Mar 27, 2016 2 0 1,520 Hi all ! This is my first time here and below is the story: I have one netbook acer aspire v5-131 and i made a mistake when i replaced the processor because i didn't check properly on internet and also inside on MB what chipset do i have so i ordered one pentium processor 2127U to replace celeron 1007U processor. It was hard to replace because it is BGA1023 and you need an IR station so i was needed to bring it to IT Servce. Now my netbook is running only 30min and after that it shuts down and the problem is caused by NM70 chipset. I was wrong since the beginning because i thought that i have HM70 chipset which supports 2127U pentium. I was 100% sure that i have HM70 chipset because Acer produces also V5-131 with HM70 chipset and 2127U processor which is available only in Poland market. Now i'm sure 100% that i have NM70 inside and i want to replace with HM70 chipset or HM75 or HM76 or HM77 but i'm not sure if my bios 2.21 will support one of this chipsets. If i replace my chipset with HM75 or HM76 or HM77 i could use i3 or i5 or i7 processors with maximum power of 17W but i'm not sure if my BIOS will support these processors and also these chipsets. For a moment i decided to order and install HM70 chipset which i know that is supported by this bios version because Acer already produces V5-131 with 2127U and HM70 chipset. I really don't want to remove 2127U because it is really good for this netbook and actually i like to replace NM70 chipset with HM70 which should cancel the 30 min timer. If you have any ideea that my V5-131 with Insyde bios version 2.21 will gonna support HM75 or HM76 or HM77 and i3 i5 or i7 (17W processors), please inform me and i will change my mind to order maybe one HM77 and one i7 processor and that's it... * Pin configuration is the same for this chipet series NM70, HM70, HM75, HM76, HM77 so regarding hardware no problem. Maybe there is a software problem with my bios version but this is what i want to know from your side. Thank you for your help and i wish you a nice Sunday and a Happy Easter! Solution Regarding Poland you can check in internet that you can find Acer V5-131 with 2127U and HM70 chipset. For example type on google NX.M88EP.004 and you can see that is sold mostly in Polish market. Now I ordered for beginning HM77 chipset to see if will gonna work. I managed to replace the CPU in one IT Service center for 50$ with success. The process is not complicated if you have the proper skills and tools especially IR station, stencil template etc. It is true that you spend some money but I love too see this netbook with one i7-3687U which is my plan for the future... I7-3687U is the best 17W processor supported by HM77. I cannot install higher than 17W because my power supply is not able to maintain the load and also the stabilizers... Sort by date Sort by votes

Oct 15, 2009 6,905 0 36,960 How you even managed to upgrade it, is beyond me. It's BGA, soldered to the motherboard. It's also not not Poland-only, since Intel doesn't make national processors. It was OEM only which means it was packaged in trays and sold in bulk, not in retail boxes. THe BIOS is closely associated with the chipset. I can't even imagine a circumstance where it would be cost-effective to spend money on the work required to re-solder the BIOS ROM and hope it will work with the other circuitry on the motherboard. http://www.cpu-world.com/CPUs/Pentium_Dual-Core/Intel-Pentium%20Mobile%202127U.html Upvote 0 Downvote A

I cannot install higher than 17W because my power supply is not able to maintain the load and also the stabilizers from MB have the same problem or maybe I am wrong. Let's say for beginning I will try to install HM77 and after that I will install i7-3687U... I hope as well there is the microcode in my bios version 2.21 for this processor...
