Charges your smartphone through the USB port of a connected computer. How to get the USB port charging function
We all know that when the laptop is powered up, all USB ports are live, and we can charge the phone by connecting them to the laptop. Why do you want to charge your phone if your laptop is turned off? So why do you need to charge your iPhone or Android phone when your laptop is frozen or in sleep mode?
As a rule, we charge our phones by connecting them to our computers. This works well if you are working or playing during the charging hour. You melodiously noted that if you close the laptop lid or your computer goes into sleep mode, your phone will stop charging.
You can charge your phone or any other USB device, or your laptop, so your laptop knows that your laptop supports this function. Also, not all laptops send life to USB ports when they are connected. The device's battery drains, causing the phone to no longer connect to the laptop.
If your laptop supports this function, one or more USB ports on the laptop will allow you to keep up with life after the laptop is turned off. The USB port may display an icon that indicates that the USB port is not active when the laptop is turned off. For example, the ThinkPad 450s has a battery icon on one of the USB ports to indicate that it will not be active when the laptop is not working.
If you need to use USB ports after the laptop is turned off, it does not take away your life, check the BIOS settings, make sure that the BIOS is configured to enhance and enable these functions. You can also check the customer service number for your laptop or contact the distributor to find out how to use the USB port device if you are not using it.
This is how you can continue to charge your phone, keep the laptop lid closed, or use the computer in sleep mode.
The method works in Windows 7, 8, 10.
Croc 1: Open Device Manager, right-click on Explorer “ This computer", Select « Power", then press the button “ The left side has a window.
Croc 2: Find and light the section USB controller.
You will get a number of devices from them "Root USB hub".
Croc 3: Essential for skin care "Root USB hub" open Powerful. In the USB hub power window, go to the “ tab Electrical utilities management" and remove the ensign from "
Once you have installed the “Root USB Hub” for all devices, you can charge your phone, use it with the laptop lid closed, or in sleep mode.
Many people still remember those “old-time” clocks, since there were very few devices that were charged through the USB ports of computers or laptops. Mostly it’s just the iPod (or any other similar player).
In just a few years, you can also charge dozens of smartphones via USB. Then now the “actions” have changed to “everything”, plus they have also acquired all sorts of 3G routers, fitness trackers, portable speakers and a host of other gadgets that we literally can’t live without regular connections to USB.
Even if you don’t mind the arrival of the whole Windows 10, the USB-based problem is still there: as soon as the computer or laptop freezes or goes into sleep mode, its USB ports also stop “providing power” and nothing else works. charge. True, Windows laptops have been released before and are now being released, with USB ports that continue to function in sleep mode, but, as practice shows, not all computer users know about them.
That's why people who are smart, who continue to practice the “old school” method of charging via USB, can easily keep their computers turned on immediately when they need to charge their smartphone or any other mobile device. The method, of course, is time-consuming and effective, but, unfortunately, it is not the most convenient and is not at all economical in terms of wasting electricity (including those that have to be pulled from the laptop battery in such situations).
In connection with this, it is clear how to charge mobile electronics through the USB port of a Windows-powered computer, or more precisely, how to configure your computer so that it is in sleep mode by supplying energy to its USB ports.
First, we need to adjust, as a matter of routine, we carry out a mini-inspection of USB ports for overconversion, which among them are present, which are adjusted to work in charger mode with the computer turned on. If your computer (more precisely, the motherboard) has such a function, then the so-called charge-friendly USB driver of the machine is liable to be produced in a different color.
To change the settings for the USB port, go to “ Device manager " and there - at the sections " USB controller “. The list has a familiar row “ Korenevy USB hub «.
For everything, there will be a lot, you will need more than that, the order of which names are indicated in the arms (xHCI) . This port is USB 3.0. Right-click on one of them and in the menu it will be stamped “ Powerful “. Then go to the tab “ Electrical control ", enable the option (uncheck the box)" Allow this device to be used to save energy » and embossed OK .
Now, with your computer turned on, you can charge various mobile devices via this USB. If one is not enough, try connecting another (if not). It’s entirely possible that you only end up sharing one, since you can’t turn on the charger mode for all USB devices this way. Moreover, the charging option via USB may not be activated so easily when the computer is turned on (we won’t go into detail about why this is so). Aside from the descriptions, the method most often works.
Many modern phones, especially those brought overseas, are charged via the USB input of a computer or laptop. Charging with an additional charging device is impossible for them for a number of reasons. This is the power of koristuvachev who work at home or on a PC. What is even more important is the ability to charge your phone when your computer is turned off. For example, the phone's battery was dead this evening, and the computer was already turned off. Should we turn the PC off now? Not obov'yazkovo. There is a way out of the situation.We will need to make changes to the BIOS settings, after which the USB port will be charged before connecting to a new device, while the computer itself will be turned off. The problem lies in the fact that this function is hidden behind the mentality. Our task is to include all functions and improve capabilities.

The problem lies in the fact that this function is hidden behind the mentality. Our task is to include all functions and improve capabilities.
The order of actions of the koristuvach will be:
1. If the PC is locked, it must be reinstalled in order to enter the BIOS settings. To do this, press one or more keys several times during the re-activation process. Depending on the type of motherboard, the input will be different, some Bios developers thought little about the comparison of their version with analogues from other manufacturers. For the example, we point out the keys for entering the BIOS for the main types of boards:
- Award BIOS – supported Ctrl+Alt+Esc or Del key;
- AMI BIOS – F2 or Del key;
- Phoenix BIOS – update Ctrl+Alt+Ins(S, Esc).
2. In the BIOS menu you will find a section called “Advanced”. All sections are located at the top of the screen in the form of a horizontal menu.
3. Next you need to know the "AdvancedPowerManagement" section. The menu will be more vertical.
4. In the menu of this product, find the row “Legacy USB Support”. You will notice that opposite it is the “Auto” parameter. It is necessary to change this by setting the value to “Enabled”. Use the Enter button and the cursors.
5. The exit from configuring the BIOS from saving parameters is completed. As a rule, the F10 key is pressed.
After completing these steps, you can safely turn on the computer and connect your device to the USB port, which will be charged.
There are many reasons for the inconvenience of charging smartphones on a computer or laptop.
It is increasingly possible that this method of charging is harmful to the battery of the device. Is it really like that? Let's find out.
Computer USB port
The main idea is that smartphones are charged on a PC, even those that are connected to an additional charging device. There is also the problem that such charging consumes the battery's old age, through which it loses capacity and is therefore discharged faster. This is partly true, but it is necessary to pay more attention to the details.
It appears that the USB ports located on the front panel of the system unit (often USB 2.0) do not provide the necessary charging circuit for full battery life. However, this problem is irrelevant because you charge the gadget through the connectors on the back of the system unit, which does not use the USB 3.0 interface. Here everything is stored in the computer and the device that is charging.
Charging speed and power flow
There is another problem that lies in the voltage and power supply in the USB ports. It changes frequently and creates a lot of thermal energy, which drains the battery life. According to studies conducted in the USA, when the battery is regularly heated to 40 degrees Celsius over several months, its capacity drops to 65%.
It is important to know that the voltage in the interfaces is the same (5V), otherwise the power supply increases:
- USB 2.0 – 500 mA.
- USB 3.0 – 800 mA.
It is recommended to choose more daily interfaces - they are often blue in color, and they have more contacts. Obviously, charging the phone to a computer via a USB 3.0 port will work faster than via USB 2.0, but in most cases it will be faster and less via .
In fact, you can charge a smartphone on a PC or laptop, but if you don’t want to cheat, it’s better to choose the original charging unit. It turns out that when charging your phone on a PC, there are many more minuses and fewer pluses. The remaining ones are no longer handy for the koristuvach.
