Yep - I had exactly the same thing happen to me. Hot summer's day, arrive at a customer meeting. My previously fully charged Dell laptop has been running since I was on the hot and stuffy underground whilst shoved in to its laptop bag. It's now a nuclear ball of fire, with just 15% battery left and how it didn't suffer a complete meltdown is a strong testament to the quality of the hardware. This happened a bunch of times. Add to this random BSODs, keyboards that would break far too easily, the sheer weight of the thing and more inconveniences I'm surprised I stuck with it for as long as I did. 5 years ago I switched to Apple MacBooks and will never go back.
