Sansa clip pc charging problem

I dont know about the playlist. But if the Sansa LION battery goes too low it shuts down. When you plug it into your computer to charge the player, It usually powers up so the computer can detect the hardware being plugged into the USB port and provide power for charge.
You need to plug in the USB cable from the player to the PC and perform a system reset - Press and hold for 20 seconds the power on button and the play button (>||). this should work you may try it on your wifes player?

Check you wire or USB of your computer.

Sounds like the internal battery needs to be replaced.

Hope this helps. Good Luck!

Here's the thing, technically it doesn't need to be turned on because it's supposed to turn on by itself.

I've had a problem sort of like that. It might be the plug, but it also might be the computer. I'd either suggest try plugging it into another computer or getting a new plug.

Make sure the hold/lock is not engaged first.

These are the most common methods for recovering Sandisk's Sansa Mp3 Players. I have been almost universally successful in recovering Sansa players using one or a combination of these methods. These methods do not work if you are having synchronization or music format issues - they are for recovering a player that will not power up, freezes, flashes, is not recognized by the computer, and a host of other issues.

Reset the Sansa Player first. On most models, restart is done by holding the power button in for 15 seconds or longer. Check your specific manual to be sure. The manuals are available from the Sansa website if they have been misplaced.
Download the Sansa Recovery Tool from the Sansa website.
Format - Erases Everything: Connect your Sansa player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "Sansa 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
Firmware Upgrade- Erases Everything: Get the latest firmware upgrade from Sansa - it updates the firmware and erases every song in the player all at once. Note: this method doesn't work if already have the latest firmware. Go to this website and click "Firmware Updater" to find out: http://www.sandisk.com/DriverDownload/driverList.asp
If these fail, then:
Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.
If you get the problem where MTP Device keeps popping up continuously, uninstall the “MTP Device” by going to Start à Control Panel àSystem à Hardware à Device Manager (you computer may vary slightly, depending on Windows Version).
You may have to restart your computer after each of these methods to get them to work properly. Disconnect your Sansa player BEFORE shutting down your computer.

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).

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.

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