Purchase Guide Before purchasing, you need to check the computer model at the bottom of your laptop to see if it is consistent with the title of the link to the purchased product. Avoid losses caused by wrong purchase. If you don't know whether the product you purchased is correct, you can contact our GBOLE customer service. We have someone to contact you and help you purchase the model that matches your machine. Or provide us with the machine model picture and screen picture at the bottom of your original notebook. If you are not sure whether it is the correct item you need, please contact us with specific model and pictures of your original screen. Sincerely?
