of installed memory.
Your memory module is not
properly installed.
Remove and re-install your memory upgrade module.
See “Memory Upgrade
Module” on page 65.
You have a memory
failure.
Check for Power On Self Test (POST) messages.
USB Device Problems
Your notebook does not recognize
a USB device, or the device does
not seem to work properly.
The device is not properly
installed.
Remove and re-install the device.
See “Device Ports” on page 45.
The device may have been
installed while an application
was running, so your note-
book is not aware of its instal-
lation.
Close the application and restart your notebook.
Your device may not have the
correct software driver active.
See your software documentation and activate the correct driver.
ExpressCard Problems
A card inserted in the ExpressCard
slot does not work or is locking up
the system.
The card is not properly
installed.
Remove and re-install the card.
See “Using ExpressCards™” on page 60.
You have wrong I/O address
selected for your card.
See your ExpressCard documentation to determine the required I/O address.
Change the settings in Device Manager.
The card may have been
installed while an application
was running, so the notebook
is not aware of its installation.
Close the application and restart your notebook.
Your software may not have
correct software driver active.
See your software documentation and activate the correct driver.
Your card and another device
are assigned the same I/O
address.
Check all I/O addresses located within the Device Manager and any other installed
hardware or software to make sure there are no duplications.
