Welcome to Lenovo Community Forums!
I’m sorry to inform that your G500 laptop will not support the CPU upgrade as per the technical specifications it is designed.
Do post us back for further queries.

I just did the same thing, i threw an i7 in there and i get "Unsupprted CPU for PCH" .. There is a way around this
i am sure. It just happened to me 1 minute ago and this was the first place i looked for an answer. My first thought was that i use ES processors about half the time- this one happens to be unlocked. It runs like a champ in G500s Touch just not this G500. My first stop is a bios flash-reset. I will post the results when i have found a susessfull solution. Keep in mind- my soulution's usually violate any warranty you have so DON"T do as i do. I do have an OEM cpu i will try first before exploiting the bios. Also a SSD drive is better upgrade for most people as it is more flexible, if your after better video you should have bought a better computer- this G500 is just a testing toy for me, i use a Y580 with twin SSD drives.
G580 is 593730**-- 15- or 13 i think i cant see it.
EDIT: Ok so the OEM 3612QM (FRU: 102500290) wont work as well. It is on the HMM and there are G500 all over the internet with them for sale with 3612QM in them. That leads me to believe the bios is white listed or crippeled or disabeled in a fashion as to force the user to pay lenovo for the upgrade. I checked the chipset- first before google and even the IVY ES i am trying to use should work. Probably whitelist removal next. I'm not sure what is wrong but i dont buy that controller error one bit. more later
EDIT: Ok i got nothing, i am going to repost as my own question. I emailed tech support they sent me here??

What are the power requirements of the cpu being replaced and the one replacing it? My guess would be that there are different mainboards for differing cpu power requirements.

OK, i have come terms with mine. Its going back. It wont run anything else but what it came with. The cpu i am trying to use came out of the same model. Its ON the hardware HMM list. They sell them over at lenovo.. There is something differant about this laptop as compared to my other G500's.. Chipset-MBorad version-F/Ware??? i dont know. It takes 5 screws and 3mins to change the CPU and days to find out why it wont work. I gogeled it others have the same issue with the 500. One(2) last thing i am going to do is call TS and flash a firmware backup from my other 500 to this one..I don't anticpate those options working though.
Steve, if you have the CPU sitting there go for it. I wouldnt buy it. I have in the area of 10ish lenovo sitting here i have spare parts to test with.. Make sure to buy off someone who takes returns -(not me)
Keep us posted Steve, in theroy here is your laptop
EDIT: Ok my issue's solved. Mine is a hardware issue, 2 differant board versions 2 are HM76 CS and the newer one is HM70. So my fault i didnt know these came with HM70 the chipsets. Technically HM70 was not designed for an i7/i5, it shows
Mobile Intel® HM70 Express Chipset
(Intel® BD82HM70 PCH)
Intel® Pentium® Processor 2020M (2M Cache, 2.40 GHz)
Intel® Pentium® Processor 2117U (2M Cache, 1.80 GHz)
Intel® Celeron® Processor 1020M (2M Cache, 2.10 GHz)
Intel® Celeron® Processor 1037U (2M Cache, 1.80 GHz)
Intel® Pentium® Processor 2129Y (2M Cache, 1.10 GHz)
Intel® Pentium® Processor 2030M (2M Cache, 2.50 GHz)
Intel® Celeron® Processor 1000M (2M Cache, 1.80 GHz)
Intel® Celeron® Processor 1007U (2M Cache, 1.50 GHz)
Intel® Pentium® Processor 2127U (2M Cache, 1.90 GHz)
The HM76 will take about anything that fits in the hole. I can live with that, not all computers need to be upgraded or were disigned to be upgraded. I guess this particular 500 is just one of them
