    I done all that ..and plus I took the motherboard battery out as well and still nothing moves inside .. but .. I saw if I let the AC connected it gets hot..its something INTEL AF82801 IBM L932H187 SLB8Q and this gets very hot if I let the AC plugged in :confused:

    Is your battery flat ? maybe your charger is at fault.

    82801 seems like bridge, if it gets hot it can be short circuit somewhere or in chip itself... I think heatgun won't help.. chip swapping(not sure if it'll work + expensive)/motherboard replace seems like better option. but if you have heat gun you can try.. just don't let the temp to go above 360C and be cautious.. you can overheat pcb.
