Can't eject battery

The obvious - Use the eject button when the system is powered on.
If that does not work, use a straightened paperclip and manually eject via tiny hole in the front. Works on or off. gl

this is a longshot, try unplugging it, wait about 30 seconds and plug it back in.

negative you will have to remove the radio and reset by unpluging and pluging back the power plug

Some camcorders have a manual eject button that will open the compartment and allow you to remove the film/tape. Since you again declined to specify the model of your camcorder, I can't tell you whether this solution applies to you.
If you need further information, please feel free to reply to this post, but be sure to include the model of your camcorder.

try disconnecting the battery overnight.

Hi Donna,

Please do be frustated.

Your lovely Bose has problem with its mechanism that cause load / unload totally out of order. If you hear some noise while you turn on the bose or when you hit some buttons, it is telling us the motor still work. Now we need to check the broken gears ( or other mechanism linkage).
If you able assemble this Bose, go ahead to find and fix it mehanism ( you may need some parts replacement.

Note : Be carefully with its laser lens while power on ( avoid direct contact to your eyes).

Best luck,

Jay

Power off the notebook, remove power cable and battery. Then try inserting a paper clip into the small hold in the CD drive to force eject the tray. Make sure you have powered off device and removed battery before you attempt.

Try to reformat your micro sd card using your phone, then plug it into your pc to copy files. Don't forget to properly eject your sd card not just unplugging it. If this doesn't work try reformatting it using your pc then properly eject it.
