Computer repair providers in Miami 2025: It’s an incredibly small chance that someone qualified to carry out your IT repair will ever put your data at risk. Regardless, we strongly recommend you back up your information anyway to eliminate the potential of losing potentially irreplaceable data. Backup data using an online cloud system or an external hard drive. Whether you use your computer for personal use or you’re running a business, data back up should be a process that you follow strategically and regularly to avoid any loss of data.
Turn off extra visual effects (Windows Vista and 7). If you are using Windows Vista or Windows 7, the Aero desktop effects may be slowing your computer down. Disabling these effects is highly recommended for older computers, and can result in a big performance boost. Reinstall your operating system (OS). Oftentimes the easiest way to speed up your computer is to wipe it clean and start from scratch. Reinstalling your OS usually won’t take more than an hour or so. This will erase your entire hard drive, and will often make your computer operate as if it was brand new. See the following articles for details on reinstalling specific OSs.

Usefully, Microsoft is making the option to restart apps you were running before you restarted Windows easier to find (previously this option was tied to the “Use my sign-in info to automatically finish setting up my device” option under Sign-in options in accounts settings). It’s now off by default, including for UWP apps, which start minimized and suspended. Under Settings > Accounts > Sign-in options, turn on “Automatically save my restartable apps when I sign out and restart them after I sign in.” under “Restart apps” to change this behaviour.
From the Start menu, type Disk Cleanup. This opens the trusty Disk Cleanup utility that’s been part of Windows for several generations of the OS. Disk Cleanup finds unwanted junk such as temporary files, offline Web pages, and installer files on your PC and offers to delete them all at once. You may even find that your Recycle Bin is bulging at the seams. This will generally only have a noticeable effect on speed if your drive is getting close to full, however. If you don’t have disk defragmentation scheduled regularly, set that up in the Optimize Drives tool, which you can find by typing its name in the Cortana search box next to the Start button. Note that if your main disk is an SSD, then you needn’t bother with defragging, since there aren’t any moving parts reading the disk.
Backing up your data regularly is an overlooked step in personal online security. The top IT and security managers follow a simple rule called the 3-2-1 backup rule. Essentially, you will keep three copies of your data on two different types of media (local and external hard drive) and one copy in an off-site location (cloud storage). If you become a victim of ransomware or malware, the only way to restore your data is to erase your systems and restore with a recently performed backup. Don’t use a public Wi-Fi without using a Virtual Private Network (VPN). By using a VPN, the traffic between your device and the VPN server is encrypted. This means it’s much more difficult for a cybercriminal to obtain access to your data on your device. Use your cell network if you don’t have a VPN when security is important.
I said in the beginning that there were a few caveats. The Voltage needs to be the same or at least very close to that required by the laptop. We would generally not recommend using a charger or more or less than 1V of what is required by the laptop. HP have 18.5V, 19V and 19.5V laptops and we’ve never had a problem with supplying either of these charger for any HP laptop. Fujitsu laptops generally require 20V, but we’ve never had a problem with 19V chargers. You can not however use a 15V charger on a laptop that requires 19V or vice versa. The Polarity must match. Barrel connectors usually have the negative on the outer sheath and the positive inside the inner hole and to be honest we have never come across a laptop charger which is different.
Once you’ve found a charger that provides the correct amount of power, the next step is to determine your polarity. For barrel-style plugs, you’ll see a symbol with a “+” and “-“ sign, connected to a ring and a dot. The symbol connected to the outer ring represents the polarity of the outside of the barrel. Similarly, the sign connected to the dot represents the polarity of the inside of the barrel. Most devices use an adapter with the positive connector on the center, but there are exceptions.
