Laptop fan doesn't run after initial BIOS power-on self test.

What I have tried:
- Checked bios for fan settings (none there)
- Changed windows power options from passive to active with/without charger (no effect)
- Ran speedfan (doesn't detect a fan)

Fujitsu Siemens Amilo Li 2727

After I turn it on the fan spins for a few seconds and stops. Windows 7 boots fine but you can feel the processor getting pretty damn hot.
I did clean the fan recently, so that could be a possible reason why. However it does work for a few seconds when the laptop is powered on.
I'm sure this is not normal as usually the fan runs continuously as the laptop boots.

Any help would be appreciated, Thanks.

Well you may check temperatures. If CPU reaches 60 degrees you'll feel hot air on exaust but if you are feeling it this means that fan spins, only slow. Same thing happened to me recently when I cleaned old LG laptop with P4 in it. Fan did not even started until 60 and was reaching max at 75. Summary= clean fan - more effective - slower spinning.

But before it would run constantly from boot, even when it was brand new. I can tell if the fan is spinning because I haven't put the screws in and tested it and can clearly see it not moving.
