Mp3 will not stay powered on

Yes,
you will have power through the usb port, so leave it plugged in.
Even when it is shut down it can drain batteries.

try removing the battery and removing the adaptor press and hold down the power button for 5-10 seconds then let got this will power drain your system board noy turn the system on using the battery only without any adaptors to charge or power the system, try turning the system on if the system turnes on leave it turned on for a couple of hours then conenct your sysem adaptor monitor if the battery light and the battery indicator on the lower right of the screen in windows woll indicate that the system is chargin if it is then I believe everything should be fine the blue indicator is for your system if it is blue then your system is turned on and has power if it turned orange and blnking then the battery will be more likely be almost out of juice or may need charging.

well i think your mp3 has got some sort of a file containing a virus so try format it it should help

The problem lies with the power supply system either in the power adopter or inside the laptop. When AC power is plugged in, the system shows that the battery is being charged (Yellow Light Indicator switches ON) but practically niether the battery is usually being charged nor the computer is being run by the AC power. Its a little bit of energy left in the battery that keeps running you computer for some time and as soon as the battery is discharged the note book shuts down by itself.
However, the Taskbar battery indicator gives the correct picture of battery charge and the charging process. Better rely on that.
Its a hardware problem pertaining to power supply and charging system and doesn't have to do any thing with Mother board, RAM, Hard disks or other hardware installed in the PC.
Do tell the above details to a repair workshop man to rectify the problem.... Best of Luch

Hey,
Try these steps, if they aren't of any help, you may have to have the vendor replace your mp3 player.
SOLUTION 1 - Reset the device. 
1. Press and hold the Power/Menu button for approximately 20 seconds. 
2. Release the Power/Menu button. 
3. Press the Power/Menu button again to turn on the player. 


SOLUTION 2 - Power cycle the device. 

STEP 1 - Remove the battery 

STEP 2 - Power cycle the player 
1. Connect the device to the PC. 
2. Leave the device connected for about 2 minutes. 

STEP 3 - Turn on the device 
1. Disconnect the player from the PC. 
2. Insert a fresh AAA battery into the player. 
3. Turn on the player. 

Change your AC charger.
It's NOT charging "When the laptop is plugged into the AC, the power meter in windows tells me that the power source is still batteries, and the battery level drops by about 1% every few hours"
That's the reason why: "battery has completely died"
If you do not change it you'll continue to "still it gives me the same low battery indication and will not turn on. "

Reset the battery.....remove battery from system...boot while your adapter is plugged on....shut down..reinstall the battery......

if this doesn't help..

go to Control Panel>>>>>>Power Options and view setting ..........what does the system do after being switched off options



keep me posted
Cheers

Have you tried removing and replacing your battery? What about the connections and cord, are they damaged at all?

Did you use rechargeable NiMH battery try this. One's again its make same problem means. Check weather their is an DC plugin if it their means just buy the adapter regarding to it power supply...
