The software can vary from laptop models, but if Microsoft Office isn't available pre-installed, it can be downloaded from Microsoft directly, or you could purchase an edition of Office products from Best Buy directly. The download version will offer a trial period of a month before a registration key must be purchased.

None of our laptops come with full versions of Office pre-installed at the time of this posting.

What's likely happening is that your wrist is brushing up against the touchpad, which may be quickly highlighting text, and replacing it with what you're typing at the moment.

One recommendation might be to use a USB mouse, and change your mouse settings to "disable the touchpad when the USB mouse is attached". This way, whenever you're typing and have your mouse plugged in, you're not brushing against the touchpad.

The Geek Squad can also help you find this setting, if you're interested in taking your computer in - that way you have a solution for this issue.

You can use Tablets when you travel, although we do recommend purchasing a device in the region where it will be most used.

We can't determine specifically for the LA40C650L1F model, since it's not a U.S. model.

However, if the unit requires the WIS09ABGN, the WIS12ABGNX will be a compatible replacement part for use in the U.S. It would seem to make sense that it would also replace other overseas models, but again, we cannot confirm. We encourage you to reach out to the Samsung customer service center in your region to confirm for the LA40C650L1F model to confirm before purchasing.

Thanks for your interest in Samsung wireless adapters.
