Your laptop isn't slow because it's old. It might be starving. 🔌

Use the wrong charger — or hang a phone charger, a fan, and a mug warmer off your dock — and the machine throttles itself down to survive. We've seen it in the field more than once, and every time the owner thought the computer was dying.

The face on your video call might not be real. Deepfakes can now fake a familiar face and voice live, and people have been talked into wiring out fortunes. If someone on a call pushes you to move money fast, verify another way first. Call them back on a number you already have.

You're probably holding way more customer data than you need: old card numbers, files from clients who left years ago. If you don't need it, it's just data for a hacker to steal. Delete what you've no reason to keep, old payment details first. You can't lose what you don't have.
