Check that your power adapter is working fine it may be that the power cable is broken somewhere between the adapter and the laptop. You could try another charger / adapter.

without the proper charger you could damaged the phoneand or the battery, attempting to charge it with out the proper regulated charger is not advised. you can find an aftermarket charger for alot less money than it would cost you to replace the phone because of damage. incidently because most batteries are either nickel-cadium or lithium ion you could potentially explode a battery by not using a proper charger this would result in a painful injury.

ok i have the same amp and 1 2ohm dvc sub and was woundering the same thing but from futher research and askin sum xsperts. What i found out is that it is only one channel and even tho there are 2 (+) and 2(-) they actually connect inside the amp makein it one . so if u wanted to wire sumthing parralel u wouldnt have to hook wires from one coil to the other on the speaker , u can just hook it up to the amp. so basically both +'s and negatives on the amp are actually one within it so all the power if you only use one set of them and if u wanna add more subs its just easier to add to the amp by using the xtras .

Nothing needs to be removed. You have to move the swiring around just a little. Magnetize a 11 mmm socket and set it on using a 1/4 inch ratchet, with a short extension. Loosen the nut and pull it out. Its a bi&^%$%^ to get out but it will come right out and then pull the battery out the side. make note on how the cables are set on the battery so you put it back in the proper way and the battery cables dont touch anything when you put them back in the holder. Hope this helps. TOM

Use a wrench to remove the negative and positive battery cables: They are clearly labeled "+" and "-." Always remove the negative cable first, as this isolates the power to the metal parts of your car. Tuck the cables away from the battery as you don't want them to accidentally touch a battery terminal when you're wiring your alternator.
Locate the alternator terminals. There are two: one marked "live," "pos" or "+" and the other marked "neg," "field" or "-."
Locate the two cables. The positive (red) cable goes to your battery via a wire loom or harness. The negative (black) cable attaches to a metal part of your car.
Check how the cables attach to the alternator terminals. Some connect using eyelets that hook over the terminal and tighten with a bolt; others connect by inserting the wire under the terminal and tightening a bolt.
Loosen the two bolts using a suitable-sized wrench or, if the cables connect using eyelets, remove the bolts.
Insert the exposed end of the negative (black) cable under the loosened bolt on the negative terminal of the alternator, then tighten the bolt. If the cable has an eyelet, hook it over the terminal and screw the bolt back in place and tighten using a wrench.
Insert the exposed end of the positive (red) cable under the loosened bolt on the positive terminal of the alternator, then tighten the bolt. If the cable has an eyelet, hook it over the terminal and screw the bolt back in place and tighten using a wrench.
Replace the positive battery cable on the positive battery terminal using a wrench. Replace the negative battery cable on the negative battery terminal.

Remove the 9-volt battery to be tested from the device it is powering.
Read the instructions of the testing device to ensure an understanding of how to connect the battery to the tester properly.
Attach the battery to the testing device according to the manufacturer's instructions, being careful to attach the positive terminal of the battery to the positive input of the testing device, which will be indicated by a "+" or "positive." Attach the negative terminal of the battery to the negative input of the testing device, which will be indicated by a "-" or "negative."
Read the display of the testing device to determine the status of the battery. If the voltage is low, replace the battery with a new one.
The electrical output of a 9-volt battery will decrease slowly until it reaches a level that is no longer adequate to power a 9-volt device. When the output of the battery decreases to 5.5 volts or less, the battery should be replaced as the power output has diminished to a point of imminent failure.
