Reformat your devices!

Over time, personal devices and computers can become slower to respond to actions, gestures, or to boot up applications. When this starts to happen, generally we think of what kind of device or computer we want to replace our old ones with.

A great thing you can do instead is to refresh, or reformat your device! By formatting your device to factory settings, it can help prolong the life of your device/computer and keep it running fairly quickly. However, make sure you properly back up your data on your device/computer before you reformat it: follow the 3-2-1 backup rule.

Huawei is Back

Huawei is Back

Episode 1604

Leo doesn't really get what's going on, but it appears that Huawei is now allowed to be sold in the US. For the last few years, Huawei was declared as a "dangerous foreign entity," but now it appears that at the recent G20 summit, the President has officially lifted all restrictions.

Why Does My Computer Wake Up from Hibernation?

hibernation

Episode 1570

Greg from Saratoga, NY

Greg put his laptop in hibernation, and when he woke up this morning, it was on. How did it come out of hibernation? Leo says it's common that if there's an update or some preset network activity (like "Wake-on-LAN"), the computer can wake up. A tremor can wake it up as well. As a rule, Leo doesn't recommend hibernation because it can confuse the operating system, causing issues when waking up. Just let it go to sleep. Users can log out, though, for security issues.

Episode 1569

Andy from LaHabra, CA

Linux

Episode 1554

Larry from Cerro Gordo , CA

Larry built his first computer in high school, running Linux, and it's 15 years old. Lately he's been having power issues and he has replaced the power supply, but still has the problem. Leo says that indicates a deeper problem on the motherboard. It could also be a failing video card, and the CMOS settings may be corrupted. Removing the battery and putting it back in will reset everything, but he may want to make sure all the cables are seated, and that the RAM is properly installed.
