Hi I am new to this forum and ask others if they have had the same problems as me with this laptop. I bought 2 of these at Xmas and they haven't worked properly since. Both of them just totally power off, I've had them back to PC World 3 times and each time they state that they are not shutting down with them, they advised me to buy a laptop cooler which I did and they are still shutting down. I have taken them back to factory settings and have anti virus software installed, they are both still under guarantee but feel I am getting nowhere, PC world state they have had no problems with this system and wonder if anyone else is getting the same problem.
