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)

In addition, the computer worked the last time I used it 15 years ago, that's why I thought replacing dead lithium ion batter would revive it, but no, just the I'm not working tune plays. In additon, I can hear the hard drive, and fans working.

it is more possible that the video wire may be broken, or the VGA adapter is corrupted (try by AV cables if you connected it earlier via adapter). If not I would open the chassis and look for solder cracks. Ah sorry I didn't noticed you mentioned not working tune - focus on the hardware, skip video wires, I was wrong.
