I bought a acer chroombook C720, it was working fine and charging fine for about a month or two, but one day i left it charging and when i got home i tried to turn on, but it wouldnt and when I looked if it was charging the charging led wasnt on. i left it alone for a month and try to plug it in and charge it but it wasnt workin so I call acer customer servise but they say the didnt know what it was so they send a new charge to see if that was the proble but it wasnt. I call acer again they told me that i could send the chromebook back but it could be a possibility that i could pay for anything they fix which i think is not fair cause i have a year guarranty, and it was about three months that i have bought it. so before sending the chromebook i tried to plug it in to see if it would work and to my surprised the charging led turn on and minutes later the chromebook turn on and it was charging fine. my happiness didnt last long cause three days later it did the same thing it wont turn on or charge again. I dont know what could it be I need help but I dont want to call acer again. if some one can help me please. my guarranty is about to expire in may i dont know what to do!
