I decided to start this thread because I bought a Dell Inspiron after my old Thinkpad T420 apparently kicked the bucket. Literally this piece of shit had problems from the get go: shitty Linux support, garbage keyboard and mousepad and worst of all, the bastards at Dell force you to use a first party AC adapter to charge the damned thing. That last part would have been fine if the AC adapter that came with the piece of shit worked. Instead, I have to use a third party AC adapter to run the laptop and I can't even charge it. I'm going to sell it to my dad in the hopes that I can at least get some of the money back from this waste of money and I bought another T420 from ebay for relatively cheap (don't worry, I told him all of the problems with this laptop and he has like 3 other laptops that work fine so he'll be fine). Long story short, never buy a Dell laptop.
