ASUS K52JR, i7-748QM. Battery keeps power for about 1.5 hours so I assume it's not dead. Charger charges.

1 Occurrence: Watched season on VLC player, charger on. Suddenly laptop shuts off, power led stays. Shut it off (properly) by keeping button then luckily turned on again.

2 Occurrence: Several days later watched on VLC again when it shut off. Power led stays, but now can't do anything to turn it on. Pulled out battery, done that 45 seconds thing, put back again. Can't turn on it just that power led lights up. Just kept it that way for hours, laptop was warm...and then all of a sudden it turned on.

3 Occurrence: Turned off doing daily things, doesn't turn on no matter how long I wait. Damn it.

Fan not working, cpu heats up a bit like it pretends to be working, dust cleaned inside. Always just that power led works when button pushed with battery or just charger in.

UPDATE!

Since I reassembled laptop, left only motherboard, this happened - I put in charger so led light up. Then I put in hdd - its indicator starts flashing, also wireless indicator lights up. Later I connect wifi adapters connectors - fan starts! Then I keep power button, it looks like fan turns off but caps, num locks, hdd, wifi indicators an led keeps light up. Did it ran out of its mind?

Whats happening?

I can't seem to find much in terms of support from Asus's page. Can you please state what your OS is as well as it's SKU/full system's specs? Have you made sure your BIOS is up to date? If the laptop seems to shut itself off then it's probable that the age of your unit and the continuous running of the unit has led to a build up of dirt in the cooling fan. Have you given it a proper look through to see if the fan isn't able to cool your heatware?

* FYI, you should reassemble the entire laptop with its components before plugging it to the adapter/wall charger to prevent accidental damage.
