General problems.

Notebook with Bluetooth won’t enter standby or hibernation.

Make sure correct drivers are installed. In Device Manager, double-click Infrared devices, then double-click IrDA Fast Infrared Port. On Advanced tab, click Infrared Transceiver A in Property window, then select IBM 31T1100 from pull-down menu.

Make sure the line between the two infrared ports is not blocked, ports face each other squarely and are no more than 1 meter apart. Sunlight, heat from nearby equipment, or other sources of infrared radiation can cause transmission errors.

Make sure only one application is using infrared port.

Remove any PC Cards from notebook (possible IRQ conflict).

For fast-IrDA, check for DMA conflict with ECP parallel port.

Check TCP/IP setup in Control Panel.

Check SSID and channel settings: click wireless link icon in taskbar and select Advanced Configuration.

Stop USB devices that may perform large data transfers, or adjust application settings to reduce transfer rate.

Make sure wireless PCA and antenna are installed properly.

Disable Bluetooth. If Bluetooth device is transmitting, notebook may not be able to enter standby or hibernation.
