Hi, I Have Acer D150 netbook, for some odd reason keyboard's letter M, Spacebar, Win Key and Fn keys are not working, all other keys are working fine. I have restored it using Acer recovery program but still no luck. Please help .
Likely just a hardware problem. You can get a new keyboard on ebay or just by googling it. They are pretty easy to install. Sometimes you have to pop off the top cover between the screen and keyboard before you can access the screws holding it down. Here's the keyboard for $13.50: http://stores.channeladvisor.com/laptop-refitters/items/item.aspx?itemid=7339300
