Worst piece of technology ever. E and L do not work. I have: Uninstalled the keyboard Turned the keyboard around Held the power for thirty seconds followed by the power + volume up for 15 Checked for new drivers checked that all SP and updates are current cleaned contacts Months of this crap. My other favorite is trying to select suggested words while using FB in three different browsers. Words duplicate themselves and parts of posts repeat themselves. Any advice on making the over priced worthless garbage work as minimally intended? Civilizations have been able to produce typing machines for years. Surely, someone at Microsoft has the skill to enable the E and L key to work. This is a known problem. MS should be ashamed to sell this.
