Last week the battery in my SP3 failed. 7whr indicated capacity left. Lasts for about 20 minutes on battery. I called the Microsoft Business support numbers at Global Customer Service phone numbers which resulted in a string of promises about phone calls back from technical engineers that I never received or promises of emails with instructions I'd need to follow for replacement which never came. At this point the best I can tell is that they seem to want me to send the device in to their service center and that once it's received I should receive a replacement device in 5-10 business days. (although they can't tell me where to send it or for sure how long it will take or how much if anything it will cost) This is completely unacceptable. First, this is my business computer. I am not going to go a couple of weeks without it. Second, at this point they can't even return a call or send a promised email to me. There is NO WAY I am going to send my device to a company that treats me like this. Anyone here have any alternative solutions for me? The closest store is 70-some miles away and will require me to spend an entire day to get there. Not really an option for a business user. This is my second Surface, quickly becoming my last.
