The battery does not charge to the end on the laptop

What to do if the battery on the laptop does not charge at all

If the laptop does not charge the battery, and the charging is connected, most users strive to change the battery. But this is not the only way to solve the problem. Even if the nominal volume of the battery has become less than the manufacturers stated, do not rush to change it.

Determine that the battery has stopped charging when connected. It is necessary to put the mouse cursor on the battery icon in the lower right corner of the monitor. If the inscription “Connected, charges”, then it stopped working. There are three ways to solve the problem.

Weak tension

One of the most frequent reasons. You see that in the field of Windows warning there is a message that the battery is charged, and in brackets. “connected, not charged”.

Check the voltage of the mains.

Maybe the problem in the entire apartment or a specific outlet.

Turn on in another and look.

No charge with a good power supply

You, returning from a store with a brand new laptop, found that it was not charged and at the same time a licensed system was pre.Installed on it?

In this case, there may be a factory marriage, which is unlikely, or the incorrect initialization of the battery (problem with the controller).

  • Turn off the laptop itself
  • Turn off the laptop cord
  • We pull out a removable battery
  • Press the start key, holding it for 15-20 seconds
  • Return the battery to the place
  • Connect the battery
  • Turn on the laptop

These actions do not always help, but at least they are safe, easily done and you will save your time if the problem is solved.

There are two more varieties of this method:

Only for the occasion with a removable battery. Turn off the charging, stretch the battery, then press the power key and hold the minute.

After connecting in the following sequence: the battery. Charger.

The laptop must be left off for at least 15 minutes, then turn on.

When the laptop is turned on, turn off the charging without taking off the battery.

Press the start button holding until completely turned off (in most computers to click) for another minute.

After the done, connect the charging and after 15 minutes, turn on the laptop.

Operation Rules

What to do with a new laptop?

After buying a laptop, just turn it on and start working-usually laptopes are sold with a charge level of 60-70%. Then calibrate the battery: completely charge the battery (it will take about four hours), turn off the charged computer from the network and work on it until completely turned off; Then repeat the procedure again. It is not necessary to carry out calibration at full start-it is possible later, within two to three months. The programs for auto.Calibration are indicated above.

Is it possible to use a laptop constantly included in the network?

Of course not. A laptop, constantly connected to the network, can significantly reduce the battery capacity or bring to its overheating.

In what cases do you need to remove the battery?

If the laptop is always in one place and does not move anywhere, it will be more convenient to extract the battery and connect the charger. This must be done when charging about 60-70%, and then force the computer to work in deep charging mode once a month-discharge to 2-3% and charge to 60-80%.

Is it possible to throw a dead battery?

When the battery stops charging, think about where it can be applied. The batteries of the 18650 format are in the battery, not the worst. If they stopped charging, take them out using a screwdriver and pliers and use them for other purposes-for example, connect a flashlight to it or, if there is experience, make a portable Zu-Pauerbank.

If there is no application, still do not throw the “battery” into garbage. They are accepted at accumulators receiving or in separate special boxes.

How best to charge a laptop. Turned off or turned on?

The main thing is to comply with the charging mode, that is, execute the scheme of 20–80%: less than 20%. Charge, more than 80%. Disconnect from the network.

Why the battery is not fully charged?

Many users are sure that for the long.Term operation of the battery, it must be completely charged and completely discharge it. This statement is true only for obsolete nickel-cadmium and nickel-metallological batteries, which had the effect of memory. With incomplete charge, the capacity has significantly decreased in them, but now such batteries are practically not used.

In modern laptops, lithium-ion batteries are used, for the optimal work of which neither the full category, nor 100%charging are undesirable. Manufacturers took into account this moment. Many Samsung laptops are familiar with the message that appears when the cursor appears to the battery icon: “80% is available (connected, not charged)”. This means that it is in optimized mode, and further charging is not allowed by the system.

For the same reason, the ASUS laptop accumulator is not completely charged: with a decrease in the duration of autonomous work, such an option increases the life life of the battery, and this eliminates the owner of additional expenses.

Reason: wear of the battery (what is its real residual capacity)

Well, the last thing I wanted to say: it is possible that your battery was simply sat down, and therefore does not charge to the end (although, usually, the sowing battery behaves somewhat differently).

To check the status of the battery, you can use either a special. Utilities from your laptop manufacturer, or universal programs for viewing PC characteristics (for example, AIDA64, EVEREST, etc.).

The screenshot below shows the AIDA64 program, section “Power Power Stopping”. Pay attention to two values:

  • Passport capacity: maximum battery capacity declared by the manufacturer. It, of course, does not change over time;
  • Capacity in full charging: this is the actual battery capacity. Over time, it decreases. When their difference with passport capacity is 25% (cm. The degree of deterioration) or more, the battery is recommended to be changed (and the laptop will quickly sit down without a connected power supply).

AIDA 64. Full capacity and passport / degree of wear of 5%

By the way, almost the same information is given by the (Lenovo settings manager) from the laptop manufacturer, see. Screen below.

By the way, be careful with batteries, if operating (and sometimes in factory marriage), some types of such batteries can melt your laptop, burn your fingers, etc.D. Here is one example!

In general, with suspicious operation of the battery. Be extremely careful and do not leave unattended the device.

The laptop does not charge 100%

The main advantage of the laptop in front of the computer is to mobility. If necessary, you can continue to work anywhere, relying on the battery. But what to do if the laptop is not fully charged? We will consider this issue below.

If the laptop does not charge to the end, then the time of its autonomous work is noticeably reduced. Below we will consider several ways that can help eliminate the problem.

First, try turning off the laptop, disconnect from the network, and then remove the battery. Hold it in this state for a couple of minutes, insert the battery in place and start the laptop. Sometimes such a procedure helps to get rid of the problem.

If the first way did not help to eliminate the problem, try one more. Turn off the laptop, turn off the outlet, and then remove the battery. Now click on the laptop button for a minute. This procedure is carried out so that the laptop completely drops all the residual voltage. After that, return everything in place and run the laptop.

A special function of energy saving is activated on your laptop, which sheds the service life of a battery constantly operating from the network.

For example, the special menu “Easy Settings”, which controls this function on Samsung laptops is caused by the key F1. In the window that opens, disconnect the item “Extension of the service life of the battery“.

If these two methods have not brought any result, probably the problem is much more serious than you can imagine.

In this case, it is better not to engage in amateur performances, but immediately contact the service center, where specialists will conduct diagnostics and will be able to summarize what exactly caused the strange behavior of the laptop.

The laptop does not charge up to 100%: the case is the BIOS setting

Many buyers of modern laptops are faced with this problem from the first day of purchase, sometimes trying to hand over the device under warranty. If you also find the “incomplete charge” of the new device, we recommend that you look at what level the battery is charged to When the charge stops at 80% (± 2-3%), there are no reasons for panic. It’s all about “green” settings.

Modern manufacturers are concessed by the governments of countries requiring the pace of aging of electronic devices and the volumes of “electronic” waste. One of the measures to achieve this goal is to slow down the natural degradation of batteries by limiting the “ceiling” of the charge. As a rule, the setting is activated or deactivated in BIOS/UEFI. To turn off the option, you need:

Plugged In, Not Charging Windows 10 Solution (2 Methods)

  • Go to BIOS. Here it all depends on the specific model and manufacturer, we recommend reading the instructions;
  • Find the Battle Long Life option there or similar;
  • Transfer it to the Disabled position.

In some cases, it is not necessary to go to BIOS. We recommend that users of Samsung laptops and some ASUS models look for a system application with the name Battle Manager in the system tray or the like. In its settings, you can also disable the option “Optimization of the charge”.

Important! The laptop will begin to charge normally only after maintaining changes in the BIOS or system utility and subsequent rebooting!

If the desktop computer is discharged, stops working, slowly recharge or does not charge at all, remember:

  • The battery, especially new, rarely fails;
  • Most often, a power supply and connectors wear out;
  • Perhaps it is just worth updating the drivers.
  • If Li-Ion and Li-Pol AKB is used for more than 3-7 years, buy a new.

If your battery is new, do not rush to run to the store for a new one: first check all the options specified in this article and the video given.
