IFINGER batterij Cmos Bios voor HP ProBook 6450b 6455b 6460b 3V Mainboard

I was surprised to find TWO batteries included. One with a 3-wire connector and the other with a 2-wire connector.My HP6460b has a 2-wire connector to the CMOS battery so I tried to fit that, but the plug on this battery is NOT the same as in my laptop. I did manage to fit the new battery by cutting the leads off the tiny plug on the old battery, then cutting leads on new battery and soldering the old plug on the new battery. The battery does work, but unless you have soldering skills you will not be able to use it.It is quite hard to find the CMOS battery in an HP6460b, and the youtube video showing how to is wrong. You have to remove the bottom of the laptop. Remove the bracket holding the twin speakers. Remove the CD drive. THEN you can remove the battery.
