I have a Le Pan II and it worked great this past semester, until the closing weeks. After charging, I would remove the plug and the tablet would "click" off. I would plug the data cable back in and it would restart, until I removed the plug. I began a "walk around" of removing the cable when the vibrating motor activated during boot-up. That worked until about a month ago. I purchased a new cable but it did not work too much longer. I took the tablet apart and nothing appeared loose. Le Pan's tech support is a joke and does not reply to emails. Does anyone know where I can purchase a new motherboard for my tablet? Thanks from a poor college student.
