Troubleshooting Solving Basic Problems If the screen is difficult to read • Try adjusting the display—press the ∧ and ∨ buttons above the keyboard. Try holding FN and pressing one of the buttons. • If the OmniBook is cold, allow it to warm up. • Set the display resolution to its original setting: 800Ч600 (SVGA) and 256 colors, or set the lowest available setting. For Windows for Workgroups, use Display in OmniBook Tools. For Windows 95, use the Settings tab under Display in the Control Panel (under HP User Tools or under Settings). If an external display won't turn on • If the external display is unrecognized by the OmniBook, the computer will not send it video signals.
However, you can force the computer to send these signals anyway. Open the OmniBook External Devices screen (Start, Settings, Control Panel, then OmniBook External Devices). Check the box that reads Force video signal to external display . • Check that Cache is enabled (in the System Configuration Utility, open the System menu and check Enable Cache). • You might need to install more RAM. The memory-expansion boards are HP part numbers F1167A (8 MB), F1168A (16 MB), and F1169A (32 MB). If the computer seems slow If the infrared connection does not work • Try re-aligning the two devices to align their infrared ports. Make sure the two devices are no more than 1 meter apart.
• Check the settings in your communications software and in the OmniBook's IR Monitor. IrDA must be enabled. If you cannot install Windows NT 3.51 • In the System Configuration Utility, under the System menu, Boot Devices..., enable the checkbox Force PCI Bridge Configuration. 2-9
