To remove a PC card
Caution
Never remove an I/O card while an application is open that’s set up to use that
card. Exit the application first. If you remove the card, the application (or the
OmniBook) might behave unpredictably or stop responding until you restart
the OmniBook.
Never insert or remove a plug-in card while the PC card drive is actively
reading or writing data. Wait until the PC card drive is done. Otherwise, you
could lose data or the OmniBook could stop responding.
1. If necessary, rotate the ejector button so that it protrudes from the case.
2. Press the black ejector button until the card pops out, then pull out the card.
