For quite some time, I've got issue with notebook, which without the reason turns off immediately. It's not caused by overheating and all the drivers are up to date. Because of this, I needed to repair the motherboard - power management chip has been replaced, however it didn't fixed the cause.
It happens only when ac adapter is connected, however I come to realize, that it may be cause by current fluctuations in the network. I've bought UPS, but it is line-interactive and from what I've heard, it won't help when fluctuations are high or for longer period of time.
I will try to update the BIOS, but I already did that few months ago and it did not fix the problem.
