For Windows 98 and Windows 95:

Hibernation is not supported if OS/2 Boot Manager is installed.

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:

  1. Click Start.
  2. Move the cursor to Settings and click Control Panel.
  3. Double-click System.
  4. Click the Device Manager tab and double-click CDROM.
  5. Click the CD-ROM drive name under CDROM; then click the Properties button.
  6. Click Settings tab and remove the check mark from the Auto insert notification check box in Option by clicking it.
  7. Click OK, and restart the computer.

To use the scrolling and magnifying glass functions, you must disconnect any PS/2 mouse and enable the internal TrackPoint.

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.

Using a PC Card with the Port Replicator

In the Windows NT, Windows 3.11 or DOS environment, you need to install the PC Card support software after docking your computer to the ThinkPad Port Replicator with Advanced Etherjet Feature. If you have already installed the PC Card support software, uninstall it and then reinstall it after you dock your computer to the replicator.

Using the Network Feature in the Port Replicator

When you dock your computer to the ThinkPad Port Replicator with Advanced Etherjet Feature, do as follows:

  1. Click Start.
  2. Move the cursor to Settings; then click Control Panel.
  3. Double-click System.
  4. Click the Device Manager tab.
  5. Expand the Network adapters item by clicking it.
  6. Double-click the Intel 8255X-based PCI Ethernet Adapter (10/100) item.
  7. Make sure the Exists in all hardware profiles item is unchecked.
  8. Click OK.
Note:You only need to do this procedure once.

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.
