  This is often due to dual graphics cards - the problem arises when one
is being used you think (say the intel i915) - the other one is actually
not off unless you work at it.

  The problem I saw solved used vga switcheroo to turn off the second
card - this was a bit manual as i recall (was also HP laptop).

  Symptom was same - very very bad battery life, and enormous temps.

  You can check this using powertop app and see where the battery is going.

  If you are have lenovo, you can solve this by turning second card off
in bios - sadly HP does not seem to offer that option ...
