Chosen Solution
Which other models of Toshiba laptops would allow me to use my existing Hard Drive without reloading software? Ideally, I would install my existing drive into another laptop, turn it on and business as usual, (IE. be able to use it without too much configuring and no re-installation of operating system and other software). My Toshiba A75-S231 is, (and always has been), an over-heating nightmare. Due to the design of the cooling system, (fans, air ducting and processor location), keeping it from clogging up with dust and over-heating is impossible. When that happens, I have to expose those components to clean them. Over-heating stops until enough dust collects again. Sounds simple right? Not even remotely easy.
The Satellite A75-S229 looks pretty close. You might be able to upgrade the processor using yours. I would highly recommend Sysprep if you’re doing this with a Windows machine. Sysprep is a good friend. Unfortunately, Toshibas have a tendency to run hot. That is a pretty common complaint across the board with their laptops. Older enterprise grade Dell and HP laptops will usually cost comparatively and run cooler. For those you would be looking for a Latitude or EliteBook. Both of which have excellent documentation!
