Q: Hai, My ipod shuffle when it is connected with computer it blinks organge light.  If i remove no light

If the shuffle still appears in iTunes when you connect it, you can try doing a Restore on it using iTunes, in case the cause is a software problem.

Use iTunes on your Mac or PC to restore your iPhone, iPad, or iPod to factory settings - Apple Support

If the problem recurs after the Restore, it is probably a worn out battery.  It requires soldering skills to replace it yourself, and iPod shuffles (except for 1st gen) are very small.  Not easy to work on.  This web site has repair guides

and parts are available from sources like eBay.

Apple will "service" the shuffle, if it's 4th gen (current type).  Rather than change the battery in your unit, you get a replacement unit.  According to this document, the out-of-warranty fee is $39

NOTE:  If your shuffle is less than one year from purchase date, it is under warranty.

The retail price of a brand new 4th gen iPod shuffle, with new headphones, docking cable, and one-year warranty is $49.

If you leave a lithium battery in a completely discharged state for an extended period (like six months), it can become unable to hold a charge.  It's best to "exercise" the battery by regularly charging and discharging it.

There is something you can try (before taking it apart)...  If you have a USB power adapter (like the type that comes with iPhone or other device), connect the shuffle's USB docking cable to it and connect the shuffle.  Since this is a power-only connection, the shuffle's light should not blink orange.  Does it show a color?  What color is it?

If it's red, you can try repeatedly connecting and disconnecting the shuffle from power.  To avoid wearing out the shuffle's headphones jack, connect and disconnect between the USB power adapter and docking cable.  There are reports that this may "jump start" the battery so it can hold a charge again, for example

my ipod shuffle 4th gen has a solid red light for 5seconds then stops but hasnt been able to charge or pull up on itunes…

NOTE:  If the shuffle's light is solid (not blinking) orange when connected to the USB power adapter, leave it connected for a while.  Solid orange means the battery is charging.  See if it turns solid green, then disconnect from power.  It's possible the USB port on the computer is not supplying enough power to charge the shuffle's battery, for some reason.

After a few hours, the battery should be as fully charged as it can be, even if the shuffle's light does not turn solid green.  What happens when you disconnect the shuffle now?  Does the battery hold the charge, or does it immediately turn OFF?  If the shuffle turns OFF immediately (or quickly) when disconnected, the most likely cause is a battery not being able to hold a charge.  You won't be able to revive it.
