ultra Battery Service]].<ref name="readme" />
* Data lost in suspend. Suspend holds memory for up to two weeks from a full battery, and pressing the reset button while suspended loses it.<ref name="ug3" /><ref name="ug1r" />
