- Q:Does the laptop's power adapter work when it's creaky, normal?
- As the notebook adapter is used in switching power supply,
While the switching power supply load changes little,
Work oscillation frequency in the human hearing threshold slightly higher!
Although it is also ringing,
But you will never hear!
When using the adapter as the main power supply,
It in addition to the books themselves to provide the necessary current,
But also the use of gaps for the rechargeable battery charge!
But the books due to different work procedures,
Current changes from time to time big or small!
Adapter response time slower than the books,
It has to change the oscillation frequency from time to time to adjust the output current size!
But when the oscillation frequency becomes low,
Your ears "listen" see it's shaking the hum!
Coupled with switching power supply core with energy,
Core must have a gap,
So vibration frequency will produce magnetic resonance!
This is sometimes the reason why the sound of the adapter is heard when the big time!
All the use of FM switching power supply equipment,
Will appear this situation!
Such as color TV, Di Weida machine, induction cooker, etc.!
Be assured with it!
As long as the adapter does not smoke, can work properly,
There is no problem with high temperature and hum! The The

- Q:Sony laptop power adapter there are several
- Original factory
If you want to use as long as the voltage and current can be met. But the quality of the original better, more comprehensive protection,
I used to use the computer before the thunder, was mine split, the result is only burned the adapter - the original. I have been thinking if the original will not be destroyed by the computer.
- Q:19V 3.42A notebook can use 20V 4.5A power adapter?
- It is best not to use, the voltage is too large easy to burn the power, damage to the notebook, it is recommended to use the same voltage.
The way to tell you a little power knowledge, to prevent deceived: << usually imitation of the 20-50 dollars, renovation of the original 60-150, the real original in the 150-200 between the general, and the national security >>
Need a laptop power adapter friends can go to my store to see, there are Genius original brand adapter, with the original original quality of the original, compared with the replica with the refurbished much stronger, and the price is cheap. Click on my name - login my image on the website - into my Taobao shop, you can view the details, we want to help.
- Q:Laptop connected to the power adapter, always a power will not power. Install the battery does not turn on the power adapter can be normal boot.
- This thing you use the multimeter unrealistic, the interface loose, poor battery contact, the motherboard failure is possible, you'd better get the computer city so that the master like a face experiment to show you, I most hope that the adapter has a problem, The
