You can't remove cmos battery to solve the problem. The password is stored in a separate chip on the motherboard and only an expert can know how to reprogramme or to remove the password

If you remove the Bios battery for 10 sec it will restor Bios to original, with no password activate. But it request that you open the laptop in question. But it work on every PC, unplug the battery, a round flat metall plate, let it rest for around 10 sec before you plug in in.

Make sure you have removd laptop battery before you open the laptop, and use the right tools for the operation.

I hope it help! Good luck!
