I bought my lap-top during this winter holiday, it is a X61 from lenovo.However, as long as I brought it to Singapore,strange things began to happen.Firstly, I noticed that after calling the lap-top sleep, it oftern woke up in several minites without I touching anything.Later on,the welcome screen disappeared.My friend suggested I check the virus, but I could not find any.Then I made up my mind to reinstall my operation system.Everything seemed all right after the new system is set up.Nevertheless, I found one of my folder had been cleared up on day.And same thing happened the next day.......
