No power when i switched it on and it is full charge

On Off switch is the slide button on the side The switch may be faulty. You don't normally need it switched on to use USB, as the computer is supplying the power. This says it needs to be on for charging, that is odd!

When connecting to the computer via USB, it WON'T be recognised as such, but it you open Windows File Explorer, you will see it as a Volume in the left hand side pane. Drag music to a folder and drop music in from there.

Plug in the cord with the switch off. If the battery is still good in the unit then it will take a full day to charge. If you charge it for a full day and you still have nothing the battery is bad. If this is a new unit, check to see if it is under warranty.

Remove the battery cover and remove battery for about 30 seconds. Then replace battery and power up your tablet and see if that does not reset it.

Well most likely, your batteries are weak. When the charger shuts off, the batteries have stopped taking charge, but they're not necessarily at full strength, especially if they've been sitting for a while without being charged. Connect the wires from the power switch together and try again. If it works replace the switch. If not, turn the motor shaft both ways. If it makes clunking noises, it's cooked. Otherwise you probably need batteries. Ive never seen a throttle or controller cause slow operation. And also always keep your tires pumped up.

Things to check: Drive/Free wheeling switch, brake release lever (this activates an internal micro-switch that enable power to the drive system, battery box connectors (condition of contacts - corroded, missing, loose. etc.); main control cable (corrosion. lose or missing pins, etc). If all these are OK, could be controller or drive control potentiometers (speed, forward, backward) on the handle-bar (tiller).
Good luck!

i think u should switch off your phone and it will charge smoothly till it full

Double check that the charge was enough. There is a pressure switch on the refrigerant line that is inline with the wire that powers the clutch for your compressor. You can check it with an ohm meter. Disconnect the two wires and check. If the system is charged properly, there should be full continuity across the pressure switch. You can check the clutch at the same point. Take the wire that goes from the switch to the clutch and supply battery power to it. It should click positively.

It is problem with your laptop's SMPS ie. Switched Mode Power Supply.

Due to which your laptop can't get regulated power supply neither from Power Cord nor from Battery.

Yes, your LED will show charging but its useless because your laptop's Mother Board Chip is not getting power.

So please ask some hardware engineer to replace it.

michelle,

not so familiar with this model but try this:

1) Plug your power adaptor to main unit
2) locate "power on" switch and change it to "off"

after doing this steps you will see a red light which means the unit is charging.

note: for some portable player once the charging is complete this red light changes color either orange or green which means the battery already full charge. but it is adviceable to charge battery for atleast 2hrs.

cheers,
