My USB pen from Toshiba Wireless Mouse N745 got stuck inside and I can't get it out

what is a PEN?
a Pen light sized battery? "AA or AAA sized?
what is a pen.?
this device is super rear, i looked for manual for you, got zero.
I'd retire, it if you can not open it and replace the old old batteries.

The top should have a button to release the receiver (on the lower half). If pushing this does not release it, you can disassemble the mouse fairly easily (you do not even have to break the warranty seal). Removing the cover to install batteries, you should see two screws. Remove them. on the bottom, underneath the upper-left corner of the "Acer" sticker is the third screw. Once disassembled, if you look at the top, you should see two white "tabs" that when depressed should release the receiver. If this still does not release it, you can then remove the bottom half of the mouse and then lift (since it's inverted now) the tabs. Hope this helps!

I don't know if this is the same as my mouse. However I have a satellite1955-S803 with wireless detachable keyboard and full sized optical wireless mouse. The original owner said it came with the laptop.
First I tried very hard to get the keyboard working. After a frustrating day of calling Toshiba, I noticed the "detachable" latches. I removed the keyboard to find a battery compartment. 4 days go by with me calling Toshiba trying to get a replacement. Finally found a battery at batteries plus that does work. about half the mAhr of the original but hey it works.
Now to the mouse. Replaced the AA's batteries but couldn't tie the mouse to the computer. I run linux so no M$ driver would help. Finally found a PDF of the manual and it says "if the mouse has trouble activating, press the wireless mouse button on the laptop."
That button is on the front left edge of the laptop (where the "Intel inside", "XP loaded", and "nvidia" stickers are located ) just to the left of the front silver "mode" button. Under the mouse press the connect button. (round near the optic laser but un-labled) then press the wireless mouse button on the computer and there you go. It just connects and works.
2 weeks I looked for this and it was just that simple.

if u now on line i can show u [email protected]. ther is a two part of mouse . back side of mouse cover pressing we can open mouse . there is a plastick lock cleap on mouse.(nepal)

weare looking two part on the above of mouse. one side of scrool and other is only cap add printed( as logetecc). we slould press and pull againast scrool side there is amsall plastick lom.

there is a button just behind the scroll wheel, push it and the usb unlock and come out.

There should be an eject button on the lower portion of the mouse. Press that button and the receiver can be removed.

Hope this helps...please share your experience by voting on this solution.

if u look seriously. you can get above side is two part and below side is one part, press above scroll ,'againast side of the cover and pull (there is a plastick lock.)

Try replacing the batteries or if it has rechargeable batteries, try removing and replacing them. Also clean the red lens on the bottom of the mouse with a cotton swab. Good luck!

Plug in the USB. Look under the mouse for the select button to the "on" position. Ensure batteries are good.
