CPU upgrade for Inspiron 17r N7110

You can find a video on youtube on how to get to the processor on the N7110 you have to take everything out of the case right to the back of the case.  I would not do anything until your machine is out of warranty, then you have to be sure the BIOS on the motherboard will support that cpu or all your painstaking work will be wasted.  FYI if your cmos battery dies you have to completely take it all apart as well since it is apparently located in a holder on the bottom of the motherboard.  I would not recommend that a inexperienced person try this procedure, there are dozens of tiny screws and gentle disassembly. Then when you are finally down to the end with the motherboard all out there is a heat pipe that has to be carefully removed before you can finally get to the cpu socket.  So why it doesn't appear impossible to upgrade the cpu, if you aren't good with this sort of thing you could end up destroying your machine and there doesn't look to be an easy way to bench test before you reassemble your laptop.  The only easy upgrades appear to be the hard drive and lan card..if the keyboard dies the replacement procedure for that is pretty simple too.   If the bluetooth card is socketed, the video I found on youtube doesn't show where it is.  

I'm sure some industrious upgrader out there has information on what cpus the various bios will support, you can try to google N7110, cpu to see what you can find.  I want to ugprade mine too at some point, and while it looks daunting I'm not too afraid of the process but I'm not doing it right away either.  If you've never tried to fix things like your psp or other laptops it's probably way too much for you.
