My old laptop Presario CQ61-421SG had suddenly turned abruptly while working. Only now I noticed that the battery was completely empty, which meant that the power supply provided no electricity. After measuring with a meter to my confirmed Suspicion. After a short search at Amazon, I had suitable power supply, a low-cost third-party product found. Today, the network has been partially delivered. Everything works again. The laptop battery is charging and operation over the power grid works ebefalls properly. My conclusion: a very good buy!
