Q. Is it possible to delete purchased Amazon Kindle ebooks from the cloud?

A. Yes, it is. Your ebook purchases are stored in Amazon's cloud so that they will be available via your account whether you use an app or a Kindle. To remove any of them though, you must go to the Amazon website. Log in there and select Manage Your Content and Devices on the account page, or via the "Hello (your name)" tab that will be at the top of the main page. After selecting Your Content you will see a list of your purchases. Click in the box to the left of any that you want to delete, and then click on the Delete button. There be will an "Are you sure?" type question, so click on Yes, delete permanently.

Q. I read somewhere that I should be able to connect my Kindle to my computer using a USB cable, and transfer e-books to my Kindle. However, when I connect the two, the Kindle goes into an unresponsive battery charge mode. What can I do to connect them properly?

A. A USB socket carries electrical power and, providing that the device being attached doesn't demand too much power, it will be recharged whilst data is being transferred. When connected to a PC, or Mac, the Kindle should display USB Drive Mode after a second or two, and should also appear in My Computer on a PC, or as mounted on a Mac. When that doesn't happen, disconnect and restart the Kindle, then go to its Home screen, bring up the menu, select Settings, then select Restart. If that doesn't work, then try connecting the Kindle to another USB port/socket and, if possible, try a different USB cable. Some Kindles are reported to have excess plastic around their USB ports, so check and make sure that the cable is fully engaged. If none of this works, then you may have a problem Kindle, and you should contact Amazon Customer Support via the Contact Us button at http://www.tinyurl.com/ye7fvr3
