A:AnswerI don't see anything about a six-month free trial of ANY anti-virus from Best Buy, so that might just have been a one-time offer. However, like all Windows 10 and 11 OSs, it comes with Windows' own malware protection, called Defender. This will be sufficient for most people. If you want more than that, there are a few free antivirus applications you can find, either on the MS Store or via Google. Also, many ISPs provide a free program for subscribers, so you can investigate that. If none of the above are applicable to you, you will have to pay for something the Norton, Trend, or McAfee.
A:AnswerNot advised. A laptop is made to operate on a certain base (unconnected) power and a specific extra energy supply (plugged in). Just as you wouldn't arbitrarily connect it to the different types (voltage, wattage, AC frequency) of power in different countries, you can't shove in some random battery that fits in the physical space and has jury-rigged connectors. This is especially true for lithium batteries, which all laptops use, since these batteries are prone to burst into fire or even explode when incorrectly charged.
A:AnswerI can, and so can you. Open the Microsoft Store and search "exit s mode."
Also, everyone who tells you you can't restore S mode is completely incorrect. There are two basic ways to do so. The easiest is to perform a factory reset. This method does have the drawback of wiping your drive, however.
