Hints, Tips and Limitations

This section provides hints, tips, and limitations.

	For Windows 98 and Windows 95: If you are using the Intel USB camera and the system resumes from suspend mode, the USB camera is disabled. To enable it, unplug it and plug it in again. Your computer might not enter suspend mode or hibernation mode after the end of a timeout period that was specified in the ThinkPad Configuration program because of the CD-ROM drive property settings. If you want to use suspend mode and hibernation mode, change the properties of the CD-ROM drive as follows: Click on Start. Move the cursor to Settings and click on Control Panel. Double-click on System. Click on the Device Manager tab and double-click on CDROM. Click on the CD-ROM drive name under CDROM; then click on the Properties button. Click on Settings tab and remove the check mark from the Auto insert notification check box in Option by clicking on it. Click on OK, and restart the computer. To use the scrolling and magnifying glass functions, you must disconnect any external mouse and enable the internal TrackPoint.
	For OS/2 Warp: HPFS/NTFS file-based hibernation is not supported. If you receive incoming faxes or mail under OS/2, you must set the modem settings in the fax application to one of the following: Hardware FIFO enabled Hardware Flow Control on UART 16550A modem In OS/2 FaxWorks for example, select Utilites, Settings, Modem Type, and H/W FIFO (16650A). If you do not set your modem to one of these settings, you will not be able to receive an incoming fax or an incoming call in suspend mode.
	For Windows NT: HPFS/NTFS file-based hibernation is not supported. For more information, refer to the following Web site: http://www.pc.ibm.com/thinkpad

Using a PC Card with the Port Replicator

In the Windows 95, Windows NT, Windows 3.11 or DOS environment, you need to install the PC Card support software after docking your computer to the port replicator. If you have already installed the PC Card support software, uninstall it and then reinstall it after you dock your computer to the replicator.

USB Connector Considerations

If your computer tries to enter suspend mode and the request is rejected, the device in the USB connector might be disabled. If this occurs, do a hot-unplug and -plug operation for the USB device.

Using a Second CardBus Card

If a CardBus Card is already configured in your computer or in the port replicator, you must configure the second CardBus manually by using the Device Manager. To get to the Device Manager, double-click on the System icon in the Control Panel.

Using an External Condenser Microphone

The microphone-in jack supports a self-battery-powered condenser microphone which might need a battery. See the instructions which come with the microphone.
