If you re-installed the Win 7 OS back to factory specs, the notebook should be as it was when new. Suggest you go to their webpage, and contact them. Sounds like the keyboard has a malfunction. You could try borrowing a USB keyboard, as a test.
I am having a problem with my net book. It's a NEO Basic B3281. My OS is windows 7 starter edition. Whenever I am working with an office program. the menu bar is always activated even if i am not pressing the alt key. causing me a lot of problem when i am typing. and when i am in desktop and when i right click, the context menu will not appear. I have reformatted my net book because i was thinking that it was caused by a virus but it did not solve the problem. how will i solve this problem? is this hardware related?
