I purchased a Lenovo Chromebook about 4 months ago so it is still under warranty. The unit will not start and it will not charge. I filled out the proper request for service form but have been given no direction as to how to get it fixed. I tried on line chat three times. Every time I was put in a queue and when it got to my turn I got a “no one is available, please try later”. I have e-mailed several times and gotten no response. The customer service phone is actually lined to sales and not service.
