This product itself is fine, but I had a huge amount of static coming from it and malfunctions while plugged in. This was due to a generic off-brand charger. Only realized this once damage was already done. Why be so stingy with a small thing, that can mess up a whole system? Why not mention it in product description? 1 star, amazon renewed.Great laptop though. Pity the battery is now damaged as well, thanks to this crummy non-lenovo charging block!
