batteries for 11c Message #1 Posted by dennis thompson on 2 Feb 2005, 8:33 a.m. I removed the batteries for 16-18 hours while using old batteries for comparasion while buying new batteries. When I put new batteries in, calculator won't come back on. What to do????

Press the y^x and ON keys simultaneously and release them. 2. Remove and reinsert the batteries. Make sure the batteries are properly positioned. 3. Install new batteries.
