Schneider EuroPC PSU??

3 beeps on schneider means settings incorrect... the system boots fine! I find mine thrown away and i couldn't resist taking it! I use it with schneider's CM14 colour monitor! Pretty nice System i must say!

I'll derail this thread.

I got a EuroPC, and its battery has leaked of course. It does power on, the speaker lets out a "tick" or "knock", Num and Caps lock leds blink once, then nothing. The CPU runs warm.

I've tried with another known-good Siemens 8088 (no change), checked if the EPROMs are working (yes - also dumped them).

When powering up with an ISA diag card, the RESET line goes down as expected, and the IRDY led lights up (does not do this without a CPU). The FRAME led doesn't budge, so unfortunately there's no activity on the bus. The attached CGA monitor gets no signal at all (all white screen), neither does a VGA monitor with an ISA VGA card.

I'm looking for anyone who has done such repairs on the EuroPC.

Here's an image of the affected part of the board after a bit of cleaning: http://gabucino.hu/tmp/euroacid.jpg

Did you check the traces that show damage for continuity?

You realize that if there's damage to areas on the inner layers there's nothing that can be done.

Yes, the seemingly damaged traces are intact.
