How do you know this? Are you referring to my BIOS. If you had the Pentium M like he originally thought, then he would've been correct. However, since you have a Pentium 4-M then you should have some upgrade options available. Again, we're not giving you any guarantees. To be completely honest, if you can even find a P4-M you'll probably spend more on the CPU than the laptop is worth. I'll look into prices on eBay, that's if I can find one that's compatible. Now I have a CPU to sell... ------- EDIT------- Found some CPUs from this list on eBay. Here's the prices incl. postage: 2.6 Ghz $AU157.86 2.4 Ghz $AU129.44 2.2 Ghz $AU86.50 2.0 Ghz $AU46.00 or possibly cheaper. I'm leaning towards the 2.0Ghz just because I'm poor. I'm I really going to get much more performance out of the 2.2Ghz? Also the 2.0Ghz is from Australia so I feel more confident it won't get lost in the post and I don't have to use Paypal. -------------------- Yeah I'm gonna buy another stick of 512MB soDIMM DDR1 226 RAM for the spare slot. I don't think I can get access to the other one, can I? I'm also getting a bigger and faster HDD from 20GB to 160GB and 4200rpm to 5400rpm.
