Is it good to take off the battery when the HP 4411s425 is connected to an external power supply

Now laptops have control chips... The battery doesn't need to be taken off at all. It's not good to take it down... The battery will not be charged until it has not dropped much power.

Dizzy. Said a bunch of them.

The only advantage of using the battery without removing it is that in the event of a power outage, the computer can be used as usual without data loss due to power failure.

A laptop without removing the battery is equivalent to charging and using it at the same time, and the current is still transmitted to the computer through the battery.

When I saw that it was an HP laptop, my first impression was that the accessories you got were old refurbished or inferior products.

Many cases of poor battery charging are related to the IC of the battery, and when the gold medal service is retrieved, it is found that the battery cannot be charged, and the service personnel will quietly perform an IC correction, so there is no problem on the surface.

HP laptops have always had a lot of potential failures, and if there is a problem with the battery, you can buy a matching assembled battery online to use. When returning to the factory, you must confirm that there is a fault that cannot be repaired on the spot at the service station, and you are more depressed about this problem. In addition, HP's return to the factory is more disgusting, if the notebook is returned to the factory and sent back, there may be a lot of old parts on the new machine, or even bad parts.

In addition, HP should also return unconditionally within 15 days, and it would be good to return it when it encountered a problem.

Buy HP and regret dying.

If you encounter a problem, you can solve it.

Depend on. They are good, and they die and do not admit that there is a problem with the machine.

Alas, I also have exactly the same problem as you, I went to buy it on January 25, 2010 with my colleagues in the unit, at that time, it was 4411s248 and took nearly seventy tribes of my machine after ten days of use, I used Master Lu to detect that the battery capacity was lost more than ten percent, I had a feeling of uneasiness in my heart, to the twenty-ninth of the lunar month, when the battery showed that it could be used for nearly fifty minutes, so I charged it, with Master Lu a test, the results showed that there were ten hours to be full, At that time, I wondered, I just turned off the charge to see what it was, and it really took ten hours to be full, and on the second day of the first month, I used the battery of the machine to start charging after prompting to charge, and the result was even more unjustifiable, and it took 18 hours to be full. Due to the holiday, the dealer did not open the door, had to stay until the eighth day of the first day to go to the dealer, to him to change and not change, no way to have to test the machine, after using up the electricity as long as nearly an hour is full, but at this time another problem appeared, the electric display is full but the charging switch is not turned off, the machine is still displayed in the charging, no way to have to pass the dealer to Wuhan after-sales detection, to that, the service staff said that the test machine is no problem, but after charging for a period of time, the instructions from yellow to green, so that I tried there for two days, After-sales hit ** said no problem, so folded to the fifteenth day of the first month I went to Tianmen to get back the computer, the day to get back the display of 65% of the electricity, I charged for more than an hour to fully charge, and full after the instructions turned off, but the light color change is still the same, I am now uneasy in my heart, for fear that there will be a mess in the future. It seems that this HP is a lot of problems, which is really reassuring.

When you go to the after-sales service, the charging adapter and power supply are your own and return them?
