- Q: I just won a Hasee MJ 125 netbook and when I try to charge it, yellow light comes out instead of lavender light (that means it's charging). When I turned on the power, the laptop doesnt recognize the battery pack. I pulled the power cord out, the laptop turned off.How can I make the laptop recognize the battery pack? Please help. Thanks!
- remove the battery and put it back in
- Q: I foolishly burned out 2 green LEDs already since I provided too much voltage. The 2 green LEDs I need to light up have a forward voltage of 3.2 volts each. The battery pack has 3 AA rechargeable batteries, for a total of 3.6 V(1.2 V per battery). If I remove one battery, the LEDs won't light up at all. How can I reduce the voltage so it doesn't burn out my LEDs, do I need to use a resistor or can I use something else? If I need resistors, what kind of resistors should I use?
- Your LED needs a minimum of 3.2v to light up. That's why removing one battery fails to work. You're using two LEDs, so they're apparently in parallel. (In series, you'd need 6.4v to make them work.) In any case, it's not excessive voltage that's damaging the LEDs, but excessive current. You need a current-limiting resistor between the battery and the LEDs. Be careful, though. When the resistor limits the current, it will also drop the voltage that gets to the LEDs. So it takes a little math. If you were using a single LED, odds are that its maximum current rating is around 20ma. You're providing 3.6v, but only need 3.2v, so you can afford to drop 0.4v across the resistor. The same current that flows through the resistor will flow through the LED. So the resistor calculation is E/I, or 0.4v divided by .02a, for 20 ohms. Standard resistor values are 22 ohms, so that's good. Since you're using two LEDs in parallel, connect a 22 ohm resistor to each LED, then connect the LED/resistor combination in parallel.
- Q: Can your Xbox controller recharge from the xbox controller power cable if you put regular rechargeable AA batteries in a standard battery pack instead of buying the designated Xbox rechargeable battery pack? If it's possible, I thought it could be a way I could save money.
- you could just buy a battery recharger
- Q: I just bought the Rechargeable battery pack for xbox 360. I already had the Play and Charge Kit but it stopped working. I thought the the battery pack had died because it wouldn't charge. But when i plugged the charger into my xbox and into my controller, no light showed up. I don't know if the battery pack is already fully charged or if my charger is just screwed up.
- Its probably best. It may not last very long if you don't.
- Q: I was looking to getting a Nikon, but it says that the Nikon D3100 and D5000 both use battery packs, are they really worth the trouble? Will I not be able to use my own batteries if the pack happens to go dead?
- No worrie on that!! the sole element you like is a adapter which makes your potential suply in extreme high quality concern to Euroean suplies. verify you purchase an adapter which fits for the rustic you're traveling to. (united kingdom is diverse than Germany or Italy). on the airport you will get an multi adaptor for finished Europe (Atlanta Airport $25) Pertaining the Voltage you don?t would desire to care. Nikon aspects a unfold that suits to u . s . a . one hundred ten V and to Europe 230 V. get exhilaration out of your holiday to Europe. Regards from south west Germany

- Know the delay time to calculate the battery specifications: load * delay time H / (coefficient 10.6 * a group of battery section) = 28000 * 0.5 / 32 * 10.6 = 41AH calculated the battery capacity, find a similar battery can be, this Configuration with a group of 32 38AH battery delay of about 30 minutes
