1. Actual playback speed will vary and is often less than the maximum possible.
2. An optional 10.0 GB HDD is available.
3. MHz measures only processor internal clock speed, not application performance. Many factors affect application performance.
4. Pentium II processors have 256 KB onboard L2 cache; the Celeron processor has 128 KB onboard L2 cache.
5. Thin film transistor (TFT) is the technology of the display.
6. GB equals one billion bytes and MB equals one million bytes when referring to hard disk drives. Capacity available for end users may be less.
7. The V.90 modems are designed to be capable of receiving data at up to 56 Kbps from a K56Flex or V.90 service provider, and transmitting data at up 31.2 Kbps. Public networks currently limit maximum download speeds to about 53 Kbps. Actual speeds depend on many factors and are often less than the maximum possible. (for US, LA, CAN, EMEA only)

The ThinkPad 390E has powerful new processors with new technology L2 cache. The Intel Mobile Pentium II processors at 333 MHz or 300PE MHz have 256 KB full-speed onboard L2 cache. The Intel Mobile Celeron processor at 300 MHz has 128 KB full-speed onboard L2 cache. Onboard means it is not in the memory card but back with the chip. This eliminates the local bus and results in better performance.

Non-parity, 64-bit of SDRAM SO DIMM memory. Standard memory of 64 MB or 32 MB, depending on model, is expandable to a maximum of 256 MB with 32 MB, 64 MB, or 128 MB cards. An internal slot is available for one extra memory module for customers who require a memory upgrade.

The Type III slot can accommodate either two Type I, two Type II, or one Type III PC card. Both 16-bit and 32-bit cards are supported. Both PCMCIA slots contain a ZV port.

The auto configurator and memory device driver enable supported PCMCIA cards by sensing them automatically. (PCMCIA cards supported by the auto configurator and memory device driver are listed in the Sales Manual.)

The standard 6.4 GB, 4.3 GB, or 3.2 GB HDD can be expanded optionally with a 10.0 GB HDD. An optional 6.4 GB HDD is also available. These S.M.A.R.T. HDDs issue an alert if a failure is pending. The three-spindle design of the 1.44 MB FDD allows all the drive units, including the FDD, to be contained inside the ThinkPad 390E covers.

Software MPEG 1 support on Windows 98 systems provides multimedia viewing without such hardware prerequisites as ZV port cards. MPEG 1 decoders facilitate educational use for activities such as movies, teleconferencing, and games.
