I bought this laptop five years back. I extended it’s ram from two to six gb. Firstly it working very good but slowly after few months, I Faced problem such as, my laptop screen is bleenging when I Start the laptop. I have problem with hang laptop, some times it’s Wi-Fi connection was lost automatically for few minutes. And after few months it’s sound speaker not working properly, it working few two three seconds than stopped.it’s bettery quality is I also dislike.i suggest to improve this kind of problems for good results.
