I had purchased an A/C wall adapter to recharge the battery for my sister's phone. The first time I used it, it worked great. The battery recharged perfectly. However the next time I tried, nothing happened. The battery doesn't charge at all and the phone is completely flat. I'm not sure what to do. Please help.

If you use a recharger other than the original, make sure that the voltage and polarity of unit is the same to one being replaced. Try to use one with a similar amperage as the original. Look for amperage rating of your batteries and then divide that by the amperage out on your charger to determine a safe charge time since you do not know if the replacement charger has an auto shut off - u do not want to overcharge the batteries and damage them.
If the cell phone battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.
you can use the computer to charge it via the USB, they do make house adapters that plug into the wall, very cheap to buy, and leaving it plugged in when not in use greatly extends the battery life. Go to ebay to get the house charger
Solution: As digital cameras become more advanced and include more features, the power needed to keep them functioning has also increased. That means that typical alkaline batteries likely won’t do more than power your camera for a few shots before running out of juice. Sometimes, your digital camera may not power on at all if the inserted alkaline batteries aren’t fully charged or powerful enough. Rather than carry along dozens of alkaline batteries for a single photo shoot, you can save money by purchasing rechargeable NiMH (nickel-metal hydride) batteries. Rechargeable batteries can be purchased with a charger that you plug into a wall outlet, and they fully charge in one to five hours depending on the charger and the type of batteries you’re using.
If you’re already using rechargeable batteries but are experiencing short battery life with your digital camera, it’s likely time to replace your rechargeable batteries with new ones. Depending on the number of charging cycles you perform (how many times you discharge and recharge your batteries), rechargeable batteries typically last for two to three years before they no longer hold a full charge. You may also ensure that you’re charging your rechargeable batteries directly before use. As batteries sit unused for extended periods of time, they automatically lose some of their charge.
There are many ways you can conserve battery life while using your digital camera, too. For starters, if your camera has a viewfinder in addition to an LCD, use the viewfinder to frame your shots and turn the LCD off because LCDs draw a lot of power. If you prefer to use the LCD, you can still conserve battery life if you refrain from looking at each picture on the screen after you take it.
Your LXT350 is equipped for using an optional rechargeable NiMH battery pack which can be recharged by inserting the AC adapter into the radio charge jack, or with the optional desktop charger.
I would make sure the radio is off, then insert the charger. Charge only for the prescribed time (no more/no less) and remove from the charger.
Charge time is initially 24 hours. Charge time is about 12 hours thereafter. For maximum battery life, it is recommend charging the battery pack when the low battery icon comes on. Remove the radios from the charger when the charge time expires.
"Removable drive" sounds like it got set back to MTC mode (USB mode in sansa settings menu). Needs to be in MTP mode to really be of any use.
I have the e280 and it recharges fine when it's hooked up to my PC. It might be the battery, the connection, or the player.
Also, it has to be a "high power" USB port on your PC (whatever that is). ie: If you're on a really old PC, there might not be enough juice getting through to the player. But if the rechargers don't work either.....
