So my processor is a crappy Merom Intel Pentium t2390(dual core 1.86 GHz) and I am thinking of upgrading it. I know it is stupid to upgrade parts on a laptop, but I would like some suggestions. I was looking at upgrading to a Penryn Intel Core 2 duo t9900. Do you think that I would be able to do so? I also have a site below listed for where I found socket information for my motherboard.
Make sure you know how to switch out CPUs on laptops. It's a lot more difficult than in desktops. Can you get to the CPU? Also, if you're trying to upgrade for faster gaming, I think you're out of luck. You can't get the latest IGP because of socket differences... it's like upgrading five years down from an i3- 2100 to an i3-2370. The IGP is the same... the chip is a little faster. At least that's how I think it is... the socket changes with every "tock" (give or take), and every "tock" presents a boost in power ("ticks" are usually not so good).
I've upgraded a Merom to a Penryn. It worked well. I got a killer deal on the C2D and couldn't turn it down. It would be much more cost effective today, however, because the C2D T7200 is ~$40 on eBay.
Now, ~$225 for a T9900? Save a bit more money and get a new laptop. Not cost-effective.
Unfortunately I just did this and the chip I used seems to be incompatible Mine was a bit higher end model then what the poster has, a S5927 with a 2.16GHz Pentium Dual-Core Merom. Though I'll admit, I went with one from a MacBook Pro (E8335 or something, ~2.93GHz), but I kinda hope that is why since I'd really LIKE to use a Penryn :\
