Re: Laptop Upgrading
Depends somewhat on the brand of laptop. Many model series use interchangeable parts so the manufacturer can offer a range of specs using the same basic chassis.
*IF* you can get the desired parts then some amount of upgrading might be possible. Ebay can be a good source for parts.
My laptop is a Toshiba with this model offered in a range of options & specs:
RAM & HD of course, plus
Processor speeds from 1.6 - 2.0 GHz
Wifi
Bluetooth
Ethernet
XGA, SXGA & UXGA screens
a couple graphics processor options
standard touchpad or the enhanced 'Cpad' (combines an LCD screen with a touchpad to give additional functionality)
DVD, CD-ROM, DVD/CD-RW combo
Any or all of these can be upgraded in this model *IF* you can get the parts.
NB: My wife's laptop is the same as mine so when a few bits started failing or were broken when I trod on mine one dark morning pre-flight (my beautiful 1600x1200 screen! sob..) I bought one for parts off Ebay & repaired both machines. I already had a CD I bought a couple of years ago containing Toshiba's field disassembly & part replacement manuals.
