I very strongly suggest that before calling your laptop dead you listen to existing advice, and either change the BIOS battery yourself or have someone who knows how to do it. Since the BIOS handles all basic functions of a computer - and I mean VERY basic - before Windows even boots or the computer even powers up its components - BIOS battery death will result in corruption and loss of BIOS settings, which CAN VERY OFTEN CAN TAKE A VERY "SERIOUS" APPEARANCE, BUT ARE NOT. Your computer's most basic settings are permanently safeguarded by that small coin battery, ALL computers are, regardless of being desktops or laptops. Normally such a battery takes over a decade before it can die and most people just buy a new computer or motherboard by then, but your battery seems to have died very recently.
Do NOT call your computer fried just for that.
IMPORTANT!!
I just read another thread of yours regarding hardware errors on the graphics card. I find it VERY UNLIKELY that your CMOS errors have anything to do with it, but in case your graphics card has fried the computer may indeed not boot. At this point you are faced with two hardware problems and I don't think anyone can tell which one of them is causing your computer to not boot or charge, although let me tell you that if it was indeed your CMOS battery, you would STILL power up and have some text displayed on screen. Take your laptop to a service and have both problems mentioned to the people there.
