I bought this laptop last year. Now, it is facing an issue. For a last few days, when I shut down my laptop, it automatically restarts. I thought, it is affect by virus. So I did a full scan. A tracking cookie appears. I deleted it. Then I shut down my laptop. The only thing I use to can shut down my laptop is by pressing the main power button.
i had same problem.I had tried all methods said in the tech forums.nothing worked. even computer service personnel could not solve it. With no hope I reinstalled my anti virus and did a complete computer scan..guess what..it found a trojan virus..after deletion the error rectified :)..virus corrupts many programs including antivirus..u have to reinstall..
