There's no way an i7-3630QM (45W power draw) is going to work in your system that's designed for a 35W i5 CPU.

i understand...

but i saw at microsoft web site, my chipset (HM77) was compatible with the processor.

is there anything i can do solve this?

if not, how can i know which processor to buy ?

Hi jhon tiro,

I was able to upgrade mine from i5-3210M to i7-3920XM
Yes you're right that the HM77 is compatible, as its max output is 55W.

You must know, that when you upgrade to i7, there will be BSODs ocassionally due to insufficient power as I have now. Also, your laptop will heat up very quickly when running processor intensive software.

Cheers.

Bigger issue here.

Got the 17W i5-3427U.

Any infos about upgrading to i7-3687U (17W)?

Any suggests? Bios mods?

All of the "U" processors are FCBGA -- they're not socketed, but rather soldered to the mainboard.  The only way to upgrade is to replace both the CPU AND the mainboard, assuming a mainboard is available that will fit the system you have.

Please tell you are just kidding! :emotion-8: 

Just found a i7 3rd gen 17W on ebay. :emotion-7:

Nooooo! :emotion-39:

I'll open to make sure. Before announce it cheap. :/

Cpu-z says it's a Socket 988B rPGA.

Yeah. Found one on ebay.

Dammit! This NB is giving a lot of headache. 

Edit:

Thought in this one:

And they says it isn't embedded. :emotion-12:

Edit:

I think mine is this one 

http://ark.intel.com/products/65707/Intel-Core-i5-3317U-Processor-3M-Cache-up-to-2_60-GHz

It only reaches 2.6GHz on turbo.

Scroll down to the "package specifications" part -- you'll see FC-BGA 1023.  That's a ball-grid CPU -- these are not socketed.  They're hard soldered to the mainboard.

I wouldn't count on CPU-z to correctly identify the package type.

As for your i5-3317U, it's only going to reach 2.6 GHz on turbo boost - that's its maximum speed:

I don't know of any system manufacturer that promises upgradeable notebook CPUs - none of the mainstream brands do.

And Intel has basically discontinued just about all PGA CPUs for notebooks as of the advent of the Haswell line -- and appears poised to do the same for desktop CPUs with the forthcoming Broadwell line, so you won't have any purchase options with any other vendor.

The age of replaceable CPUs in notebooks is just about over - the door is about to close completely.

What a trick into the buyer, huh? They should advise about not been upgradable.

I've decided not buy Dell again. Won this NB. Now i'm absolutely sure about it.

Thank you for the info Mate.

Perhaps briefly for those systems with socketed CPUs - it  may do just the opposite for systems that have the newer CPU type, since just about any internal failure requiring a replacement mainboard will be costly enough that the system will be scrapped rather than repaired.

Well, this may boost used NB market.
