Batteries power our favorite electronic devices, but they’re not meant to last forever. The good news is that Windows 10 laptops have a Battery Report feature that breaks down whether your battery is still kicking or is on its last legs. With a few simple commands, you can generate an HTML file with battery usage data, capacity history, and life estimates. If it needs to be replaced, this report will tell you, long before it has a chance to fail.

Adobe Acrobat has a couple of different software options for handling PDF files to choose from—Acrobat Standard DC and Acrobat Pro DC. The standard version is for Windows only, while the pro version works with both Windows and Mac.

These run for $12.99 and $14.99 per month, respectively, so unless you’re already using one of these, it’s probably not worth the money just to convert a PDF file to PowerPoint. However, Adobe Acrobat is the best program on the market for anything dealing with PDF files, so we’d recommend subscribing to one if you frequently do any sort of work with PDF files. Best yet, Acrobat Pro DC has a free trial, so if you’re unfamiliar with Adobe Acrobat, it costs nothing to give it a try.

In this example, we’ll be using Adobe Acrobat Pro DC. Open the PDF file you’d like to convert. In the right-hand pane of the window, select “Export PDF”.

Google collects and remembers information about your activity, including your web, search, and location history. Google now auto-deletes history for new users after 18 months, but it will remember history forever if you previously enabled this feature with the default options. As an existing user, to make Google delete your data after 18 months, you’ll have to go into your activity settings and change this option. You can also tell Google to auto-delete activity after three months or stop activity collection entirely.

To find these options, head to the Activity Controls page and sign in with your Google account if you aren’t already signed in. Click the “Auto-delete” option under Web & App Activity.

Your Mac automatically remembers W-Fi networks you’ve connected to in the past. However, the network it automatically connects to might not be the best option. Here’s what to do if you want your Mac to forget a Wi-Fi network.

In addition to removing old connections, forgetting a Wi-Fi network can help you troubleshoot connection issues. If a network has changed its password and your Mac doesn’t give you a password prompt (or if it’s just being flaky), you can try forgetting and rejoining the network.

To do so, click the Wi-Fi icon in your Mac’s menu bar, and then select “Open Network Preferences.”

Here, click “Advanced.”

Most mice have two main buttons: the primary button and the secondary button. The primary button is usually on the left side of the mouse, but some users prefer to swap them if they are left-handed or have a different preference. Here’s how to do that on your Mac.

First open System Preferences by clicking on the Apple logo on the menu bar then selecting “System Preferences.”

In System Preferences, locate “Mouse” and click on it. This will open the mouse options.n Mouse options, find the “Primary Mouse Button” section, then select either Left or Right depending on your personal preference. The default primary mouse button is Left, but some right-handed users use the Right button as primary.

Li-Fi stands for Light Fidelity and is a Visible Light Communications (VLC) system which runs wireless communications that travel at very high speeds.With Li-Fi, your light blub is essentially your router. It uses common household LED light bulbs to enable data transfer, boasting speeds of up to 224 gigabits per second.The term Li-Fi was coined by University of Edinburgh Professor Harald Haas during a TED Talk in 2011. Haas envisioned light bulbs that could act as wireless routers.Subsequently, in 2012 after four years of research, Haas set up company pureLiFi with the aim ‘to be the world leader in Visible Light Communications technology’.

Li-Fi and Wi-Fi are quite similar as both transmit data electromagnetically. However, Wi-Fi uses radio waves, while Li-Fi runs on visible light waves.

As we now know, Li-Fi is a Visible Light Communications (VLC) system. This means that it accommodates a photo-detector to receive light signals and a signal processing element to convert the data into ‘streamable’ content.An LED light bulb is a semiconductor light source meaning that the constant current of electricity supplied to an LED light bulb can be dipped and dimmed, up and down at extremely high speeds, without being visible to the human eye.

For example, data is fed into an LED light bulb (with signal processing technology), it then sends data (embedded in its beam) at rapid speeds to the photo-detector (photodiode).

The tiny changes in the rapid dimming of LED bulbs is then converted by the ‘receiver’ into electrical signal.

The signal is then converted back into a binary data stream that we would recognise as web, video and audio applications that run on internet-enabled devices.
