In theory, yes. In actuality, mostly no. From one brand and model to the next, most PCs operate at the same voltage, plus or minus a bit, and use mostly the same hardware inside purchased from the same suppliers, batteries included. What can vary in batteries is the physical size, location and type of connectors, storage capacity and hardware/software for communication and control. Batteries tend to be of custom size by brand and model to fit into the compartment available, Also, some brands do have proprietary battery firmware. Can you put a Ford engine into a Chevy? Sure, but the size, the connections and the management is going to take a lot of effort to get it to work. Cheaper and easier to put a Chevy engine into a Chevy. Same with batteries. For both PCs and phones, there are aftermarket batteries for some models that may fit and work. They don't tend to be of the same quality as an OEM part and frequently have less storage capacity (fewer mAh). You have to be careful when you order an extra battery from a third party seller, sometimes there's an obvious reason why what you're looking at is cheaper than what the manufacturer sells.

I hope you're able to get your PC cleaned up. If this is an instance of the installation of unwanted items and that's happened before, that might suggest that your security software isn't doing its job. And/or that your internet use habits need to be reviewed a bit. Once you get things back to normal, if you're not using one already, you might consider using a well rated security system. When you use a comprehensive program, utilities like Win Patrol become unnecessary. Attached as information for other readers is a link with trusted ratings of available programs. The not-free versions tend to be more comprehensive. The better rated free ones are capable but many have fewer features. Getting a multi-user license you share within your family or friends can reduce the cost. Also, many internet providers provide top rated products for free to subscribers. Good luck Antivirus software ratings

You have to have a picture of the book jacket on your computer first. You can do that by actually taking a picture of it (assuming you have the book) and putting it on your computer the way you would any other picture or by saving an image of it that you find on Amazon or Goodreads etc to your computer. From there, when you are on the club website and click to upload a picture, go to wherever you have stored the image.

I quoted your words, there was nothing to assume. In response to your words, I said I thought it wasn't a good idea to keep a backup drive connected to a PC for the reasons I mentioned. Immediate, right at the moment backups are rarely necessary. Most programs do that as a normal feature on the installed drive anyway, to protect against user error. If the external drive is not left connected to your PC, how does it do backups "Every time a document is saved or changed". Again, those are your words. I've learned to quote what you say that I'm commenting on because you've used the "that isn't what I said" response before. If I've copied your words into quote marks inaccurately, you can explain further so that I and other readers can better understand. Or don't, it doesn't really matter.
