Computer worked fine, then after 90 days, power module is not making connection and not charging. I have to move this around and sometimes it charges. Emailed vendor and sent me to Acer customer service, since it was refurbished,  I was sent to third party vendor, only option is to send it in, upfront cost of $300, 20 plus days for repair, if the motherboard needs replacement then it becomes more expensive. 90 day warranty becomes expensive at the end, best to buy new with 1 year warranty.
