SYMPTOMS
When you click the Power icon in Windows 95 Control Panel on a NEC Versa
computer, you may receive the following error message:
Rundll32 Caused a General Protection Fault in Apmext.dll
CAUSE
NEC includes a custom power management dynamic-link library (dll) file
named Apmext.dll with Windows 3.x on some of its Versa laptops. This dll
is hard-coded to the Microsoft-supplied Windows 3.x Power applet in Control
Panel. The Apmext.dll file is not compatible with Windows 95.
RESOLUTION
To work around this behavior, remove the following line from the
[Power.drv] section of the System.ini file:
OptionsDll=apmext.dll
MORE INFORMATION
The Apmext.dll file tries to dynamically add a second battery meter status
bar to the Power applet display in Control Panel. The Windows 95 Power
applet is different from the Windows 3.x version, causing the Apmext.dll
file to cause a general protection fault when it tries to modify the
dialog.
