You should only replace the internal components of a laptop with the same part that came out. Not following this guide will cause undesirable thermal conditions.
Honestly, with the known issues of an XPS 1645, I would say your better off buying something more reliable.
Thank you, Sir,
For the tip. I just fixed the issue with a call to Dell tech who will send me a 130W adapter.
Moving on, at
my processor is on the left.
it shows that my (the) PM55 chipset supports both.
it shows that I can upgrade to the third generation, at least technically.
Is this correct?
Clarksfield, Core i7-720QM, 4 Core, 6 MB L3 cache, rPGA-988A socket, 45Watts TDP, 45nm Process, DMI, PCI-e, 2* DDR3 Busses, (Sep 2009 release date)
Ivy Bridge, Core i73990QM, 4 core, 8MB L3 cache, rPGA-988B socket, 45Watts TDP, 22nm Process,Direct Media/Integrated GPU, (April 2012 release date)
Glad to hear you got a new power supply.
My first two thoughts are:
- 3rd gen i7 cpu has a higher TDP from 45c to 55c
- you would need to check if your board needs a new BIOS to support 3rd gen cpu
I noticed there's a few BIOS downloads, but haven't located any release notes for them.
I don't know enough about Dell products to know if these are a concern, but if it were me I would try to establish the max tdp for the board and find out if it needs a BIOS upgrade for gen 3 cpu.
