[primoz1]

I think the 7520 as a 17" Lcd and keyboard with separated numeric keyboard and 5520 as a 15.4" Lcd and a normal size keyboard without separated numeric keyboard, so the problem is on the bios. possible it must be internal configured with acer tools, to accept the keyboard with separated numeric from the 7520.

Yes the problem is, on separated numeric part, no work any key, but all other work OK. What acer tool you got in mind ? Link maybe ?

Thankyou.

Update. Now I buy "working" motherboard ICW50 L07 and keyboard work OK. But sound work only after laptop be on power cca 1 hour and become hot, then audio work with no problem.

So I think, when is laptop hot the pad's under MCP67MV-A2 get connection and sound work, but on start when is board an chip not so hot, not have connection on all pad's under chip, I think it will help to make reball a MCP67MV-A2 chip.

Is any sugestion how to fix this on difirent way ?

Thankyou.
