I had a look at replacing the CPU but it seems to be soldered onto the motherboard. I emailed Toshiba about different motherboards which may fit in my case as they used the same case for several years but they never replied to me Even with Peppermint on it's still a bit laggy and slow.
The only physical components that I've replaced on my Toshiba (Satelitte A665-S0686) was the HDD to a SSD & RAM from 4GB PC3-8500 to 8GB PC3-10700 as performance was bad & RAM was crashing with 3-4 apps open..RAM replacement/upgrade stopped the crashes, but the Crucial M4 SSD that was recycled from another unit is what got the lead out. I do know that the CMOS battery is soldered on, so it's no surprise that other components are also.
2GB RAM should be fine for Peppermint, I'm running a full install of LInux Mint 13 on 2GB of plain old DDR 2700 RAM & 7200rpm IDE HDD, Thinkpad T42 built in 2004. It does have a new HDD installed, one that I bought for another years back & recently found in the parts basket. Had forgotten it was there for 5-6 years.
My initial thinking is telling me that the HDD may going south, based upon my experience & many other forum threads having to do with 3 to 5 year old Toshibas. There is a tool to check it with, however it only works with Windows, HD Tune, there's a Pro & Free version. A benchmark will expose this.
When booting & running from the Live CD of Peppermint, trying before install, does the LIve Mode run faster than the installed one? Normally it's slower from LIve CD, but is faster from a Flash drive. However if the HDD is getting weak, it's possible that the LIve CD session will be faster, Running from a Flash drive, it should be slightly faster than your HDD & that's an option for you. Just wondering, is this your computer?
It would be great to have the specs of it to assist in determining what's making it slow. 5400rpm HDD's are dirt slow these days, especially if it has a few years of wear on it. I'm more used to helping solve hardware issues with Windows installs, because of the available tools (or what I'm used to working with). However, Peppermint may have some benchmarking tools of it's own. I just don't know how these tools interpets the SMART data. Oh & to do a RAM test, there's an option for that on the Peppermint pre-boot screen, just drop down to Memory Test & run the default one. This will eliminate that component, though if the RAM is bad, there's normally crashing. Note that DDR2 RAM is much more costly than DDR3 of the same amount. Hard drives are low cost for notebooks, 500GB ones as low as $45-50 on promo. I have seen 60GB SSD's for $50 on promo at Newegg.
Buy a new Laptop it will be cheaper.
That could be very well true, especially if multiple components needs replacement. Look at it like this. How much do you value that computer to be? Or alternatively, what would you take for it? If it costs more to fix it than it's worth, then Nick's quote applies. If a lite OS such as Peppermint is running slow, tell us, how was Windows running on it?
Being that this is a 2008 model notebook, I'm very reluctant, w/out personally inspecting it, to advise wildly spending hard to come by cash on what, without at least a HDD (preferably SSD upgrade at today's prices) & RAM upgrade, you're not going to get a major performance boost from. If you have a spare HDD around that you can swap out, that would be great to try. Notebooks also, especially if obtained second hand, are likely to have a lot of wear & tear, compared to a tower PC. Dust gets packed in them very easily, in the right conditions, after just a year or two. This is noticable by the fan getting louder. There's vent slots & a heatsink with fins behind it. Those fins gets clogged, it runs hot & any legit tech on this forum or elsewhere will tell you, heat is the worst enemy of electronics. Especially notebooks, so little room to breathe.
9 out of 10 times, every time I hear a loud notebook fan, if I blow short bursts of canned air into the vent slots, it gets much quieter right then & run cooler. However, that's a temporary fix only. The notebook needs to be opened for proper cleaning (blowing it out really well) & the heatsink cleaned well, as well as the CPU surface, with at a minimum, 80% rubbing alcohol, All of the old paste must be removed. Then re-apply just a drop or two (about the size of a rolled oat (as in oatmeal) on the CPU & optionally GPU, then reassemble.
My point being, considering the age of the notebook, if these things haven't been done, they need to be. And if you don't know how, not want to yourself, it's going to cost.
There are plenty of notebooks more powerful than what you have with a warranty for $300-400.
And if you have a Flash drive, you can remove the HDD & install Peppermint straight to it, Not a permanent solution, but will buy you some time.
Keep us informed & Good Luck.
