Miscellaneous laptop discussions forum: Laptop CPU upgrade on a Vaio VGN-N320e

i thought i might extend some knowledge to Sony laptop users regarding this, since i did indeed swap out the CPU in this laptop with a T2450 2.0ghz core duo cpu that has been working fantasticly.

like anyone without much detailed information to go on, i researched the process over several weeks (when i had the time) then scoured eBay for a suitable replacement. i then ripped apart this laptop, the same one i'm using now to provide this update, and was able to upgrade the cpu.

has there been a performance improvement? yes. i can actually state that my handy dev machine is running faster (and much cooler) than ever before. it turns out that depending upon the cpu family you are working with, you can swap out the cpu without having to reflash your bios. be sure to make sure that the specs for the original cpu match the one you are replacing it with. i did not have detailed motherboard info at my disposal, if i had i probably could have installed an even faster chip.

i could also have overclocked the original 1.6ghz dual core, and that may have also provided an adequate solution. at any rate, just adding some information. i can not in any way take any responsiblity for anyone who reads this post and decides to upgrade thier Sony laptop cpu. open heart surgery on ones laptop is not for everyone, but with sufficient research, it's not that complicated.

my list of *wish i could have from Sony* regarding this issue:

1. in the future please sell budget laptops with upgradeability
2. please stop soldering the video cards to the motherboard!
3. having a diehard user base of loyal Sony laptop owners is good
4. providing that user base with options is a grand idea
5. people who use Sony laptops dont want "bloatware"

i should not have had to scour the internet for information. all of this information should have been provided by Sony for technically knowledgeable users.

and best of luck to all of you!

Hi, i am attempting the same thing you just described (a year ago) and was curious why you selected those processors. Or rather why you did not include the T7800 and why you would even consider the t7200?
(when the t7400 is cheaper and faster than t7200)(when t7600 matches more specs with the t5500 also while being faster than 7200).
i suppose im still trying to figure out which specs are hard-points that cannot be compromised and which are pliable to a degree.
thank you for your information and in advance if you update with new specs.

Hi..

I am having the same needs to upgrade my laptop and I need your help...

How did you remove the top of your laptop SONY VGN-N320E to access the Hard Drive? I removed all the screws from the bottom including the three under the battery and the three after taking out the DVD Player. The top is still stuck. I tried to remove the Keyboard and I did not find the way to get it. I found the Hard Drive but I cannot free it because I have no room for the screwdriver.

I will appreciate your help.

Thanks a lot.
