@ah1234 sounds like the battery contacts may have either been to destroyed by the alkalinity of the old batteires or just not making good contact with the rest of the Leapster. You can clean the contact with some vinegar on a cotton swab (may have to repeat this a couple of times depending on how bad they look). Once properly cleaned check to see if you have better results with new batteries. If not, then you will have to open the leapfrog. Try the instructions [http://www.ebay.com/gds/How-to-Fix-a-Cracked-LeapPad-Screen-/10000000205781030/g.html|from here.] Take plenty of picture while you do so. You need those to reassemble the device and/or make a guide for the rest of us by [https://www.ifixit.com/Guide/new|following these] steps. you can also post those images with your question, by using [guide|21499|this guide] so we can see what you see.
