I repaired the seven broken traces but obtaining the same three beeps error when started. I thinking there is a bad IC because when in the first time I powered blowed a capacitor. I think that I can put in the trash. 🙁

The three red line are good. I removed two resistors and four pin jumpers and I found 7 traces around battery interrupted. In the red circle the traces. Next days I'll try to repair.

I think that the fun is to making the room with computer/parts from I when was young and with the computer/parts that I dreamed. The games list is very very long and I don't know if I will play...it's very long. I think it's more nostalgia...but I'm verry happy when I playing some games with ROLAND- …

I tried with headset and others loudspeakers but the problem is the same (both loudspeakers work in the other computer). I found another SB Live! with 5€...I think is more easy to replace the card with another one. Thanks guys

I replaced the CMOS battery with another one, same model. Now the computer can poweron correctly and I reinstalled the OS, drivers and some games. I don't know the reason about the old CMOS battery because the voltage is always 3.6v. I'll keep going with usage and tests. Thank you

I checked the battery now and it's 3.65v. I verified as is without a connected pin. I remeber that it's connected with correct way (+ and -). I removed the old battery, many months ago, and replaced with this. It's worked. Do you think I need to add a diode? I don't undertand the reason because the …

At the end the main problem was the transistor T3, BU903 which break down the fuse everytime. In the first time anyhow I replaced two gold capacitors from 0.47 microfarad and orange 100 microfarad. When I receied this Olivetti I replaced the CMOS and for many months it's worked I don't know because …
