I've worked on laptops from all major manufactures, replacing hard drives, optical drives, RAM upgrades, LCD screens, LCD inverters, touchpads, fixing broken keys, etc. Google is your friend when it comes to needing disassembly guides for some of the more obscure ones and 9 times out of 10 there aren't any screws left over too! ;-)

 I have 4 PCs setup through Verizon DSL and a Netgear switch. My personal PC runs Windows XP x64 edition. Another PC runs XP Home, a laptop which runs XP Pro is also attached. There is also a linux server which hosts my website including: blog and photo gallery, my fileserver and whatever else I feel like experimenting with. All PCs have secure remote access with VNC tunneled through SSH on a not well known port.
