Acer Aspire 5742ZG Core i5 560M upgrade issues

Hello everybody I know this may not be the best place to post this, but I didn't find it anywhere else. So my problem is that I have a Acer Aspire 5742ZG and I bought a i5 560m processor for it and well it said that it supports it but when I got it and put it in well all the laptop did is turn on and did nothing else no picture no loading nothing, so far what I have found out is that the bios doesn't support it. I have done a bios upgrade to the lastest and well still nothing, but I have seen on youtube that somebody had this running with i5 520m and well I would like to ask is there some kind of modded bios to get this working?

 

So which BIOS version do you have exactly?

I moved the post to a separate thread.

 

Thank you, well I have v1.30 this is the lastest one I think.

 

It's weird because what should have happened if BIOS wouldn't recognized the CPU is that it would start- display some warning like "microcode unknown, to skip press F1" and start normally.
That's what happened to my 5740G when I upgraded CPU to Core i5 560M without updating the BIOS first. It did start with this "press F1 to skip" message and I actually updated BIOS with new CPU inside.

Also 1.30 is the most recent BIOS and should work fine. Are you sure that the CPU is in working order?

 

Well how I bought it from said yes, but it can be that he just lied. It doesn't look damaged. Is there any other way that I can find out that its working?

 

You don't happen to have a different Arrandale laptop in your household?

 

Well sadly no.

 

The only thing you can easily do is dismantles the notebook again- check if your old CPU works and if it does, check again if the new one does.
Does 5742ZG use Phoenix BIOS?

 

Well yes the old one works thats what I am using it with right now, can I get a link to v1.30 bios I want to reflash it but I cant get it from acers site. I really dont know if its Phoenix BIOS or not but I'll check.

 

There's no point reflashing the BIOS but if you want to- here it is.

 

I checked I dont have Phoenix BIOS bios I have InsydeH2O bios.

 

I think I have found out why its not working well I just cleaned it completly from the termal paste and well now at bright light I just saw that at the smaller chip on one of its corners there is a really really small part missing but its really small, but I think that why its not working.

 

I have Phoenix BIOS- it's possible that these BIOSes would acct in a different manner if presented with a unrecognized CPU.
