Saving Battery Power
battery operating time to be shorter than the time publicly
stated.
Do not remove memory when the computer is in
hibernation mode. If you do, the computer resumes from
hibernation mode without recognizing the changed
memory size. To ensure that the computer recognizes the
correct memory size, shut down; then restart your
operating system.
If the computer is powered with battery power, it turns
power off to the PC Card when entering hibernation mode.
When resuming normal operation, if the PC Card or
computer does not operate, restart the application or
computer.
If the computer is powered with AC power, it does not
enter hibernation mode if it is using one of the following
IBM PC Cards:
– IBM 28.8/14.4 Data/FAX Modem
– IBM PCMCIA Data/FAX Modem
– IBM High Speed PCMCIA Data/FAX Modem
– IBM 3270 Emulation Credit Card Adapter
– IBM Token-Ring 16/4 Credit Card Adapter
– IBM Credit Card Adapter for Ethernet
– IBM 5250 Emulation Credit Card Adapter
– IBM Microelectronics 2.4/9.6 Data/FAX Modem
– IBM Microelectronics 14.4/14.4 Data/FAX Modem
– IBM Wireless Modem for ARDIS
– IBM Wireless Modem for Mobitex
– IBM Wireless Modem for Cellular/CDPD
This prevents possible problems from occurring with
communication application programs after the computer
returns to normal operation.
Note:
If the communication links are still not reestablished, remove and then
reinstall the PC Card before restarting the system or application program.
