Speaking of laptop I put 400 plus 40 recently into my laptop to fix it. Realized I should have just bought a new laptop and I am very "special" because said laptop is still not working. Now it's having a hardware error. It's been over a year of back and forth with the repair guy, and he and his buddies are so sick of working on it that they find excuses not to come by and get it. If you have a laptop don't think about fixing it; get a new one.
My ACER which has been falling apart since a few months after I got it has been working better then the HP which was double it's price new. My ACER currently has been running on 1 out of 2 hinges for over 3 years now. The roadkill mouse has shorted out. The C and D drive since the beginning behave like a bitterly divoriced couple. It no longer has the origional cord that went up in sparks and smoke, and there is STILL hot chocolate on it where I spilt fresh hot coco on it two years ago. I swear people if you spill hot coco on your computer if it don't kill it you will be scraping it off for years to come no matter how good you clean it.
YET through it all the ACER works better then the HP. I cannot win.
@SparrowHawk want to do some good cardio that works out yoru behind. Get a office chair that rolls well. Sit up straight and wiggle your butt and hips to cross the room. Feet off the floor and off anything. Only swinging your arms like your boxing to help you. Don't think it's a work out try two times across the kitchen floor then wait for it.
