I got a new keyboard in my office. One hour ago i have been restarted my pc 3 times, because power button is in delete position. One more hour ago, i have returned my old keyboard.

Welcome to devRant! I know what you went through. Tough to adjust at first.

My laptop keyboard puts the 'mouse pad on/off' toggle next to the 'close window' button. Bye chrome and all my tabs.

Additionally, is use F2 and F5 frequently, but for some stupid reason lenovo thinks the F keys should require a modifier key to use...

@MadHatrix I know.. My Lenovo does this as well, I think my most frequently used button might be the fn-key
