    It's rechargeable battery, ML1220 type I think.
    That's the northbridge (happens to have an integrated GPU but they almost never die).
    The RAM isn't inserted properly.

        I get no picture when I also attach a com port cable to my tv,any ideas people. Should I go change the Nec Tokin chip? I have the replacement chips here now.
        Thanks all

          Been checking for voltages around by the cpu and inbuilt gpu chip. Getting voltage,but chips L516 and L513 are getting hot to touch ?

            Hi all , Now for some reason I have fan spin for a split second and it goes in a loop attempting to power the fan on again,but if I remove the cpu from the socket it spins constantly. Do not seem to have any volts on the 2 grey coils next to CPU now that we're previously getting hot. Under the cpu chip I have 1v on that capacitor.
            Does this nec Tokin chip look ok in the picture? Doesn't look burnt to me!

            Thanks in advance.

              Oh well, I will have to do guess work as I'm now stuck on what's causing the new issue. Going to change the NEC tokin chip as a last resort,but it still not going to get power back on the 2 big coils by the CPU.

                From the beginning if you just replaced the nec tokin every thing will be fine and the picture will come instantly !!
