The fact that causing the unit to die isn't all that easy is a testament to the fact that these devices are much better designed than most people would think. Unfortunately, due to the fact that this device is owned by not just you, but somebody else as well, I'm going to have to close this thread for the sake of protecting the site against any kind of legalities that could be involved. Hopefully, you've been enlightened already.
Just buy another laptop, theres no need to kill this one and it also ends the 'single laptop' issue when your travelling.
Wife might not like it but once she sees that you need it for work and this was a better solution then breaking the old one she'll understand. Two is better than one. Isnt that why you have a pc at home? so you each have one??
