Contrary to popular opinion Thinkpads are not durable as they seem. There are various conditions such as deep coma (when the laptop won't wake from a sleep) or random shutdowns unrelated to heat/any observable cause etc. I thought my thinkpad x201 was like a tank, but then random shutdowns became more frequent. I disassambled the laptop 4-5 times, replaced thermal paste, checked connections, replaced all software (including BIOS), couldn't find a solution. Then I stumbled upon a 45 page thread at the lenovo support forum. Many people were claiming the existence of the exact problem, but the only solution was to "replace the motherboard". At least, apple offers world-wide decent for their products. With used thinkpads, you're basically on your own, no matter how tech-savvy you are. If I were to purchase another laptop for on-the-go usage I will think twice before opting out for a thinkpad for it's durability. Thinkpads are marvelous machines, but in my experience not all that glitters is gold :).
