The ThinkPad 770Z is ACPI Ready. While ACPI shows a great deal of promise for the future, there are still numerous problems affecting operation of ACPI on ThinkPad and other notebook systems. Therefore, the system comes with Windows 98 running in APM mode. When the remaining issues with ACPI are resolved, an upgrade package will be made available on the IBM Web site. The upgrade package will contain the guide of update procedures in addition to device driver updates, and BIOS updates as necessary to make ACPI work reliably.
Many factors affect application performance.
The ThinkPad 770Z recognizes up to 320 MB of addressable memory with the new Mobile Pentium II processor at 366 MHz. Accessible capacity may vary. The V.90 modems are designed to be capable of receiving data at up to 56 Kbps from a compatible service provider, and transmitting data at up to 33.6 Kbps. Public networks currently limit maximum download speeds to about 53 Kbps. Up to 14.4 Kbps for facsimile and other telephony functions.
