How does Lenovo charge B450AT6570 laptop, and what is the sign that it is charging and filling

To see if the charge is fully charged, you can open the Control Panel (in the Start menu or My Computer) and look at the Power Options, from where you can see if the charge is fully charged. Or you install a "Master Lu" software, run it, and you will find that there is a power display in the taskbar at the bottom of the desktop.

Lenovo B450AT6570 laptop is not expensive at 4000 yuan, and the cost performance is quite high. The heat dissipation performance is quite good, and the leather is durable. But there are relatively few features.

There is no Bluetooth, the camera is still 300,000 pixels, with a microphone and mono audio. So the entertainment function is not very good. But if it's an office, it's preferred.

And the after-sales service is very good, and the maintenance is convenient.

Since we are currently mainly responsible for Lenovo Android platform smartphone and tablet business consulting, please understand that we may not be able to give you a more accurate answer to PC related questions.

Here we recommend that you get help in the following ways:

The above are all wrong, the current laptop batteries are not needed, charge and discharge three times, charge and discharge three times refers to the previous nickel-metal hydride battery, now it is a lithium battery or lithium polymer battery, the manufacturer has already specified the parameters when manufacturing the battery, so there will generally be no problem.

Then the charger you said is very hot is a normal phenomenon because when charging, the transformer in the charger is working, he is the largest source of heat for the entire charger, and according to the surrounding situation, it will be cooler in winter, and it will feel hot in summer, and it is normal to heat up like a notebook in about 90w, and it is not a mobile phone, ***, mp4 and the like, their power is calculated in mw (milliwatts), basically it will not be very hot, Sometimes it's cold to the touch.

You said that the charger is cold after 5 hours, that's because the electricity is finished, the notebook is about 6 hours, like some notebooks support 1 hour full of about 70%, full of about 3 hours, 12 hours is the previous battery practice, now there is no need, like a new battery, only you need to charge it for two more hours after you are fully charged, and it is enough to do this three or four times.

We are sorry, but we are currently mainly responsible for Lenovo Android platform smartphone and tablet business consulting, and we are not familiar with PC related issues, please understand.

Here we recommend that you get help in the following ways:

12 hours means that the machine you just bought should be charged and discharged three times, and each time it is fully charged for 12 hours, before the electricity is used up. It's not that the next charge will be twelve hours. 5 hours is definitely a good wash. Do not worry.

No problem, in the future, you only need to charge for 3 hours to fully pull, the first three times is to let the battery have a memory, to avoid being undercharged, but the battery permanently loses part of the power. The quality of B450 can be assured, if you are not assured, you can call ** consultation, if there is a problem, you can replace it within 15 days. Hehe, I wish you a happy use.
