Using Windows 8? Move your mouse to the corner of your Windows. And a bar with 5 icons will appear. Click on the gear icon, settings, power, shut down. Or just Ctrl+Alt+Delete and there will be a shut down button. Or press Alt+F4 at desktop there, choose shut down. If really cannot do anything, press the power button of your laptop for 10 seconds.

I'm a Lenovo Y400 user..its performing well until now...Malaysia set i guess, not US

but windows 8 kinda annoying like fck....windows 7 a hell lot better.

Not sure about the Malaysia set actually. Cause I bought mine in Malaysia and I assume it as Malaysia set, so far no problems

Windows 8 is really annoying for me. But then, I'd start off with some of the advantages of Windows 8, at least for me. It boots up pretty fast, around 10 seconds or less, even without an SSD. Windows 7 starts up takes like 1 minute. Windows 8 is beautiful, the apps in the apps stores are amazing, especially the games and social networking apps. The security is powerful, blocks all incoming files or virus from pendrive or hard disk.

But it's annoying most of the time. Dont have the start button, maybe cause im get used to the start button. When i hover my mouse to the left corner of my desktop and i click it, instead of Start button, we will navigate away to the apps User Interface shortcut in Windows 8. Shutting down is a pain in the arse, either hover the mouse to the right corner and let the user bar appear and click options -> settings -> power -> shut down, or alt-f4. When playing online games, especially HoN or Dota 2, we tend to use lots of the hotkeys, especially "alt". I always mistaken "alt" button with the "Windows 8" logo button..when i click the W8 logo, it will go to the apps shortcut page, and i press again, sometimes it might just go to desktop...wasted few seconds there, when i open back my game, i die already.

Just played Crysis 3 with my Y400. Performance aint that good. But can play the game on Very High settings on 30 - 40fps ish...provided that i put Low for shaders, shadow and water effects
