Considerations for the Battery Pack and Memory
Battery Consideration
You cannot use the battery pack of the ThinkPad 380, 380D,
385D, 380E, 380ED, or 385ED computer.
You cannot use the battery pack with a non-Intel Pentium II
model of the ThinkPad 380XD, or 385XD computer.
You cannot use the ThinkPad 380/385 battery option
(part number 73H9797) for your computer.
Memory Consideration
The Intel Pentium II model of the ThinkPad 380XD or 385XD
computer supports the 60-ns extended data output dynamic random
access memory (EDO DRAM) card only. It does not support the
70-ns EDO DRAM card or the synchronous dynamic random access
memory (SDRAM) card.
Consideration for Using the Power Management Modes
At the time of purchase, your computer is set to autostart the
CD-ROM drive. Windows 95 periodically accesses the CD-ROM
drive to start programs on a CD-ROM.
Consider the following:
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.
The battery operating time might be short, even if you are not
using the CD-ROM drive frequently.
To change the properties of the CD-ROM drive, do the following:
1 Click on Start and move the cursor to Settings and Control
Panel. Then click on Control Panel.
2 Double-click on System.
3 Click on the Device Manager tab and double-click on
CD-ROM.

4 Click on the CD-ROM drive name under the CD-ROM; then
click on Properties.
5 Click on the Settings tab and remove the check mark from the
Auto insert notification check box in Options by clicking on
it.
6 Click on OK, and restart the computer.
