Hlo guys. I bought this device as kept in mind that hp is a great brand but my expectation was break after using this worst device. When I buyed this device it works fine but after one month it starts lagging and taking lot of time to respond. I think that it’s a result of malware and viruses. I installed an antivirus with licence but it can’t help me. It might be seen that there is hardware problem of device and it is defective. I tried more times but no any way see to slove my problem. I thinks that lenovo is the best option which not only complete but also beat easily to other competitors.
