Isidor Buchanan, editor of Battery University, recommends that users put their phones or laptops in cool places so that the device's battery life is longer. Meanwhile, behavioral surveys showed that many people often put their phones in the front / back pants pocket, in direct contact with body temperature; others put laptops on thighs or blankets and cushions. This not only poses a risk of fire and explosion, but also makes the battery completely empty.

Ideally, keep your phone in a bag. When using it, it is recommended to place the laptop on a cool glass table, not absorb heat.

Put the damaged hard drive in the refrigerator

When your hard drive gets hit, can't read the data anymore, don't throw it away, pack it carefully and put it in the refrigerator for a night. Anyway, you think it's broken so try this last way.

" This tip has been proven and considered a last resort, " said Fred Langa on Windows Secrets. "In many cases, the hard disk is broken because the parts in it are cracked, not arranged properly, so the data cannot be read. Lowering the temperature for the hard disk will help the metal and plastic parts shrink. A little bit, can put the broken part into the original position, then put the hard disk into the normal environment to try again ".

The basic principle of " physical shrinkage at low temperatures, high temperature expansion " can help the hard drive recover enough for you to retrieve the necessary data, even if it won't "last". long.

If you're lucky enough to own a home that is so big that Wi-Fi router waves can't reach the farthest part, don't rush to buy additional transceivers. Instead, you can make a fairly passive passive radio reflection system from kitchen utensils like . aluminum wheels.

There are many different designs depending on your skill. However, these patterns follow a general principle that two 36 cm2 square reflectors are bent into a parabolic shape that fits into the router's antenna. See how to do it here.
