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

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.

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.
