Plug type and polarity (the plug that goes into the gadget, not the wall): Most adapters have two-conductor plugs, some have three. You can have an adapter with the right voltage and current, but if the plug's wrong, you're stuck. Polarity also varies among different models; some have a positive internal pin with a negative outside, some have it the other way around. A multi-use adapter allows you to switch polarity, so it will work with the widest range of equipment.
Unplugged
4. Toshiba pa3715u-1aca AC adapters consume current even when they're not powering anything. If you touch one that's plugged in, it will be warm. To save energy and money, unplug the adapter when it's not in use. If you are recharging your cell phone, note when it's full, so you don't waste anymore power than necessary.
Testing
5. If you have a piece of equipment that's working poorly, the cause might be its Toshiba AC adapter. You can check the voltage and polarity easily with a handheld multimeter. If you're lucky enough to have an oscilloscope, use it to test the adapter. Look for excessive ripple (bad capacitors) or lack of DC offset (bad diodes). If you find anything amiss with the adapter, simply replace it with an equivalent.
