We have a PCG-K115Z Vaio. In fact, we've had it for quite a while already. However, we have this problem that very occasionally, the notebook will just freeze completely. The only thing that can be done is keeping the power button pressed down for a couple of seconds to do a hard power-off. There is absolutely no pattern in how/when this happens. The laptop may be working fine for weeks. Also, it may freeze when it was just sitting idle with no CPU or other load whatsoever.
Anyone have any idea what I should look into to get this resolved ? I'm a bit late with trying to resolve this as we've had this machine for a year or so. It never was a big issue since it's my gf's laptop and she didn't use it that much.
Tnx.
