My lenovo laptop keeps shutting down for no reason?
It doesn't like log off or anything, just all of a sudden every now and then the screen will just go black and that's that. I turn it back on and it works fine again and everything i'm just wondering what could be causing it?

This is symptomatic of overheating. The absense of air movement from the cooling fan would be an indication of a failure of the fan. This can be checked rather easily on your model. In the Hardware Maintenance Manual, on page 57 , it shows how to access the cooling fan. Here is the manual provided in the link. Also, A diagnistic CD is helpful because it doesn't load the same drivers as the installed O/S does, and if the crash doesn't appear, it's depending on the O/S and not on hardware. If the unit still crashes, it's hardware-related. Good diagnostic CDs can be found to download, perhaps one of the best is Knoppix (www.knoppix.org), which is a Linux based O/S that runs only from the CD - no installation required. A heat issue can appear quickly, even if the fan works OK, if the heatsink isn't tight on the CPU chip for some reason. Try entering BIOS setup and leave the unit there for a few minutes. If the crash happens there, it's hardware- or heat-related. /RID
