After recieving a free m700, I had a friend instal all my necessary software. Had zero problems for 15 months, then the battery started dying after minutes of use. I replaced the battery with a new batt. purchased from computer geeks, and it worked great for about the first month. Now it freezes 20-30 sec. after unplugging the ac adapter. It shows it is charging, and will not shutdown when unplugged, just stops any action and sounds like its processing. No diserable movement of the pointer or anything. Plugging it back in will not bring it back either. Have to shut down and restart with it plugged back in. Any ideas, I’m not very compuer literate, but have friends and family that will help if anyone has an idea, they suggested check a forum!
