Not charging laptop battery

notebook as a stand-alone (portable) computer, equipped with a battery capable of repeated recharging, that is the battery.It is required to have a high specific capacity and tightness.These requirements are currently best suited for lithium-ion batteries.Even in small devices such as cellular telephones, the power consumption is large enough, and their lithium batteries provide power for an extended period of time.

When the laptop it is observed a constant balance between mains and battery.This deals with a special driver, which is available in any OS: Windows, Linux, and others. Control of the state of battery charge is conducted by various methods.There are reasons for an objective assessment of the chemical batteries in principle, impossible.Therefore, using several indirect methods.The easiest - measurement of the voltage at the terminals.A better method - counting the number of electricity, "the departed" to the battery, in coulombs or ampere-hours.It can be used a combination of these methods, plus a statistical algorithm, which may be called "wear."Manufacturers of batteries for its set rate, the value of which gradually decreases over time.This is reflected in the state of charge.

If the battery is not charging the notebook, it does not mean that it is necessarily faulty.The system, that is, the driver power, may find that it is already charged, and the icon will show "100%".Disconnect the computer from the network and work on the battery before it is fully discharged.When the power supply supervisors (special chips that keep them in good power supply to the processor, and the like) will be served a critical alarm, the driver will record the complete discharge of the battery, and then prepare your system for emergency shutdown.

Turn the machine back to the network, do not start downloading.Look at the indicator located somewhere on the rim of the notebook (near the power connector).If the battery is not charging the notebook, you will not see the glow indicator.Typically, deep discharge it glows yellow color.Remove the battery and check its appearance.Clean the contacts and make sure the battery is nowhere vspuh and not cracked.Replace and start again.If you still not charge the battery on a laptop, this can be a problem charging circuit in the computer.For diagnostics try to take another battery or put it into another laptop.This method will cause an exception exactly.Most likely, if the laptop battery is not charged, it should not give the charge and, in the event of their failure.

If the process has started, wait until you see the indicator glow blue.Then you can start the car without "zaparivaya" PSU double load - because the battery continues to charge.But now she works in a mode of recharging and takes less current.

Look at the monitor power system.For Windows, Linux GNOME or KDE, in general, any "Desktop", a small icon with tips that will state: "charge / run from the network" and the interest of completeness charge.If a laptop battery does not charge for a long time, say, only 96%, there may be an effect intensity of the load on the computer.

Typically, this happens when the laptop is used in several ways.For example, listening to music, play, and at this time is carried out more download any film.And you notice that the processor is buzzing, the disc heats up, the fans are blowing at full capacity.But perhaps the reason is the aging of the battery is elementary, and after some time will need to be changed.

Thus, if the laptop battery is not charging, do not worry, and perform simple manipulations, which have been described above.
