Never let your wife or kids touch the laptop
Hey I got to use it maybe twice a week and I'm still paying the thing off and what does the missus do
Spills water on it then unbeknown to me tries and turn the thing on
No screen display, $70 later a supposed technician says he can't find where the fault is (he doesn't have the test equipment tell me why he bothered in the first place) but said the memory and HD are Ok
So my technician BIL opened it up and has a look but can't see anything immediate then states he'll confer with the IT people at the Uni he works for.
If it wasn't for the fact I need it for PHD guiding etc and are still paying it off I'd buy a new one as you can pick them up for around $600 these days.
If I do get a new one guess whos not touching it
