GPX ML648B Will not hold charge

The GPX unit will work when plugged into the USB port, but when I unplug it it immediately shows a battery with an "x" through it and says "bye-bye." This unit is only 3 months old and hardly used. Is there a way to replace the battery? Or what can be done? Thanks for the help!

The Player gets it's charge from the USB port. I would recommend plugging your Player in and leave your computer on overnight.
If your player still does not retain a charge, I would contact the manufacturer.

Will not hold a charge

Check when the adapter is plugged if the battery is charging correctly and if it charges to the full. Leave it one for about a day and check if charged , Now check the time it works ,till you fully discharge and repeat the process.
But if the battery is not holding charge, try for final with your carr charger or one from a friend beffroe wee can fully confirm the battery is faulty . Replace ONLY with the original from the dealer with the warrranty.

My GPX ML648S MP3 player turned off while charging and won't turn back on. What do I do?

are you charging with your computer through the USB cord or did you get an adapter to charge via an outlet?
If charging with your computer, it could be a bad USB port, try the ports in the back of the tower if your using the front and vice versa.
Is the device responsive otherwise? Can you load music and the like while the device is connected? If not your USB Cord could be faulty and need to be replaced.

If you are using a laptop keep in mind that sometimes the amount of voltage required for this device does not always reach the USB ports. Try disengaging the laptop battery for an hour and then reconnecting it.

Player does not charge from USB port

make sure no other devices are plugged into your computer at the time. Also try restarting the computer with the device still connected.

If operating on a laptop be aware that you may not be receiving enough voltage to your USB port to satisfy the MP3 player. Try disegaging the laptop batter for an hour and then reconnecting it.

I charged the gpx for 1 day straight and i un plugged it then it showed a battery with an x said bye bye and turned off.

I think it's safe to assume that either your batter is no good or your cable is no good. You can contact GPX and with proof of purchase you should be able to get it replaced. You can also just buy a new cord or borrow one from a friend if they have it. See if your cell phone charger will plug into the MP3 player as well.
also if you are charging from a laptop be sure that no other devices are plugged into the other USB ports. I hope this helps.

Cant get it to charge

I tried to reset and it didn't work, They way I figured out was to shut it off then plug the USB in. Then the screen shows up where it is sleeping, Then hit the power button one time and in the bottom left the USB light came on and in the top right you can see your battery taking charge. Hope this helps, It took me about three weeks to figure out

Having trouble synching with gpx ml638b...

If this problem occurs then your ML648B needs to be formatted.

1. Connect your ML648B to your computer with Windows XP or later.
2. By default your computer will recognize ML648B as GPX MTP Device. Press the POWER button from top of your ML648B, to change it to USB mode connection. You will also see USB on the screen of ML648B.
3. ML648B will now mount 2 drives, one as Tools (as CD-Drive) and second as Removable Disk (Drive) – under My Computer on your Windows Desktop.
4. Right click your mouse and then select the Format option. When the Format Removable Disk window appears select the Start button to start formatting your MP3 player.

Charging my gpx ML638B

It will if it is a mini-USB plug. The mp3 has the mini-USB cord bundled, and can be used with anything with a mini-USB port. My cell has the same port, so I can charge it on the PC like the mp3, and can use the wall socket charger for the phone on the mp3.
