Using a PC Card

Updates and Corrections

The Diskette Factory program does support Windows 98.

You can use a PC Card without PC Card support software
(CardWizard). For details on how to use a PC Card, see the manual
for Windows 98.

Your ThinkPad computer does not include the PC Card support
software (CardWizard), so references to it in the

User's Reference

do not apply to your computer.

ThinkPad 600

In addition, if you are communicating with a PC Card modem or
inserting a network PC Card in a PC Card slot, you should not put
your computer into suspend mode or hibernation mode, nor should
you click on Stand by in the “Shut Down Window” window.

If you want to put your computer into suspend mode, first stop
the PC Card in the “PC Card (PCMCIA) Properties” window as
follows:

1.

Click on Start, move the cursor to Settings, and click on
Control Panel.

2.

Double-click on PC Card (PCMCIA).

3.

From the list, select the card you are stopping.

4.

Click on the Stop button.

If you remove a communication PC Card from the PC Card slot and
then reinsert it later, it might not work correctly. You need to reboot
your computer.

Using Modem Features

For information about modem features in the
same description as Windows 95 applies to Windows 98.

Using Power Management

For information about power management, follow the same
instructions for Windows 98 as for Windows 95.

The word Stand by on the Windows 98 screen has a different
meaning from the word standby in the

Updates and Corrections

In addition, note the following:
Suppose you activate the alarm action as follows:

Notification: Display message
Power level: When the alarm goes off, the computer will Standby.

Now, if your computer goes into suspend or hibernation mode when
the battery is low before the alarm message appears, you will see
the message when the computer resumes. To resume normal
operation, press OK.

You can set the alarm action as follows:

1.

Start the ThinkPad Configuration program.

2.

Click on Power Management.

3.

Click on the Alarm tab.

4.

Put a check mark in the Low Battery Alarm check box, the
Critical Low Battery Alarm check box, or both.

5.

Set the percentage of the power level.

Using Windows 98

6.

Click on the Alarm Action... button. You can set the alarm
action in the next window.

Even if you don't set the low battery alarm, the charge indicator
will let you know that the battery is low, and then the ThinkPad
will automatically enter the power-saving mode. This default
low-battery behavior is independent of the operating system, so
the computer might behave differently from your setting if you set
the low battery alarm. The computer chooses appropriately
between your setting and the default setting.

In Windows 98, it takes longer to enter suspend mode and resume
normal operation than it does in Windows 95. This performance
difference is caused by Windows 98, not the ThinkPad features.
