If a USB Device Is Disabled:
If your computer tries to enter
suspend mode and the request is rejected, the device in the USB
port might be disabled. If this occurs, do a hot-unplug and -plug
operation for the USB device.
Hot Plugging or Unplugging a PCMCIA Card
After your computer returns from standby mode to normal operation,
you cannot perform hot-plug and -unplug operations for certain
Network PCMCIA Cards in the docking station slots. Reboot the
system to solve the problem.
Using a Second CardBus Card
If a CardBus Card is already configured in your computer or in the
docking station (SelectaDock III or PC Card Enabler), you must
configure the second CardBus manually by using the Device
Manager. To get to the Device Manager, click on the System icon
in the Control Panel.
Increasing Memory Capacity
The ThinkPad 770E or 770ED computer supports SDRAM only. It
does not support the EDO DRAM Card. Installing a DIMM (dual
inline memory module) that is not supported by the ThinkPad 770E
or 770ED computer might cause a problem. You can purchase the
SDRAM option from your IBM authorized reseller or IBM marketing
representative.
Using the COM Port in OS/2
If the COM port does not work even after you set up this port
correctly using the ThinkPad Configuration program, do the following:
1
Go to System Setup.
2
Select Hardware Manager.
3
Select Folder from the menu.
4
Select Properties.
5
From the default pull-down menu, select NO HARDWARE
DETECTION, or change the setting if it is already selected.
