To install APM (Advanced Power Management) support
Hewlett-Packard highly recommends that you install this software for proper operation of
your notebook running Windows NT 4.0.
If you have installed retail Windows you need to install the APM driver. The driver is
contained in the \HP\DRIVERS\APM subdirectory on the Recovery CD.
To install or upgrade the APM driver:
1. Run SETUP.EXE from the driver directory on your Recovery CD
(\HP\DRIVERS\APM).
2. Click the graphic to begin install.
3. Follow the onscreen directions to complete installation.
Upon successful completion you will be asked to reboot your computer, choose Do Not
Restart. If you installed this software package you should also disable CD-ROM Auto
Detect to ensure proper operation of the APM features.
To disable automatic CD-ROM detection
Windows NT 4.0 will automatically detect and respond when you insert a CD. However,
this prevents the HP notebook from automatically turning off after a period of inactivity
if the CD-ROM drive is present. To disable this feature:
1. From the Start menu, click Run.
2. Enter REGEDT32 then click OK.
3. Select the HKEY_LOCAL_MACHINE window and go to
SYSTEM\CURRENTCONTROLSET\SERVICES\CDROM.
4. Double-click the Autorun key.
5. Enter 0 and click OK.
6. Close the Registry Editor and restart Windows NT 4.0.
