Sansa clip won't power on. Won't charge either. Though was fully charged immediately prior to problem

Question edited for a lot more clarity.
Question moved from Misc to model category.

Replace the internal Li-Po battery, but try a reset first.

If your Sansa player is freezing, not charging or not turning on, the first thing to try is a reset of the unit. This will normally clear any temporary condition that may cause the player to freeze or not shut off completely, it's a bit like when your PC crashes and you need to re-start it to clear the error.

Perhaps the power source is bad...Try to find a friend who has a similarunit and try there power cord!

Ifthe recharageable battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

Try format, then update to new firmware (save songs or file before do format).

your lithium battery is probably fried.

If you have a phone charger with the same connector, plug in you Clip and leave it overnight. This will fully charge the battery. There is not enough power from the USB port.

This is direct from the sansa FAQs at http://www.sansa.com/support/sansa_clip/faqs 02. Why won’t my Sansa Clip charge when I connect it to my computer? USB Cable
Make sure that the USB cable is properly plugged in and use the original cable.

Computer in Hibernation mode
Make sure that the computer isn’t entering hibernate or sleep mode while the device is connected. The computer must be on in order to charge your player.

USB Port 2.0
Make sure your player is connected USB 2.0 port (1.1 occasionally causes charging problems).

USB Port location
Try plugging in different USB port (i.e. USB port in the back of the computer); sometimes the front USB ports have problem charging up the device.

Battery
Make sure the battery is fully charged. It takes approximately 3 hours to fully charge the battery.

Latest firmware
Make sure to update firmware by downloading and installing the Sansa Firmware Updater.

I hope this helps, and don't forget to rate the answer.

Are you sure the cable you are using provides both data and power to the device? Some cables are data only and will not charge the device despite appearing so.

Has it held a charge before? If this is a new device and has not yet ran down then charged fully again yet, then I would return it.

Locking the player will not allow the player to charge properly, no matter how long you have it plugged in.

If you leave your Sansa plugged into your charging source (wall charger, computer, car etc.), your player might still remain fully charged and just on. If you can, you may want to just leave it plugged into your charging source until you want to use it, so it stays fully charged.When its done, it will say fully charge...it should take a couple hours to charge the device....

Also, does your player have an auto power off or idle sleep setting? You can use this setting to set the amount of time you want your Sansa to automatically turn off after you don't use or listen to music on it.
