How do I know PC power supply failure?

The story,

The power distribution in many industrial areal aren't so consistent. Therefore we frequently have dead PC power supply.

So if we cannot turn on the PC, how do we know if it is the power supply failure and not the motherboard?

Here's a simple solution,

  1. Open the PC casing, and look for a small LED green light (mostly beside the power connection to the motherboard. 
  2. This is a power standby indicator that signal there is power into the motherboard.
  3. If there is green light when AC power from wall socket is turned on, this signal that the power supply is OK and vice versa (picture below).
  4. If there is no light, change a new power supply.
  5. If after change the power supply also no light, then it's the motherboard problem.



Additional note :
  • Don't attempt the repair the power supply unless you are a trained electrical technician. The power supply is so cheap that it's not worth to repair even you are a technician or engineer.
  • There are still charges in the capacitor that might kill you even it's not plugged in. Don't pass these hazardous things to children or anyone else. Stay safe.
  • To keep your power supply healthy and lasting, I suggest you use a AVR (automatic voltage regulator  or UPS (uninterruptible power supply) regulate the AC input power.

Increase PC life span, sleep, hibernate, or shutdown?



The story,

People always ask me how to increase the lifespan of their PC or laptop. If they really want it to last very very long,  I would suggest keep if off and don't use it ... just joking :-).

Amazingly, PC components nowadays are built to last even we never turn it off. In fact, some reports show that PC last longer without turning it off.

But there are things that we must consider, heat and vibration. If you don't want to turn off the PC/laptop, make sure it is in a cool place and not getting lots of vibration (Don't move or carry it around).

Here's a link to Cnet  forum for more information.

ATTENTION MY FRIENDS!!



Just now when I logged into my SkyDrive, it showed 'upgrade 7GB to 25GB free'.

Wonder how will Google Drive or Dropbox respond to this.

If  each give 25 GB free, we would have 75GB free. :-)

Lets hope so!

P.S. If you are wondering what is cloud storage, let me explain. Cloud storage is a virtual storage in the internet that act like a hard disk in your computer. You can copy and save any files into the virtual storage and the files can be accessed from the Internet on any PC, tablet or smartphone with Internet access.

However, the files aren't stored in your PC, it will be stored in the server in the Cloud Storage provider. You must have Internet to use it.
