CMOS battery is a small battery on the motherboard used to keep settings when the system is unplugged or has not other power. In some laptops it is actually not removable but there may be a jumper or some switch to reset the BIOS and clear all power. Just removing the battery will not do the same thing as also removing the CMOS battery.

Did you check with an external monitor? If you turn it on nothing happens at all, what lights come on when you turn it on? Maybe a bad motherboard. Take it apart, see if there is a CMOS battery in it you can remove, take it out, with no power connected hold in the power button for 30 seconds. Plug in wall power only, see if it turns on. If it does, plug in CMOS and main battery and see if it turns on.
