IBM ThinkPad 600 User Manual

Problem Action
| The computer does not
| enter suspend mode as
| set by the timer under
| Windows 95 or Windows
| NT.
| For Windows 95:
| The Windows 95 generic CD-ROM driver accesses the internal CD-ROM drive
| every 3 seconds to check if a CD-ROM is inserted in the CD-ROM drive. This
| prevents your computer from entering suspend mode even after a timeout.
| To prevent this, do the following:
| 1. Double-click on My Computer, Control Panel, and System.
| 2. Click on the Device Manager tab.
| 3. Click on the + mark of CD-ROM.
| 4. Double-click on the CD-ROM drive name.
| 5. Click on the Setting tab.
| 6. Remove the check mark from Auto insertion notification.
| Windows 95 no longer detects the CD-ROM insertion automatically.
| For Windows NT:
| The computer does not enter suspend mode by the timer if you enable the
| CD-ROM AutoRun feature. To enable the Suspend Timer function in the
| registry, do the following:
| HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Serveces\Cdrom\
| Autorun: ×1 → Autorun:
