HP OmniBook 4150 Release Notes page 7

In Windows 95, to avoid this problem with an external video adapter in the F1744A docking system:
* Set the Primary Video Adapter BIOS setup option to Auto so that the BIOS uses the external video
adapter on boot.
* Shut down your system from the Start, Shutdown menu before docking or undocking.
* Avoid Suspend to RAM while docked. To avoid Suspend to RAM:
- Do not push the blue power button.
- Do not press Fn+R on the keyboard.
- Leave Time-out on AC disabled in the BIOS Setup.
In Windows 98, to avoid this problem with an external video adapter in the docking system, set the Primary
Video Adapter BIOS setup option to Internal so that the BIOS uses the internal video adapter and leaves the
external video adapter for use by Windows 98 as a second video adapter. With this setting in Windows 98,
there are no restrictions to suspending the OmniBook, or docking or undocking the OmniBook while it is
turned on.
Windows NT 4.0
Restoring Operation under Windows NT
For Windows NT, if you install new services, hardware devices, or applications, you must reinstall the
Service Pack from the Recovery CD— see the topic farther below. This ensures that the Service Pack
components and other related components work properly. It will not write over any applications, settings, or
drivers you have installed.
For example, if you install Windows network support, you should reinstall the Service Pack so that other
components work properly.
Suspend Mode and the F1477A Docking System
The OmniBook may lock up if the OmniBook is suspended while docked to the F1477A docking system.
This is true even if the Phoenix APM driver is loaded. To avoid suspending:
* Do not push the blue power button.
* Do not press Fn+R on the keyboard.
* Leave Time-out on AC disabled in the BIOS Setup.
Using PC Cards
Use of some point-enabled cards and possibly other cards may prevent the system from hibernating when
battery power is low. Instead, the batteries can drain to the point of a nonrecoverable shutdown (data is
lost). To prevent this from happening when using these cards, do not leave the system unattended when the
batteries may drain to this low level. Instead, either connect a charger or power the system off. If APM is
installed on the OmniBook, the system will warn about low battery conditions. You should save any data at
this time.
Using multiple PC Cards configured with Auto configuration may cause IRQ conflicts. If this occurs,
configure the PC Cards manually when more than one is installed. When installing an ATA disk, run
winmsd.exe in \winnt\system32\ and click the Resources tab to find an unused IRQ (not displayed in the
