If the battery is more than 1 to 3 years old, chances are it needs to be replaced.

Here is a manual, which will give the battery size and number for your model. Tasco Red dot Pro.

Why not just buy a new one from ebay.com?

Since you tried your battery on another pc, then try a different charge power supply on yours. You may have a bad power supply adapter or your battery terminals on your pc may be dirty and need to be cleaned with rubbing alcohol and a cotton swab.

You probably need to install teh video driver again ..This behavior is usually caused by the lack of video driver or a defective video card ..

Simple-- you can also do this during the day on an object at least 100 yards away-- but at night; get the moon centered in the eyepiece and without moving the telescope center the red dot on the moon. This will get you almost aligned-- then put a bright star in the eyepiece and readjust the red dot to center the star.

I have a 1997 Acura 3.5 RL and my remote unlock doors button dont work cause of the battary so I change the battary and it still dont work then I found out that I need a code to reset the remote also when I put the battary in the red light just stay on do anyone know about this

I'm guessing this is a laser printer so start by cleaning the drum. If you can give us more to go on, such as; make and model of printer? Is this only with one document or every document? are the dots in the same place every time? Have you cleaned the print heads/drum? Have you changed your brand of ink/toner? Does your computer give you an error message when you print? The more information you provide the less of a stab in the dark our answer will be.
