It was a laptop that came with Vista and we tried our best to install 7 but glitches like this keep happening. The maker did not support 7 on that model.
If his came with Windows 7, the maker support will have you unplug all USB things and retest. If it fails they have you reload the OS as they no longer support deep trouble shooting.
Just in case it's malware, look at Grif's advice at 7726-6132_102-5098912.html?tag=posts;msg5099421
Hi, I need help from anyone who would like to help me.the story is bit longer, but ple bear with me and beg u to help me.here is my problem.I have a Lenovo Z460 ideapad, with 4gb ram, 500gb hdd and 380m i3 processor.it's running on windows 7 64bit OS.its working totaly ok when its running.problem occurs when the machine is shutting down.if
the computer is connected to the power and when i click shut down, it
shuts down normaly and nothing abnormal happens, in battery mode also
when i shut it down it shuts down noramaly and nothing odd happens.but
when it's connected to the power and after i click "shut down " button
and when i remove the charger from the port while it is shutting down, i
mean when it shows windows 7 log off screen with the words "windows is
shutting down", it freezes at that moment.blue colour circle keeps on moving and it never shuts down and its not switching off. it is freezed at that moment..it happens only when i remove the charger while it is in the shut down process.it wont happen if i remove the charger before or after shutting down.so
i have to switch it off manually by pressing the power button for
6secs. i know its dumb and the best way is prevent this is to remove it
after or before shutting down.but most of the time i forget that and i keep on removing it while its shutting down.i know switching it off manually is not good for the hdd.so if somebody know, ple help me.thanx in advance..
