ZS600 doesn't boot. Only 4 beeps

flyingdutch

When I switch on my ACER ZS600, the fan starts running, I hear 4 short beeps, and that's it. Nothing on the screen.

I opened the back and this is what I tried already.

 

-take out and replace the memory

-replace the batterie

-reseat the VGA card

-deconnect, clean and reconnect all connectors

 

But so far, still the same problem. Anyone has a suggestion what to do next?

 

Thanks

Hello,

 

Your AIO has AMI bios.

OK. Thx. That learns me that 4 beeps means 

 

"The system clock/timer IC has failed or there is a memory error in the first bank of memory". Given that I've already tried switching the memory module, that leaves us with system clock timer IC. And comes the obvious question: Where is that one located and can one change it??

 

Thanks

Hello,

 

Given that I've already tried switching the memory module...

Have you tried with only one memory module? and the other one?

May be I misunderstood your messages.

It only has 1 memory module. (4Gb). Which I cleaned, moved it from the upper to the lower slot. And I had another memory module laying around. Plugged that one in, both slots. Tried them together. But whatever the memory configuration, I keep getting the 4 beeps. That's why I think I can exclude that possibility
