Thank you so much! My computer kept turning off after a couple of minutes. I suspected it was a clogged fan (it was). Your video helped me get it apart. Although I inexplicably have 6 screws left over (oops) and I broke one of the plastic connector plugs for my keyboard. I got the pins in place and (for now) the keyboard is working though I use an external one. She's ~12 years old and is desk-bound, so other than moving to clean, no jostling. Again, thanks so much! I'm so sad that Toshiba no longer sells laptops in the US. Been buying them for 20 or so years. Not sure what I'll buy next.
