 ===== Questions and Answers =====
+**Q: What is the PRN-A-B Switch on the side?**\\
+**A:** Toshiba offered an external 360Kb disk drive as an option. This plugs in to the parallel port connector but is not a parallel device. Setting the switch to PRN enables the printer port, setting it to A tells the machine there is an external disk drive and you want it to be A drive. Setting it to B tells the machine there is an external disk drive and you want it to be B drive. Setting it to A would allow you to boot 360Kb boot disks.
+Unless you have the Toshiba external floppy – always set this to PRN. ((Source: http://baudband.net/?page_id=88))
 **Q: My computer gives me a configuration error when I turn it on**\\
 **A:** If the CMOS battery is empty, you will be prompted with the following error when you power on the machine.

 **Q: I am still unable to access the BIOS.**\\
 **A:** When the computer BIOS battery runs empty, it will clear all BIOS settings and will prompt you to review the system settings on power-up. This may be used to your advantage to get into BIOS. To force this behavior, disconnect the clock battery entirely. Wait for a few minutes and power up the computer again. The computer will ask the user to review the default settings.
-**Q: My computer does not hold settings or time**\\
-**A:** You probably have an empty BIOS battery. The battery holds volatile information in a CMOS chip like information about your BIOS settings and system time. When the battery runs out, the information will be lost. You can still use your computer by going into BIOS settings and re-saving the defaults (see above).

 ===== Troubleshooting =====
 **SYMPTOM: The computer turns on, power LED lights up, but I have no picture or a noisy picture**\\
-**SOLUTION:** This could be caused by many things, but the most common issue is that the laptop lid open/close switch is just stuck in the on position. The switch, which is located under the cover, next to the floppy drive uses a rather low-quality plastic piece that latched with the screen hinge and is designed to detect when the lid is closed, and will cut the power to the display accordingly. It engages whenever the lid is closed, and since it is near the power supply, a plastic piece inside the switch may slowly deform over time and may get stuck inside the switch. The symptom you will see is a screen that will never seem to turn on when you open the lid, or will have a noisy picture, due to the switch stuck half-on. If you cannot repair the switch manually, the easiest workaround is to just disable it by removing the plastic piece entirely. This will make the screen then stay on regardless if the screen lid is open. The gallery section on the T3200SX page may be helpful to identify the switch.
