Plugged in not charging

On some devices, like my work Lenovo laptop, it'll stop and just trickle charge when the battery is at 97%. That's a feature, not a bug, designed to help avoid overcharging and damaging your battery and device. Try running on battery for a little while and reconnect the AC adapter. You should notice it's charging again. If it doesn't, post back.

Whether laptop for a better power supply that was being? We have been asked many questions that.

The following is an excerpt from BIGLOBE of e-mail magazine. Please refer to.

"Compared to when you buy a laptop, battery less of became fast", "as much as possible the laptop battery want to last longer!" To anyone who wants.

In order to preserve as much as possible the life of the G74SX battery, I will introduce a point and tricks you want to be careful!

Caution those who have this kind of use!

Did you mean, why not or not use while charging the laptop?

Many, lithium-ion batteries of the battery being used in laptop battery. This battery, charging becomes violently degradation and followed by a state that is a 100 percent, I would shrink the life of the battery (?) is.


Attention also anyone who "every day, have a charge the laptop before going to bed." Battery has been said that the number of times that can be charged about 500 times. In addition, the battery as long as they continue to charge, tries to keep 100% of the full charge. However, in practice, always because it has happened discharge is in the personal computer, it is finely repeatedly that state because charging, the consumption ? battery charge the battery is 100% ? discharge.

Therefore, you can not use while plugged the AC adapter into an electrical outlet in the same sense as the desktop personal computer, and has a charge every day, the life of the Sony battery will become more and more short.

Smartphones, also has been used a lithium ion battery and the laptop. This article also ne please refer to!

? To extend battery life, the three causes of the daily ed] & battery deterioration to note this!

? In the article, the life of the battery, it points a state in which the capacity is reduced by half, which can be charged as compared to when new.

And ... in order to prolong the life of the battery

The first is, that it is not used while charging the laptop.

As mentioned above, using a laptop while plugged the AC adapter into an electrical outlet, the life of the rechargeable battery will become more and more short. "Less likely to bring a laptop to the outside, it is often used in a fixed location of the room," anyone who wants to, there is also a hand in that, should remove the battery except when you carry around.

The second is, that you do not blindly charge.

If you have to charge every day, it is will be increased, but the number of charges by that amount of course. And such as a battery is charged only when the cut 20%, you can reduce the number of charges to be decide my own rules.

Third, that the bear in mind as much as possible to 80% charge.

If there is an item that can be set the state of charge of the battery of the laptop power settings, it can be set so as not to be in full charge (?).

I have to try that "sub-zero beer" to drink at home, "Strong via cooler"

For example, in the case of certain laptop DELL, proceeds HP charging battery in the Control Panel ? Power Options ? desktop mode, you can set the use of the from the desktop mode tab, battery.

? Whether or not there is a power setting, it is more on the model of the laptop

The battery is a consumable. Please, let as much as possible long-lasting using it well!

My lenovo G460 laptop doesn't turn on ?

Did you have exhausted the battery power? If so, maybe the laptop can't turn on as soon as you plug in the ac adapter, as you can try to let the laptop charged for a time and then turn on the laptop to see if every thing is well.

My laptop is not charging even it is plugged in.

There are two possibilities here.
1) Your charger is faulty or there is a break in the wire.
2) Your laptop's battery is dead.

How old is the laptop? Is it the same battery that came with the laptop when you bought it? When you use the laptop at home or at work do you normally plug it into AC power with or without the battery in the laptop?

I am not able to open my laptop lenovo G460

Hi kabi_a11,

If you're unable to turn on your laptop there's a big chance that you're having power issue. Consider checking your Battery, AC adapter and DC In port.

1. Basic troubleshooting for battery is by reseating it. Kindly make sure to put it back properly.

2. For the AC Adapter, check the light indicator for it. If it's not defective you'll see the blue light on the brick. You may also try using other AC adapter with same power supply. And if other AC adapter works with your PC then it's the AC adapter that goes with your PC needs to be replaced.

3. One of the possible cause for your computer not to turn on is because the DC In port for the machine is loosed. No power will flow from your AC adapter to your PC.

If after checking and still computer won't turn on I will now recommend you to contact the manufacturer. Lenovo offers repair if machine is under warranty.

Hope this helps.

Thank you for using Fixya.

Charging problem ; charger is ok but it seems like there is a problem with the actual internal charging device.

There could e a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.

Laptop crashes shortly after boot, power light rapidly blinks red.

Its late, so just to make sure I'm not brain-dead basically your laptop runs fine as long as its powered by the AC adaptor but dies fairly quickly while running via battery. This is very typical of a battery that will no longer hold a charge, not normally a user repairable item. It could also be that the charging electronics (in the laptop) isn't charging the battery, again not a typical user repair job. About your only option short of taking it to the repair shop is buying or borrowing a battery as a test.
