Dear Chupa,
I took my laptop to a local repair shop -in my hometown in Spain- to open it up and do all the testings as you suggested. This not seem to solve the problem. My laptop still dead. The repairer suggest to use the aftersale service-warranty of the Seller.
So I am afraid I am gonna have to send it back to Geekbuying headquarters in China for repairing.
Please, I need help in how to address the issue by paypal since it has not expired the protection period (180 days). However, I don´t seem to see any causes to open a dispute: 1) item not received; 2) Received a different from the one shown in the ad; 3) other issues related with the payment.
Any comments, insights and previous experiences with this seller (Geekbuying) are very welcome.
Kind regards.
