Computers like any piece of technology, are susceptible to the passage of the years, it is best to give them maintenance regularly and follow some tips to keep them in good condition.
These are some 10 myths that exist around the personal computers, some are certain and others, not so much:
1. Turning the computer off at once can damage it:
Yes and no. The hardware does not suffer any damage, but the operating system or some program could be damaged if a write-in process is interrupted when it is occurring, explains Christoph de Leuw of Computerbild magazine.
2. You have to wait 15 seconds before turning on a computer again:
“There is no reason for it,” says expert Michael Schmelzle, unless you have to reset the BIOS chip, which “needs about 15 seconds to download.” Otherwise, with current computers this is no longer a problem.
3. The more cores and gigas a processor has, the faster it is:
In principle it is true, says the expert Thomas Rau, from the German magazine “PC Wel”: But the key is whether the software in question can use multiple cores or not. In a current device, where several programs usually work at the same time, it is always better to have multiple cores. But much also depends on the structure of the core and the frequency of operation.
4. With saving processors, less energy is spent:
No. They are set to cool less when the use is less, but they are effective almost only in the case of laptops. These type of processors are an indicator but no guarantee that the battery will last longer. Even if the processor saves power, the rest of the computer could be so badly designed that the components drain the power.
5. Defragment the computer from time to time:
It used to be that way, but since Windows 7, Microsoft’s operating systems do it on their own. In the case of SSDs it is even important not to do so, because they “clean” themselves in a different way.
6. You have to remove the usb in the correct way
The expert Georg Schnurer says that “The devices themselves do not break,” but what can happen is that if they are recording data at the time, they are lost when disconnected. The worst thing that can happen is that the unit can no longer be read and formatted. “And so all data is lost.”
7. Magnets Damage Hard Drives and USB Memory
That’s impossible in the case of USB drives, says Schnurer, but it’s different with hard drives. A normal magnet that can be at home does nothing, but if you take a magnet especially strong as a neodymium, in some cases it may be that data is lost.
8. Wait until the batteries are exhausted to recharge them:
No, with lithium batteries this is no longer necessary. “Manufacturers recommend that they be completely emptied once when they are new to calibrate them with operating system battery level indicators or software tools,” explains Schnurer.
9. You have to use a screen saver:
This holds true for old cathode ray monitors, says Schnurer, but not with the current ones. What does make sense is to program the system so that the screen turns off when not in use, which saves energy.
10. Golden HDMI cables transmit a better picture:
They may look more “luxurious”, but they are the same as silverware in terms of operation.
