batteries for 11c
#1

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????

Page 233 of the manual suggests three steps:

1. 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.
