PC Card - A credit card-sized device that can be used for a variety of functions, including a flash memory card, network card, modem, or hard drive.
Type I - Primarily used for adding RAM to a laptop PC.
Type II - Similar to Type I card; featuring a 16-bit or 32-it interface, using two rows of pins.
Type III - Uses four rows of pins with a 10.5 mm thickness, allowing the accommodation of larger connectors for peripherals. Since the removal of legacy ports from most modern laptops, type III ports are typically no longer used.
CardBus Card - A 32-bit PC Card with bus mastering, which allows a controller on the bus to talk to other devices or memory without going through the CPU.
ExpressCard - Replaced CardBus technology, with an increase in bandwidth due to the fact that it establishes a direct connection to the system bus.
Before removing a storage PC Card, such as a hard disk PC Card, a Flash memory PC Card, or a SRAM PC Card, from a PC Card slot, you must stop the PC Card. Otherwise, data on the PC Card might be corrupted or lost.
Do not remove a PC Card or an ExpressCard while the computer is in standby mode or hibernation mode. If you do, the system will not respond when you try to resume operation.
You can stop the PC Card with the PC Card support software and remove it, without turning off the computer.
For Microsoft Windows XP users: Click the Safely Remove Hardware icon in the task bar, and then stop the card.
For Windows 2000 users: Click the Unplug or Eject Hardware icon in the task bar, and then stop the card.
This illustration is demonstrating how to install a card on a Z61m. The location of the PC card slot will vary depending on the type of system.
To remove the card, do the following:
Press the card eject button to pop out the button.
Then press it again until the card pops out.
Remove the card and store it safely for future use.
Note: If you do not remove the card after selecting the Safely Remove Hardware icon to stop the function of the drive, the card can no longer be accessed. To access the card, you must remove it once, then insert it again.
The PC Card support software enables you to use a PC Card as soon as you insert it into the computer.
For Windows XP or Windows 2000, no extra software is needed; the PC Card support function is included in the operating system.
When you insert the PC Card into your system:
The PC Card support software detects the card, reads the information about it, and searches for the device driver needed.
The device driver requests the PC Card support software to allocate such system resources as memory space, I/O port, and IRQ. If these resources are available, the support software recognizes the PC Card, and you can use it.
If there is a resource conflict, you may need to do follow one of the following:
Change the resource assignment: You can allocate the available resources by using the operating system or the PC Card support software function.
Change the system configuration: You can change the system configuration with your operating system or with the ThinkPad Configuration Program.
Depending on the function of the PC Card, changing the power mode may cause your system not to respond. PC Card support software prevents this occurrence through special handling during transition between power states.
