Toshiba P300-156, screen suddenly stops

[kenny11]

I just bought the laptop Toshiba P300-156, two weeks ago.

Many times, I met the following problem:
-- The screen suddenly goes off at work, the buttons lock and I quickly throw my hands to "the power button" to restart with recovery.

Is there someone had the same concerns?
Thank you for your answers and your

you draw any power and battery and then pushes power button for 1 to 2 minutes to turn it on then give your battery and alliteration a try and it will operate normally

I have yet encountered another problem, I can not completely extinguish the PC, it will restart only after stopping

Could be a virus ? try to scan it with anti virus

Yesterday evening I had a break this morning I tried again to restart at the opening I found exactly the same windows that I had yesterday when the judgment. it seems strange it all, it means he was not completely cut off then?

In the leaflet, I found the part that concerns me a little problem:

If the internal temperature of ordinates exceeds a certain threshold, the computer automatically activate the standby mode or hibernation and starts off. If the computer is returned to room temperature and refuses to start or if it starts then stops immediately, contact your dealer.
