Any sounds? Does the motherboard runs? Do you hear power supply unit working?There may be many reasons:- power supply is dead (if nothing happens after power-on)- battery is dead- chipset is dead- memory is dead- tarnished contacts (power is not supplied to motherboard at all, or not enough power for components)opix.pl

The first thing I would do is install an new 3.6 volt 1/2 aa Lithium PRAM battery. You can get it here: https://www.amazon.com/Brand-LS14250-Lit
