EDIT (FINAL REVISION 5/24/2019, AFTER OWNING LAPTOP FOR 2 MONTHS): I thought I was having battery drain issues, but it turned out to be my own mistake! Oops. So after 2 months, the laptop works great still. I have had no issues with Windows 10 (activating it was a breeze) and the computer is performing as expected of a i5-processor with 8 GB RAM. (Fun fact: The laptop I received surprisingly came with a slightly BETTER i5 than listed in the product description!) I upgraded from a much less efficient AMD-A6 processor with only 4 GB RAM, and must say that I LOVE how seamlessly I can run multiple programs/apps at once! I usually have 10+ windows open at a time while streaming in Opera browser, surfing the web in Chrome, editing in large text applications, browsing file explorer, and doing digital art in Paint Sai with my Huion graphic art tablet drivers running. On average, the battery life ranges from approximately 4.5 hours with 50% screen brightness and 2.5-3 hours with 80% screen brightness. To reach a full charge takes roughly 1.5-2 hours. I'm pleased with the efficiency of charger that I received and the machine's overall battery life; it's not the greatest but it is certainly reliable and meets the expectations for a refurbished laptop. I expect it will last for at least a couple more years. Final notes: I gotta say I love this laptop. It just looks and feels so well-made (which makes sense, given it is a premium business-class model laptop), and I love how light and portable it is. The back-lit keyboard and the layout of the mouse/trackpad design are EXCELLENT; I love having two mouses, one at the top of the trackpad and one at the bottom. And the fingerprint scanner is a neat plus too.ORIGINAL REVIEW:I am SO HAPPY with my new refurbished laptop from ITREPLAY. It is PERFECT - everything works smoothly, and it looks brand new. The screen display is as good as expected (full HD) and I love the anti-glare wide-viewing angle. The back-lit keyboard (I can't live without these!) and fingerprint scanner are super nice touches! The battery life is great--WAY better than my old laptop--and so far I can go 5-6 hours off the charger, which is impressive for a heavy computer user like me! I use the laptop every day for several hours straight, and have many tabs and programs open and running at once on full or near full brightness. Now, to all people who are like me and will literally spend hours learning as much as they possibly can before spending a large amount of money on an investment such as a phone or laptop: I spent 16+ hours researching the budget-laptop market. My goal was to get THE ABSOLUTE BEST LAPTOP POSSIBLE FOR UNDER $300. This premium business-class notebook was recommended as the #1 laptop to buy used by hundreds of laptop owners and MANY highly regarded elite tech-reviewers all over the Internet. It cost over $1400 when it first came out in 2015, and it is now available for under $300--WHICH IS AMAZING for a laptop of this insanely good quality! As a truly satisfied customer, I can now vouch for the blazing fast speeds and mighty processing power that this 8GB RAM/Intel Core i5-5200U machine possesses. Its design is a perfect combination of sleek and light, plus durable and compact... not surprising, given that the notebooks feature an ENTIRELY magnesium alloy chassis, anodized aluminum lid and palm rests, and spill-resistant keyboard!  My overall experience with ITREPLAY surpassed all my expectations. Their customer service was FLAWLESSLY efficient and shipping came faster than expected. I can totally recommend this seller to anyone who is looking to buy from an excellent, reliable, top-quality source!
