I've just broken down a toshiba l40 and am down to the motherboard.
I need to replace the cmos battery. from experience with desktops it looks like a watch battery, but on this motherboard the only thing that looks like the battery is bonded in place. A tiny m&m sized, blue ringed device on the back (viewed from the keyboard side). Is that it, and if so how do you replace it?
you should just be able to push down on it some how to pop it out
